Abstract

A linear recirculating anti-friction bearing assembly is disclosed for movably supporting a workpiece on a support shaft in the form of a round way. The bearing includes a housing and an elongate inner roller race for supporting the work piece on the round way. A plurality of rollers are positioned within the housing and are recirculated between loaded positions between the inner race and the round way and unloaded positions through which the rollers are recirculated back to the loaded positions. The housing is configured to retain the rollers and includes roller retainer strips at the lower end portions adjacent the inner race to retain the rollers in position when supporting the housing on the round way and to retain lubricants within the housing. Additional dust/lubrication means are provided on the housing.
