• High linear velocity
• High acceleration rates
• Long stroke lengths
• Longer stroke length than
screw drive actuators
• Excellent repeatability
• High duty cycles
• Low profile • Lowest profile
• Requires external guidance
and support
• High load and bending moment capacities
• Superior rigidity, high moment
loads
• High precision bearings
feature smooth, low breakaway motion
• Straightness and flatness
within 0.0002 inches per inch
of stroke
• Durable profiled rail design
uses THK®
Caged Ball®
technology to reduce friction
and extend actuator life
• Wide stable platform for XY
applications
• Lowest carrier deflection of
any Tolomatic actuator

The MXB
electric actuator
is exactly what you
expect from the indus-
try’snumberonerodlesssup-
plier. Designed with our exclu-
sive ENDURANCE TECHNOLOGYSM
features, the MX delivers superior per-
formance to meet the most demanding
applications. The MXB broadens the choices
for belt drive actuators providing Tolomatic reliabili-
ty in applications that were not available before. Nobody
knows rodless like Tolomatic, and the MX proves it.
Use these graphs for a quick reference comparing the
performance features of the MXB to the Tolomatic B3W
and TKB. For complete information about the B3W or the
TKB visit our web site or check out the B3W brochure and
the Electric products catalog.

Motor Mounting
The MXB is unique among Tolomatic belt drive actua-
tors. 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 actua-
tor is reserved for mounting. If the motor is mounted in the
SDT direct drive top orientation be sure the load mounted
to the carrier does not interfere with the motor.

COMPARISON OF MXB AND B3W
The MXB and the B3W have many similarities, yet each have
unique capabilities that suit different applications.
Note the actuators that use the same belt and pulley:
MXB25 = B3W10 MXB40 = B3W15 MXB50 = B3W20
This results in the same thrust.
