LAR Series linear rotary actuators

The SMAC LAR31 Series combines linear (moving coil) and rotary (brushless motor) motion in a single actuator. With a vacuum passage through the shaft and rotary motor, the LAR31 prevents dust build-up in the nozzle, eliminating common problems in sensitive environments.

With over 10,000 units sold and a service life of over 100 million cycles without maintenance, the LAR31 is a proven solution for demanding industrial applications. The actuator offers programmable force, position, and speed in all axes, making it ideal for IC handling, screwdrivers, high-resolution chip bonding, gauging, sorting, pick-and-place, orientation, and press operations.
