MXB-P Actuators

The MXB-P has a profiled rail that guides the carrier across the entire extrusion for high load capability.

The MXB is Tolomatic’s most advanced belt driven linear actuator series, with 3 different carrier guide options: Unguided (U), Solid Bearing (S), and Profiled Rail (P). The Profiled Rail carrier provides the highest load support and rigidity of the MXB series. The recirculating ball bearing linear guides allow for long operation life, easy maintenance, and high speed travel.

TEMPERATURE RANGE -12 to 54 °C 10 to 130 °F
Heat generated by the motor and drive should be taken into consideration as well as linear velocity and work cycle time. For applications that require operation outside of the recommended temperature range, contact Tolomatic.

STRAIGHTNESS, FLATNESS 0.01702 L mm 0.00067 L in
Actuator mounted on a flat surface and fully restrained (see Mounting Plate Requirements, MXB catalog 8500-4000 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.
