ABSTRACT:
An internal recirculating ball screw and nut system that is easier to manufacture and more reliant by virtue of a particular configuration of the grooves on the interior of the nut or the follower. Crossback portions of select nut grooves are arranged in a manner that allows the bearing balls to recirculate by slipping over the top of adjacent thread lands of the screw, advancing and recirculating within a single 360 degree rotation within said nut. Said recirculation is accomplished solely through the design of the path of a unitary nut, without use of any ancillary devices.
