Abstract
A ring is telescoped into the end of a nut of a ball screw and nut assembly and carries a lip which breaks ice away from the screw. The plastic insert of relatively short circumferential length is supported by the ring and is urged into the groove of the screw by a spring so as to wipe mud from the screw. A felt strip coacts with the insert to seal the nut against the entry of foreign particles and to restrict the escape of lubricant from the nut.
