Stepper Motor Linear Actuators - MLA

Thomson motorized lead screws are also available in an actuator configuration (MLA). The actuator is a fully housed solution – simply determine stroke length, linear travel per step or revolution (lead), and precision level to select an appropriate MLA. The actuator configuration offers a complete housing and integrates easily into your assembly with a selection of end mounting and connection options.

The actuator is a fully housed motorized lead screw with a rotating screw configuration. The bushing design included inside the assembly, highlighted above, gives the actuator built-in anti-rotation and side load capability.

The built-in anti-rotation comes standard with every MLA. Anti-rotation may eliminate the need for external guidance.

MLAs are able to withstand some side and moment loading. Depending on load, speed and motion requirements, MLA assemblies can withstand a side load of up to 10% of axial capacity of the motor. For optimal performance, side and moment loads on MLA configurations should be minimized and avoided in the fully extended position.
