The Motion 85272 Pedestal Actuator is designed to provide a rigid steel telescoping mechanism along with a base mount in one integrated unit.
The 85272 has a 2.0" square for strength and stability. For antirotation and support, the square ground inner tube runs in four teflon impregnated bearing pads welded in the square outer tube. 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 85272 is recommended for compressive loads up to 500 lbs.
