Introduction to Shock Relays
At Tsubaki, our commitment is to bring you the highest value in the
industry today. Period. And as a full line supplier of power transmission
products this commitment extends to our complete line of Shock Relay
products as well.
Protect your equipment and investment with Tsubaki shock relays and
external current transformers. Unexpected shock loads can damage
chains, drives, gears, turbines – the entire mechanical assembly. That
means high maintenance, costly repairs, and expensive downtime.
Simply put, when the shock relay detects a problem, it shuts down the
line – quickly, safely and securely. That means big savings in both time
and money.
After the problem is corrected, the shock relay is reset at the touch of a
button. No tear down is required. That means improved efficiency and
reduced downtime.
P.T. Components
And it’s all part of the Tsubaki Advantage: reliable premium products
that don’t just perform, they outperform the competition. All the while
saving you money.

Explanation of Terms
Start Time
During startup, the current draw of a motor is greater than the running current. In order to prevent the shock relay from engaging
during startup, the start time of the shock relay is adjustable from 0.2 seconds to 30 seconds. The shock relay will only trip when the
current draw of the motor exceeds the trip current and when the start time is reached.
Test
The test button simulates a current overload.
Trip Current
The trip current level is user adjustable and varies according to the shock relay model selected - see specification chart on the
following page for complete details. When the actual current level exceeds the preset current (outside of the shock time range), the
shock relay will trip.
Reset
The reset button will reset the shock relay after a current overload.
Connection Terminals (contacts)
There are 5 connection terminals:
L1 & L2: These terminals are used to provide power (from 90VAC to 240VAC) to the shock relay.
95, 96 & 98: These terminals provide output from the shock relay. The application - such as a motor - can be wired into these
terminals. When the shock relay trips, the circuit opens and the application stops.

Explanation of Terms (Continued)
Start Time
During startup, the current draw of a motor is greater than the running current. In order to prevent the shock relay from engaging
during startup, the start time of the shock relay is adjustable from 0.3 seconds to 12 seconds. The shock relay will only trip when the
current draw of the motor exceeds the preset current and when the start time is met.
Shock Time
This feature allows the shock relay to ignore normal machine fluctuations, yet react when a true problem develops. The shock time is
adjustable from 0.3 seconds to 3 seconds. The shock relay will only trip when the current draw of the motor exceeds the trip current
and when the shock time is met.
Alarm Current
An alarm can be connected to the terminals on the front panel of the shock relay. The alarm current can be set to between 50% and
100% of the trip current level. This allows for a pre-alarm warning when the current draw is approaching the preset current level.
If an alarm is not being used, the alarm current setting can be set to the “off” position.
DIP Switches
The shock relay has 4 DIP Switches that toggle between two settings and that allow the shock relay to be configured for a particular
application.
The DIP switches are:
1: “No Voltage Release” (on/off) This switch changes the status of contacts 95-96 and 97-98. For example, in left-hand position
contacts 95-96 are normally closed; and in the right-hand position, contacts 95-96 are normally open. This adds flexibility to aid
installation.
2: “Phase Loss Protection” (on/off) When set to the “on” mode (right hand position), the connected motor will shut down if one of
the three phases of the motor drops out. The motor will also shut down if there is a phase imbalance. The “off” mode (left hand
position) disables this feature.
3: “Reset” (manual/automatic) When set to the “manual” mode, if the shock relay trips due to current overload or phase failure,
the shock relay must be reset manually by pushing the “reset” button. In the “automatic” mode, the shock relay automatically resets
one second after the current overload causes it to trip. Also in the “automatic” mode, the shock relay must be manually reset after
phase failure causes it to trip.
4: “Alarm Relay’s Movement” (flicker/continuous) This feature works with the alarm current setting. In the left-hand position,
“flicker” mode, when the alarm current setting is met, the alarm will activate by blinking/flickering one time per second. Essentially this
and when the current drops to normal, the alarm will stop. If the situation is not corrected and the shock relay trips, (shutting down the
application) the alarm will stay on, but now blinks/flickers at a rate of two-times per second. In the right-hand position, “continuous”
mode, the alarm will be activated when the motor current is between the pre-alarm set point and the overload trip point. If the current
drops below the setting or if the shock relay trips, the alarm will turn off.

