Pedestal Actuator Heavy Duty 85972
The Motion 85972 Pedestal Actuator is a heavy duty design to provide a rigid steel telescoping mechanism along with a base mount in one integrated unit.
The 85972 has a larger mast of 2.500" 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 85972 is recommended for compressive loads up to 500 lbs.
