Actuator mounted on a flat surface and fully restrained (see Mounting Plate
Requirements, page mxb_11) L = Maximum distance between supports
The listed values relating to straightness/flatness are intended for
reference purposes only, and not as an engineering standard of absolute
tolerance for a given actuator. Appropriate installation is the single most
important factor in reducing variation, so good engineering practices such as
measurement, mapping, etc. must be employed in applications with stringent
straightness/flatness requirements.

The above ratings are the maximum values for shock-free, vibration-free operation in a typical industrial environment, which must not be
exceeded even in dynamic operation. Contact Tolomatic for assistance in selecting the most appropriate actuator for your application.
The moment and load capacity of the actuator bearing system is based on an L10 life of 5,000 linear km (2x108 in) of travel. Life of
the actuator will vary for each application depending on the combined loads, motion parameters and operating conditions. The load
factor (LF) for each application must not exceed a value of 1, as calculated below. Exceeding a load factor of 1 will diminish the

Proper lubrication of profiled rail bearing system is essential
for normal operation and achievement of full rated life of
MX--P actuators. Lubrication should be performed at intervals
of 101 km (4x106 in) of travel or once every year, whichever
occurs first. However, operating conditions such as high speed or
significant shock and vibration may require more frequent lubrication. Please consult Tolomatic for recommendations.
Recommended grease types:
1.Refined mineral oil-based multi-purpose grease with lithium
thickening agent.
2.High-grade synthetic oil-based grease with urea thickening
agent.

The MXB-P is unique among Tolomatic belt drive actuators.
The mounting surface of the carrier is located 90° from the
motion of the belt. The side opposite the belt is reserved for
switch placement. The bottom of the actuator is reserved for

is mounted in the SDT (direct drive top
orientation), be sure the load mounted to the carrier does not
interfere with the motor.

MXB Rodless Belt Drive Actuator
SWITCHES
SPECIFICATIONS
MX products offer a wide range of sensing choices. There are 12 switch
choices: reed, solid state PNP (sourcing) or solid state NPN (sinking); in
normally open or normally closed; with flying leads or quick-disconnect.
Commonly used for end-of-stroke positioning, these switches allow drop-in
installation anywhere along the entire actuator length. The one-piece design includes
the retained fastening hardware. The magnet and magnet hardware are located on
the carrier. See the dimensional drawings on page mxb_23 for details of magnet and
switch locations. Switches and magnets can be installed in the field at any time.
Switches are used to send digital signals to PLC (programmable logic controller), TTL,
CMOS circuit or other controller device. Switches contain reverse polarity protection.
Solid state QD cables are shielded; shield should be terminated at flying lead end.
All switches are CE rated and are RoHS compliant. Switches feature bright red or
yellow LED signal indicators; solid state switches also have green LED power indicators.

SWITCH INSTALLATION AND REPLACEMENT
Place switch in side groove on tube at desired location with "Tolomatic"
facing outward. While applying light pressure to the switch, rotate the switch
halfway into the groove. Maintaining light pressure, rotate the switch in the
opposite direction until it is fully inside the groove with "Tolomatic" visible.
Re-position the switch to the exact location and lock the switch securely into
place by tightening the screw on the switch.

4) External guide system (if the load
is externally supported and guided,
consider using MXB-U)
Choose an actuator that has the thrust,
speed and moment load capacity to
move the load.
A) For maximum thrust use the table below.
B) Max. speed of MXB-U 200 in/sec
(5 m/sec); Max. speed of MXB-S
100 in/sec (2.5 m/sec) Max. speed of
MXB-P 150 in/sec (3.8 m/sec).
C) For MXB-S moment and load capacities
see tables on page mxb_12.
For MXB-P moment and load capacities
see tables on page mxb_13.

CALCULATE LOAD FACTOR (LF)
For loads with a center of gravity offset
from the carrier account for both applied
(static) and dynamic loads. The load factor (LF) must not exceed the value of 1.
LF = Mx + My + Mz + Fy + Fz < 1
Mxmax Mymax Mzmax Fymax Fzmax

If LF does exceed the value of 1, consider
the four choices listed in step #2.

E STABLISH YOUR MOTION
PROFILE AND CALCULATE
ACCELERATION RATE
Using the application stroke length and
maximum carrier velocity (or time to
complete the linear motion), establish
the motion profile. Select either triangular
(accel-decel) or trapezoidal (accel-constant speed-decel) profile. Now calculate
the maximum acceleration and deceleration rates of the move. Acceleration/
deceleration should not exceed 1200 in/
sec2 (30.48 m/sec2). Also, do not exceed
safe rates of dynamic inertia moments
determined in step #3.

Calculate the application load