Connection Terminals (contacts)
There are 4 sets (pairs) of connection terminals.
A1 & A2
These terminals are used to provide power to the unit.
95 & 96
These terminals are for the trip output relay and are “normally closed”. The application - such as a motor - could be wired into these
terminals. When the shock relay trips, the circuit opens and the application stops.
97 & 98
The circuit connected to these terminals is “normally open”. A warning device such as an alarm or light could be wired into these
terminals. When the shock relay trips, the circuit closes and the warning device is activated.
07 & 08
These terminals are used to connect an alarm. This circuit is “normally open”. When the alarm set point is reached, the circuit closes
and then the alarm is activated. This could be considered a pre-alarm to indicate the potential for a problem should the current
increase further.

An Introduction to
Power-Lock
The traditional and popular "industry standard”, the keyed mount has a number of widely acknowledged limitations. In a keyed
connection the clearances that must exist between the component hub, shaft, keyway, and key allow for metal-to-metal contact leading
to fretting and corrosion. The poor fit also allows "backlash" to occur during the starting, stopping and transmitting power during normal
operation. The process of machining the keyway into the shaft is tedious, permanent and expensive. It also reduces the strength and
amount of torque a given shaft size can transmit. Another popular connection system, the interference fit also has limitations.
Interference fits or welds prevent the operator from being able to easily remove the shaft from the hub for maintenance or
replacement.
Tsubaki has been a leader within the power transmission industry in the quest to find a better way to connect components to shafts.
The Tsubaki Power-Lock is a well-engineered, adjustable and affordable device that solves engineering and maintenance difficulties
associated with other connection alternatives. Tsubaki Power-Lock is a shaft-to-hub friction connection that relies on concentric
surface pressure to affix gears, sprockets, and other drive components to a motor-driven shaft. Power-Lock improves the connection
of a drive component to a shaft. It helps to eliminate problems with keyway connections and limitations for QD and tapered bushings.
This frictional, keyless system enables transmission of high-torque and axial loads, and accommodates reversing, dynamic or shock
loading. Tsubaki Power-Locks can be used in such common applications as the connection of timing pulleys, sheaves, conveyor
pulleys, indexing applications, sprocket, gears, cams, levers, motors and hydraulics, clutches and brakes and flange couplings.
Power-Lock is available in both Inch and Metric sizes in a variety of styles.
The Power-Lock allows for easy attachment of shaft to hub without time and money spent on machining or extra assembly labour.
Power-Lock connects hubs solidly to shafts, using a keyless mechanical interference fit to transmit torque or to withstand axial thrust.
This mechanical interference fit utilizes screw tension in the Power-Lock, converted into radial pressure. This pressure expands the
Power-Lock to eliminate the gap between the hub and the shaft. The Power-Lock uses the friction bond between the Power-Lock and
the shaft/hub to create a zero backlash connection. This connection is easily releasable to remove the mechanical interference fit.
The contact pressures created using a Power-Lock can be greater than traditional interference fit pressures, allowing for more torque
to be transmitted or shorter hubs to be used. The easy installation also allows the hub to be positioned more accurately on the shaft,
and can facilitate angular timing of the hub.

AS Inch/Metric Series
Power-Lock
AS type Power-Locks are our most popular style. They can be assembled and disassembled frequently so that maintenance or
replacement of worn hubs is simple and easy as compared to other methods. They are easy to install, adjust or remove, but are not
self-centering. A precentering hub section is usually required. The Tsubaki AS Power-Lock uses an inner, collet-like, sleeve with a
tapered O.D. and an outer sleeve with a tapered I.D. The tapers are identical, but
opposing to one another. The inner sleeve fits around the shaft while the outer
sleeve fits inside the hub bore of the component to be mounted, such as a pulley,
gear, chain sprocket or other component. Upon tightening the loading mechanism,
the bolts forces the inner sleeve to squeeze onto the shaft and the outer sleeve to
expand outward against the component hub bore. This mechanical shrink fit resists
shock and torque reversals eliminating key wallowing, backlash and fretting
corrosion associated with a keyed mount. The AS Power-Lock allows a given shaft
size to transmit more torque than if it had a keyway, or both the shaft and peripheral
components can be downsized reducing weight and cost. With a keyless
connection, the gripping stress is evenly distributed 360° around the O.D. of the
shaft and the I.D. of the component hub bore instead of being concentrated at the
key and keyway. These units are most commonly used on applications in general
engineering to transmit high torques and axial loads utilizing larger machining
tolerances. AS Power-Locks are available in inch and metric sizes and also in stainless steel.

