Abstract

A rolling bearing for lengthwise movement on a shaft (6) has a cage assembled in the bore of a housing surrounding the shaft. The cage has at least one longitudinally extending guide slot extending radially therethrough and a rail supported in the bore of the housing and outwardly covering the guide slot. The rolling bodies, which are inserted in the guide slot of the cage, are arranged to run serially in rows between the longitudinally directed races of the rail and shaft. In order that the rolling body for lengthwise movement can withstand the greatest load forces in the angular deviation and bending of the shaft, the rail consists of at least two partial rails individually tiltably supported in the bore of the housing and arranged adjacent one another in the lengthwise direction.
