Self reversing screw

The self-reversing screw product does not require the driven screw to change its direction of rotation to enable the nut to return to its original start position. The reciprocated bi-directional movement is achieved by using a follower blade in the nut, that is matched to the particular groove width and screw turn round on the screw.