AS Inch/Metric Series
Power-Lock
Selection Guide:
1. a) Determine the required maximum torque (MtC) to be transmitted:
Torque MtC = 5252 x HP (ft-lb)
RPM
b) If combined torsional and axial loads are to be transmitted,
calculate the resulting torque as follows:
Mt res =
MtC2 +
(F24x d)2 < M
t
Where:
Mt res = resultant torque to be transmitted
MtC = actual or maximum torque to be transmitted (ft-lb). This value is calculated in step 1 a) above.
F = axial load/thrust to be transmitted (lbs)
d = shaft diameter (inches)
Mt = maximum transmissible torque (ft-lb) of the Power Lock as specified in the AS Power-Lock specification tables.
2. Select a Power-Lock for the shaft diameter (d) from the AS Power-Lock specification tables in this catalogue and verify that the
corresponding maximum transmissible torque (Mt) meets the torque requirement that was calculated in step 1 a) above. If torque is
the primary requirement, select the necessary torque (Mt) from the same specification tables and determine the corresponding shaft
diameter (d).
Note: Required peak torque should never exceed specified transmissible torque (Mt).
To increase transmissible torque (Mt):
Install 2 or 3 Power-Locks in series, increasing transmissible torque as follows:
- with 2 Power-Locks: Mtrans.= 2 x Mt
- with 3 Power-Locks: Mtrans.= 3 x Mt
The hub must be long enough to accommodate the assemblies.
3. Determine the recommended minimum hub outside diameter (DN) for the Power-Lock selected from the specification tables (which
show the DN for material with a yield point of 32,000 p.s.i.) For other yield point materials, calculate the hub outside diameter (DN) by
using the following equation:
DN > D x
YP + (K3 x pH)
YP - (K3 x pH)
(inches or mm)
Where
D= Outer diameter of the Power-Lock and hub counter bore inside diameter (inches or mm).
YP = yield point of hub material (p.s.i. or MPa)
pH = Contact pressure between the Power-Lock and hub bore. See specification tables (p.s.i. or MPa).
K3 = 0.6 (one Power-Lock)
K3 = 0.8 (2 or 3 Power-Locks in series)
See Hub layout diagram on next page for more detail on value of K3
P.T. Components
Note: Use either all imperial values (inches/p.s.i.) or all metric values (mm/MPa) when calculating the value of DN.
F-13
AS Inch/Metric Series
Power-Lock
4. Verify that the hub length (B) is adequate for the selected Power-Lock; see Example below.
5. Check the applicable machining tolerance for the shaft and hub bore in the specification tables. A surface finish of 125 micro-inches
for shafts and bores is generally adequate.
Fig. 1 (Single Power-Lock)
where B > 2l
Fig. 2 (Multiple Power-Locks)
B > n • 2Lt
where n = number of Power-Locks
and where 2 < n < 4

EXAMPLE
A sprocket is to be mounted on a 1.50” shaft capable of transmitting a peak torque of 400 ft-lb. The sprocket is made of 1144 steel
with a yield point of 56,000 p.s.i. Select the proper Power-Lock and determine the required hub dimensions and proper machining
tolerances.
a. The shaft diameter (d) is specified at 1.50”.
b. The AS Power-Lock specification tables indicate that a 1.5” Power-Lock is capable of transmitting a torque (Mt) of 658 ft-lb, which is
more than the required amount of torque (400 ft-lb) given in this example. Select the PL 1 1/2 Power-Lock.
c. Use the formula in step 3 in the Selection Guide on the previous page, to determine that the selected PL 1 1/2 Power-Lock requires
a minimum hub outer diameter (DN) of 3.03” based on Y.P. 56,000 psi hub material.
d. The hub length (B) shown in figure 1 should be > 2 x l. The specification table for AS Power Lock PL 1 1/2 indicates that l = 0.709”
therefore, B > 2 x 0.709 > 1.418
P.T. Components
e. According to the AS Power-Lock specification tables, the machining tolerances for the selected AS Power-Lock are as follows:
shaft (d): 1.50” +.000/-.0015”
f. Order the following assembly:
Size 1 1/2

