Anti-rotation device

Characteristics

When work screw rotation must be prevented, the jcks can be realized with keyway along the work screw, a matching key is fastened to the cover of the jack which will eliminate work screw rotation. Anti-rotation device is suggested for limited strokes and low speed. The anti-rotation device causes greater than normal wear on the work screw, somewhat reducing jack life.
