LEFS Electric Actuator, Slider Type, Ball Screw Drive

LEFS Electric Actuator, Slider Type, Ball Screw Drive Show Description

The original LEFS slider features an inline motor with a cover. Because the motor drives the ballscrew directly, additional cost of a belt and pulley system is avoided. The motor cover is taller than the load platform, so be aware of potential interference at the origin position.