Installation
1. Verify that all contact surfaces, including the screw threads and screw head bearing surfaces, are clean and lightly oiled.
Note: Do NOT use Molybdenum Disulfide, “Molykote” or any other similar lubricants.
2. Slide the Power-Lock onto the shaft and into the hub bore, aligning them as required.
3. Tighten the locking screws gradually in the sequence illustrated in Figure 1 below. The tightening sequence is as follows:
a) Hand-tighten 3 or 4 equally spaced locking screws until they make contact. Align and adjust the connection.
b) Hand-tighten and take up all remaining locking screws.
c) Use a torque wrench to tighten the screws further to approximately one-quarter the specified torque (MA - as found in the AS
Power-Lock specification tables).
d) Increase the tightening torque to 1/2 of MA.
e) Finally, use the torque wrench to tighten the screws to the full tightening torque (MA).
f) Verify that the screws are completely tight by applying the specified tightening torque (MA).
Notes:
i) Even tightening is best accomplished by turning each screw in increments of approximately 90˚.
Fig. 1: Tightening Sequence For Locking Screws.
(This is only an example - other number of
locking screws is possible)
Removal
AS Power-Locks are not self-locking. The individual rings are tapered so that the inner and outer rings will spring apart after the last
screw has been loosened.
1. Loosen the locking screws in several steps following a diametrically opposite sequence. Do not remove the screws completely.
2. Remove the hub and Power-Lock from the shaft.
P.T. Components
Note: If the AS Power-Lock is still locked even after loosening the bolts, then insert bolts into the jack screw holes (see photo
below) and screw them in until it unlocks.

AD Metric Series
Power-Lock
The AD Metric Series Power-Lock has the similar construction to the AS Metric Series Power-Lock. The major difference is that the
AD Series has over two times greater transmissible torque than that of the AS Series. The AD Metric Series and the AS Metric Series
have the same inside and outside diameter.
Selection Guide:
1. a) Determine the required maximum torque (MtC) to be transmitted:
Torque MtC = 5252 x HP (ft-lb)
RPM
b) If combined torsional and axial loads are to be transmitted, calculate the resulting torque as follows:
Mt res =
MtC2 +
(F24x d)2 < M
t
Where:
Mt res = resultant torque to be transmitted
MtC = actual or maximum torque to be transmitted (ft-lb). This value is calculated in step 1 a) above.
F = axial load/thrust to be transmitted (lbs)
d = shaft diameter (inches)
Mt = maximum transmissible torque (ft-lb) of the Power Lock as specified in the AD Power-Lock specification tables.
2. Select a Power-Lock for the shaft diameter (d) from the AD Power-Lock specification tables in this catalogue and verify that the
corresponding maximum transmissible torque (Mt) meets the torque requirement that was calculated in step 1. a) above. If torque is
the primary requirement, select the necessary torque (Mt) from the same specification tables and determine the corresponding shaft
diameter (d).
Note: Required peak torque should never exceed specified transmissible torque (Mt).
To increase transmissible torque (Mt):
Install 2 or 3 Power-Locks in series, increasing transmissible torque as follows:
- with 2 Power-Locks: Mtrans.= 2 x Mt
- with 3 Power-Locks: Mtrans.= 3 x Mt
The hub must be long enough to accommodate the assemblies.
3. Determine the recommended minimum hub outside diameter (DN) for the Power-Lock selected from the specification tables (which
show the DN for material with a yield point of 32,000 p.s.i.) For other yield point materials, calculate the hub outside diameter (DN) by
using the following equation:
DN > D x
YP + (K3 x pH)
YP - (K3 x pH)
(inches or mm)
Fig. 1 (Long Hub with Guide)
where B > 2l
K3=0.6
P.T. Components
Where
D= Outer diameter of the Power-Lock and hub counter bore inside
diameter (inches or mm).
YP = yield point of hub material (p.s.i. or MPa).
pH = Contact pressure between the Power-Lock and hub bore.
See specification tables (p.s.i. or MPa).
K3 = Form factor depending on hub design-see Fig. 1, Fig. 2 or Fig. 3
Note: Use either all imperial values (inches/p.s.i.) or all metric
values (mm/MPa) when calculating the value of DN.
4. Verify that the hub length (B) is adequate for the selected
Power-Lock.
5. Check the applicable machining tolerance for the shaft and
hub bore in the specification tables. A surface finish of
125 micro-inches for shafts and bores is generally adequate.

Installation
1. Verify that all contact surfaces, including the screw threads and screw head bearing surfaces, are clean and lightly oiled.
Note: Do NOT use Molybdenum Disulfide, “Molykote” or any other similar lubricants.
2. Slide the Power-Lock onto the shaft and into the hub bore, aligning them as required.
3. Tighten the locking screws gradually in the sequence illustrated in Figure 1 below. The tightening sequence is as follows:
a) Hand-tighten 3 or 4 equally spaced locking screws until they make contact. Align and adjust the connection.
b) Hand-tighten and take up all remaining locking screws.
c) Use a torque wrench to tighten the screws further to approximately one-quarter the specified torque (MA - as found in the AD
Power-Lock specification tables).
d) Increase the tightening torque to 1/2 of MA.
e) Finally, use the torque wrench to tighten the screws to the full tightening torque (MA).
f) Verify that the screws are completely tight by applying the specified tightening torque (MA).
Notes:
i) Even tightening is best accomplished by turning each screw in increments of approximately 90˚.
Fig. 1: Tightening Sequence For Locking Screws.
(This is only an example - other number of
locking screws is possible)
Removal
P.T. Components
AD Power-Locks are not self-locking. The individual rings are tapered so that the inner and outer rings will spring apart after the last
screw has been loosened.
1. Loosen the locking screws in several steps following a diametrically opposite sequence. Do not remove the screws completely.
2. Remove the hub and Power-Lock from the shaft.
Note:
• If the AD Power-Lock is still locked even after loosening the bolts, then insert bolts into the jack screw holes (see photo below) and
screw them in until it unlocks.

