Pedestal Actuator Standard Duty 85872

3D Model Purchase

The Motion 85872 Pedestal Actuator is designed to provide a rigid aluminum/steel telescoping mechanism along with a base mount in one integrated unit. For antirotation and support, the inner tube runs on two engineered plastic bearings.

The Motion ball screw is housed in the inner tube and driven through a 10:1 spur gear reduction in the base. Because of the integral freewheeling at stroke ends, limit switches are not required. Generally the 85872 is recommended for compressive loads up to 500 lbs.
