Motorized Lead Screw Actuators MLA

Thomson Industries introduced its MLA motorized lead screw actuators featuring built-in anti-rotational guidance.

The design eliminates the need for external guidance by surrounding the shaft with an aluminum cover tube with molded internal splines that lock onto the nut to keep it from turning. This design also features an integrated bushing that enables it to withstand small radial and moment loads.

The actuator configuration provides simple integration into any assembly with a range of end mounting and connection options.

These motorized lead screw actuators are best suited for space-constrained, force-sensitive applications requiring shorter strokes that must be repeated with high precision. Ideal applications have stroke lengths shorter than 2.5 inches; have loads lighter than 200 lbf on various motor sizes; and require speeds below 20 in/s.

They are available for NEMA 8, 11, 14, 17 and 23 motor frame sizes; in single or double stacks; with many motor winding options. Linear resolution options range from 0.063 to 7.5 µin of linear travel per step.