Power Lock Dimensions
KE Inch Series
Power-Lock
KE Power-Locks are self-centering and are ideal for A type sprockets and narrow gears. It is designed with a slit construction and
special taper angle to cover a wide tolerance of shaft sizes, such as motor shafts. Available in a variety of sizes, including fractional
inch sizes for smaller motors.

Selection Guide:
1. a) Determine the required maximum torque (MtC) to be transmitted:
Torque MtC = 5252 x HP (ft-lb)
RPM
b) If combined torsional and axial loads are to be transmitted, calculate the resulting torque as follows:
Mt res =
2
MtC +
(F24x d)2 < M
t
Mt res = resultant torque to be transmitted
MtC = actual or maximum torque to be transmitted (ft-lb). This value is calculated in step 1 a) above.
F = axial load/thrust to be transmitted (lbs)
d = shaft diameter (inches)
Mt = maximum transmissible torque (ft-lb) of the Power-Lock as specified in the specification tables in this catalogue.
2. Select a Power-Lock for the shaft diameter (d) from the KE specification tables in this catalogue and verify that the corresponding maximum
transmissible torque (Mt) meets the torque requirement that was calculated in step 1. a) above. If torque is the primary requirement, select the
necessary torque (Mt) from the same specification tables and determine the corresponding shaft diameter (d). Note: Required peak torque should
never exceed specified transmissible torque (Mt).
To increase transmissible torque (Mt):
Install 2 Power-Locks in series, increasing transmissible torque as follows:
- with 2 Power-Locks: Mtrans.= 2 x Mt
The hub must be long enough to accommodate the assemblies.
3. Determine the recommended minimum hub outside diameter (DN) for the Power-Lock selected from the specification tables (which show the DN for
material with a yield point of 32,000 p.s.i.) For other yield point materials, calculate the hub outside diameter (DN) by using the following equation:
P.T. Components
DN > D x
YP + (K3 x pH)
YP - (K3 x pH)
(inches or mm)
Note: Use either all imperial values (inches/p.s.i.) or all metric values (mm/MPa)
when calculating the value of DN.
Where
D= Outer diameter of the Power-Lock and hub counter bore inside diameter (inches or mm).
YP = yield point of hub material (p.s.i. or MPa)
pH = Contact pressure between the Power-Lock and hub bore. See KE Power-Lock Specification Tables (p.s.i. or MPa).
K3 = Form factor depending on hub design (see Fig.1, Fig.2, or Fig.3).
4. Verify that the hub length (B) is adequate for the selected Power-Lock.
5. Determine the applicable machine tolerance from the KE Power-Lock Specification Table.

Installation
1. Verify that all contact surfaces, including the screw threads and screw head bearing surfaces, are clean and lightly oiled.
Note: Do NOT use Molybdenum Disulfide, “Molykote” or any other similar lubricants.
2. Slide the Power-Lock onto the shaft and into the hub bore, aligning them as required.
3. Tighten the locking screws gradually in the sequence illustrated in Figure 1 below. The tightening sequence is as follows:
a) Hand-tighten 3 or 4 equally spaced locking screws until they make contact. Align and adjust the connection.
b) Hand-tighten and take up all remaining locking screws.
c) Use a torque wrench to tighten the screws further to approximately one-quarter the specified torque (MA - as found in the KE
Power-Lock specification tables).
d) Increase the tightening torque to 1/2 of MA.
e) Finally, use the torque wrench to tighten the screws to the full tightening torque (MA).
f) Verify that the screws are completely tight by applying the specified tightening torque (MA).
Notes:
i) Even tightening is best accomplished by turning each screw in increments of approximately 90˚.
Fig. 1: Tightening Sequence For Locking Screws.
(This is only an example - other number of
locking screws is possible)
Removal
KE Power-Locks are not self-locking. The individual rings are tapered so that the inner and outer rings will spring apart after the last
screw has been loosened.
1. Loosen the locking screws in several steps following a diametrically opposite sequence. Do not remove the screws completely.
2. Remove the hub and Power-Lock from the shaft.

