INSTALLATION
MOUNTING TO THE CARRIAGE
The carriages in both the size LP15 and LP20 actuators have 6 mm x 15 mm deep tapped holes along
with 0.1875 dowel holes for proper alignment. When mounting a plate to the carriage, be sure that the
plate is flat to insure a complete mating surface. If the plate is not flat, or if the bolts are too long, this
action could induce a bending moment into the outside of the T-slots on the carriage. This could result in
a premature failure in the carriage and an unsafe condition.
MOUNTING THE ACTUATOR
Support of the linear actuator should only be on the aluminum extrusion body; never put supports under
the drive end or the support end. These components could misalign the ballscrew system and cause
premature failure of the linear actuator.
The body should be fully supported if practical. For long strokes, support the actuator body at least every
meter. The linear actuator aluminum bodies are provided with 8 mm wide extruded slots for mounting. The
body can be easily clamped down to the supporting plate by means of the optional clamps. Both size LP
actuators use the clamp #CL-80-39.

INSTALLATION
MOUNTING A MOTOR
All other methods of driving the input shaft should include the use of a high quality flexible coupling. Hard
coupling directly to the actuator shaft can cause excess wear and could cause a failure of the actuator.
NOTE: Bimba recommends the use of motors with a properly sized fail-safe brake on all vertical applications.
ALIGNMENTS
Care should be taken when aligning linear actuators with a moving machine component. Make sure that
any bending or twisting of the actuator from other machine components is eliminated or minimized in
reference to the linear actuator.

MAINTENANCE
GENERAL
General maintenance of the linear actuators is to keep the actuator clean to keep dirt from accumulating
inside the actuator. Inspection of the actuator, clamps, tee bolts, mounting hardware, and other parts
should be done periodically to insure proper alignment and that the operation did not change from the
initial installation.
LUBRICATION: LINEAR BEARINGS
With the new Self-Lubricant Linear Guideway
If your actuator has a serial number LP230 and above, do not use grease. Use only oil as instructed below.
The linear guide blocks are of the self-lubricant type. These blocks require oil installed into the side of the
block through the side access hole on the side of the extrusion. Simply remove the plug in the extrusion
and drive the carriage to the middle, align the oil fitting with the access hole and install the oil directly into
the block. Lubrication for these linear bearings is recommended at least every 10,000 km of travel.
Previous Linear Actuators
Lubrication is recommended for the linear bearings at least every 100 km of travel. Extreme operating
conditions (high temperatures, high speeds, heavy loading) require more frequent and/or different
lubrication.
The actuator carriages are designed to distribute the grease to the linear bearings through channels and
fittings internal to the actuator. A grease fitting is supplied on either side of the carriage for lubrication.
This fitting has a M6 thread and a needle nose ball detent interface to your grease gun.
Grease is recommended at linear speeds up to 3 meters per second and oil lubrication above 3 meters
per second. The maximum speed of the actuators should be 5 meters per second. Consult Bimba for
application data. Grease should be a lithium-based lubricant. The amount of re-lubrication of grease is 5
cm3 per bearing block. Oil should be 30~150cst with a feeding rate of 0.3 cm3/hour per bearing block.
Review your part number for the appropriate number of bearing blocks installed in your actuator.
LUBRICATION: BALLSCREW
The ballscrew supports use sealed, angular contact thrust and deep groove ball bearings with a lifetime
lubricant so that no maintenance is required.
The ballscrew and ballnut require grease lubrication. Simply lift the bellows or Stainless Steel cover and
install grease to the ballscrew. Old designs can also use the side lubrication holes and remove the plugs
from the extrusion and apply grease to the ballscrew.

DISASSEMBLY
Call Bimba before any disassembly of the linear actuator. Bimba’s warranty may be voided if the customer
disassembles the linear actuator.
Qualified personnel should do disassembly of the ballscrew actuator only. If disassembly is required, then
the first thing to be removed is the end plate covers. One of the end plate covers (on the drive end) has the
Intek logo, part number, and serial number engraved into the top surface.
Next to remove the sealing strip, end of the actuator is a sealing strip retainer, which is a steel block with
two tapped holes and knurled on top to help hold the stainless steel strip.
Remove the bolts holding the sealing strips from the retainers at each end.
Next, remove the top carriage from the bottom carriage.

SPARE PARTS
DISASSEMBLY, CONTINUED
To get to the ballscrew and the linear bearings, the aluminum cover needs to be removed. In the second
picture above, there are two BHCS on each end of the cover, remove these and the cover can then be
removed. To remove the ballscrew, the end thrust bearings must be removed and the ballnut retainer from
the bottom carriage. There are four BHCS and two dowel pins as shown below.
After removal of those, the bottom carriage can be slide out of the way as shown here.
Now the thrust bearings will need to be removed to totally remove the ballscrew. The retaining nut and the
spacer will first be removed. Then take the bearing retainer off the drive plate.

SPARE PARTS
DISASSEMBLY, CONTINUED
Removing the drive plate from the extrusion will allow you to remove the ballscrew completely from the
actuator if replacement is required.
This will also allow the bottom carriage to be slide off of the linear rails to replace the linear bearings.
When re-assembly is being done, make sure the roller guides are in place in the strip guides that are
bolted to the top carriage. (This is the bottom view.)
To reassemble, reverse this procedure, making sure that adequate tension is on the strip to insure that
buckling of the strip does not occur. The actuator should be driven back and forth numerous times to
make sure the linear bearings and the ballscrew are running true. The carriages (top and bottom) should
be indicated in with a dial indicator for run-out; hold this to +/- 0.001" to original specifications.
ORDERING SPARE PARTS