Note:
• If the KE Power-Lock is still locked even after loosening the bolts, then insert bolts into the jack screw holes (see photo below) and
screw them in until it unlocks.

AE Metric Series
Power-Lock
The AE Metric Series Power-Lock features a single taper design with a self-locking taper to provide good self-centering action and concentricity. The AE
Metric Series Power-Lock is used wherever self-centering action and good concentricity of mounted components is essential and where hubs with
straight-thru bores are used. The AE Metric Series Power-Lock has the same inside diameter and outside diameter as the AS Metric Series Power-Lock;
and so they are interchangeable with each other in many applications..

Selection Guide:
1. a) Determine the required maximum torque (MtC) to be transmitted:
Torque MtC = 5252 x HP (ft-lb)
RPM
b) If combined torsional and axial loads are to be transmitted, calculate the resulting torque as follows:
Mt res =
MtC2 +
(F24x d)2 < M
t
Mt res = resultant torque to be transmitted
MtC = actual or maximum torque to be transmitted (ft-lb). This value is calculated in step 1 a) above.
F = axial load/thrust to be transmitted (lbs)
d = shaft diameter (inches)
Mt = maximum transmissible torque (ft-lb) of the Power-Lock as specified in the specification tables in this catalogue.
2. Select a Power-Lock for the shaft diameter (d) from the AE specification tables in this catalogue and verify that the corresponding maximum
transmissible torque (Mt) meets the torque requirement as calculated in step 1. a) above. If torque is the primary requirement, select the necessary
torque (Mt) from the same specification tables and determine the corresponding shaft diameter (d). Note: Required peak torque should never exceed
specified transmissible torque (Mt).
To increase transmissible torque (Mt):
Install 2 or 3 Power-Locks in series, increasing transmissible torque as follows:
- with 2 Power-Locks: Mtrans.= 2 x Mt
- with 3 Power-Locks: Mtrans.= 3 x Mt
The hub must be long enough to accommodate the assemblies.
3. Determine the recommended minimum hub outside diameter (DN) for the Power-Lock selected from the specification tables (which show the DN for
material with a yield point of 32,000 p.s.i.) For other yield point materials, calculate the hub outside diameter (DN) by using the following equation:
DN > D x
YP + (K3 x pH)
YP - (K3 x pH)
(inches or mm)
Note: Use either all imperial values (inches/p.s.i.) or all metric values (mm/MPa)
when calculating the value of DN.
P.T. Components
Where
D= Outer diameter of the Power-Lock and hub counter bore inside diameter (inches or mm).
YP = yield point of hub material (p.s.i. or MPa).
pH = Contact pressure between the Power-Lock and hub bore. See AE Power-Lock Specification Tables (p.s.i. or MPa).
K3 = Form factor depending on hub design (see Fig.1, Fig.2, or Fig.3).
4. Determine the applicable machine tolerance from the AE Power-Lock Specification Table.

Installation
1. Verify that all contact surfaces, including the screw threads and screw head bearing surfaces, are clean and lightly oiled.
Note: Do NOT use Molybdenum Disulfide, “Molykote” or any other similar lubricants.
2. Slide the Power-Lock onto the shaft and into the hub bore, aligning them as required.
3. Tighten the locking screws gradually in the sequence illustrated in Figure 1 below. The tightening sequence is as follows:
a) Hand-tighten 3 or 4 equally spaced locking screws until they make contact. Align and adjust the connection.
b) Hand-tighten and take up all remaining locking screws.
c) Use a torque wrench to tighten the screws further to approximately one-quarter the specified torque (MA - as found in the AE
Power-Lock specification tables).
d) Increase the tightening torque to 1/2 of MA.
e) Finally, use the torque wrench to tighten the screws to the full tightening torque (MA).
f) Verify that the screws are completely tight by applying the specified tightening torque (MA).
Notes:
i) Even tightening is best accomplished by turning each screw in increments of approximately 90˚.
Fig. 1: Tightening Sequence For Locking Screws.
(This is only an example - other number of
locking screws is possible)
Removal
P.T. Components
AE Power-Locks are not self-locking. The individual rings are tapered so that the inner and outer rings will spring apart after the last
screw has been loosened.
1. Loosen the locking screws in several steps following a diametrically opposite sequence. Do not remove the screws completely.
2. Remove the hub and Power-Lock from the shaft.
Note:
• If the AE Power-Lock is still locked even after loosening the bolts, then insert bolts into the jack screw holes (see photo below) and
screw them in until it unlocks.

EL Metric Series
Power-Lock
EL Power-Locks are a frictional keyless locking device for connecting hubs and shafts that are subject to large torque variations. The
EL Power-Lock is a simple structure consisting of two tapered rings. They are ideal for fastening gears, pulleys, sprockets, cams, etc.
to metric sized shafts from 10mm to 150mm. They are perfect for applications requiring timing and backlash-free connections. When
locking force (F) is applied to the EL Power-Lock, it pushes the inner and outer rings together, generating radial direction pressures
(pH and pS) on the shaft and to the hub bore. These pressures (pH and pS) create the friction fit connection.
Construction
Selection Guide
3. Determine the required locking force (PA) from the EL
Power-Lock Specification Tables.
EL Series Power-Locks must be used with metric shaft sizes.
For EL Series Power-Lock, in addition to (PA), a preload
(PO) is required to bridge the clearance for the specified fit.
The required total locking force for solid EL Series Power-Locks
is: PA’ = PO + PA
(see the EL Power-Lock specification tables).
The locking force is normally obtained by using multiple locking
screws and a clamp ring or flange.
4. Determine the number, size and grade of screws to be
used based on the required locking force and individual
screw clamp load (see Table 1).
1. a) Determine the required maximum torque (MtC) to be
transmitted:
Torque MtC = 5252 x HP (ft-lb)
RPM
b) If combined torsional and axial loads are to be transmitted,
calculate the resulting torque as follows:
Mt res =
MtC2 +
(F24x d)2 < M
t
P.T. Components
Where:
Mt res = resultant torque to be transmitted
MtC = actual or maximum torque to be transmitted (ft-lb).
This value is calculated in step 1 a) above.
F = axial load/thrust to be transmitted (lbs)
d = shaft diameter (inches)
Mt = maximum transmissible torque (ft-lb) of the Power-Lock as
specified in the specification tables in this catalogue.
2. Select an EL Series Power-Lock for the shaft diameter (d) from
the specification tables and verify that the corresponding
maximum transmissible torque (Mt) meets the torque
requirements.
Note: Required peak torque should never exceed specified
transmissible torque (Mt). Catalogue values for (Mt) are based
on a contact pressure of 14,220 p.s.i. between the shaft and the
EL Series Power-Lock in a lightly oiled installation. Higher torque
capacities can be obtained by using 2 or more EL Series PowerLocks in series.

5. Determine the size of clamp ring or flange based on the bolt
circle diameter and the thickness of the clamp ring or flange.
c) Recommended clearance “x” and maximum values for R are
shown in the EL Power-Lock Specification Tables.
6. Determine the hub outside diameter (DN) using the EL
Power-Lock Selection Tables shown in this section.
c) Tighten the screws to full tightening torque using a torque
wrench.
d) Verify that the screws are fully tightened by applying the
specified torque.
4. Check the clearance (x) between the clamp flange and the
hub. The clamp ring should not make contact with the face of the
hub. The gap between the clamp ring and hub face should be
even all the way around.
Clamp Plate Mounting and Removal
EL Series Power-Lock Removal
There are two basic methods for mounting the clamp plate:
1. Hub bolting permits axial positioning of the hub as well as
angular adjustment.
2. Shaft bolting requires the hub to be backed against a shoulder
to support the clamping force.
Note: EL Series Power-Locks are not self-locking.
1. Remove any accumulated contaminant's from the connection.
2. Loosen the locking screws in several stages following a
diametrically opposite sequence.
3. Remove the hub and EL Series Power-Locks from the shaft. If
the EL Series Power-Lock is jammed, loosen it by tapping it with
a light hammer.
EL Series Power-Lock Installation
Since the torque is transmitted by contact pressure and friction
between the frictional surfaces, the condition of the contact
surfaces and the proper tightening of the locking screws are
important.
Fig.1 Tightening sequence example
P.T. Components
1. Carefully clean and lightly oil the shaft, hub bore, spacer
sleeves and EL Series Power-Locks.
Note: Do NOT use a Molybdenum Disulphide LUBRICANT
(“MOLYKOTE” OR THE LIKE).
2. Install the parts in the following order:
a) Hub (the play between hub bore and shaft affects the
true running of the hub).
b) Spacer sleeve to bridge the undercut (if needed)
c) Outer ring/inner ring (both parts must slide on easily).
For one EL Series Power-Lock install the outer ring first.
Otherwise, install the inner ring first.
d) Spacer sleeve and clamp flange or clamp ring (both
parts should slide on easily).
e) Carefully oil the locking screw threads and head bearing
surfaces.
Note: Do NOT use Molybdenum Disulphide.
3. Tighten the locking screws evenly and in several steps
following the diametrically opposite sequence illustrated in Fig. 1
a) Tighten the screws by hand until a slight positive contact
is established. Make final alignment adjustments to the
connection.
b) Tighten the screws to approx. one-half the specified torque
using an extended key or torque wrench.

Pro-Align® Laser
Alignment System
Introduction
Increase Productivity
Pro-Align lets you align all power transmission devices faster,
easier, and more effectively than ever before. System
misalignment is a leading cause of premature chain wear. Our
advanced laser technology ensures precise chain-sprocket
interaction for maximum performance.
Conventional alignment methods can be difficult to position,
inaccurate, and produce erratic results — costing you valuable
production time. Pro-Align gets the job done fast. It sets up
easily — even in tight spaces — and eliminates the backlash
effects of water, shock, and corrosion. You get reliable readings
right away and can quickly get back to business.
• Chain life is extended
• Requires minimal downtime, maintenance, and training
• Shafts and bearings last longer
• Adapts to your equipment with no costly reconfiguration
• Friction and vibration is lower, using less energy
• Accurate within 1/8” in 100 feet for precision applications
• Cost and inventory levels are reduced
• Maintains accuracy under the toughest operating conditions
• Compact, lightweight, portable unit
Laser
The Pro-Align laser activates with a simple
twisting motion. The level adapts to
horizontal, vertical, inclined, or restricted
measurement units with no costly
reconfiguration.
Target
Pro-Align’s custom aluminum target is
specifically calibrated to the laser to provide
immediate, reliable readings.
P.T. Components
Mounting Unit
Pro-Align’s magnetized mounting unit attaches
firmly to sprockets for maximum accuracy. A rustresistant coating protects the unit during use in
harsh applications.

These Terms and Conditions of Sale and, where applicable, the quotation, sales order confirmation, invoice and all documents
incorporated expressly by reference therein shall constitute the entire agreement governing the sale of the Seller’s products (the
“Contract”).
PRICE-PAYMENT
The prices stated are those in effect on the date hereof and are subject to change based on prices in effect on the date of shipment.
Interest at the rate of the lesser of (i) 18% per annum, or (ii) the maximum rate allowable by applicable law, shall be charged on
overdue payments. Prices are for Seller's standard packaging only, and F.O.B. Seller's plant or warehouse. All orders are subject to

(c) Should Buyer cause changes to be made in the design or construction of any products, or otherwise delay or interrupt the
progress of the work hereunder, Buyer will reimburse Seller for any additional costs arising therefrom.
(d) Seller shall not be liable for any delay caused by acts of God, riot or civil commotion, government orders, rules, regulations,
suspensions or requisitions of any kind, strikes or other stoppages of labor or shortage in the supply of labor or material, fire casualties
or accidents, or any cause, whether of the same or a different character, beyond Seller's control. Any such delay shall extend the time
for delivery of the products. Delay in delivery of any installment shall not relieve Buyer of its obligation to accept remaining deliveries.
(e) If delays due to Buyer's fault exceed 60 days in the aggregate, the entire purchase price shall be due and payable to Seller on
demand.
(f) Any claim relating to quantity or type of products ordered or shipped to Buyer shall be made to Seller in writing within 7 days after

SOLD, PROVIDED THAT THE PRODUCT OR PRODUCTS CLAIMED DEFECTIVE ARE RETURNED TO THE SELLER
DESIGNATED INSPECTION POINT, TRANSPORTATION CHARGES PREPAID BY THE BUYER, WITHIN THE ABOVE-NOTED
WARRANTY PERIOD.

long as Seller is willing and able to replace or repair any defective product in the manner prescribed above.
This limited warranty applies only to new and unused products which after shipment from the Seller’s factory have not been altered,
changed or replaced in any manner.
If, after inspection of the returned products, Seller determines that the defect is a result of misuse, mishandling, installation, abnormal
conditions of operation, unauthorized repair or modification, or due to the Buyer’s failure to install, maintain or operate the product in
compliance with the written instructions, then the Buyer shall reimburse Seller for all expenses incurred by Seller in connection with
the replacement or repair of the product. Any product returned to Seller for replacement shall become the property of Seller.
The Buyer shall be responsible for all costs of shipping, customs clearance and other related charges in connection with Seller’s
replacement or repair of products located outside of Canada pursuant to this limited warranty.
