Abstract: A linear rolling bearing element mounted to a running surface of a guide rail, includes a main body which having a rolling-element circuit for guiding the main body along a guide rail via a plurality of rolling elements, with the rolling-element circuit having a load-bearing track and a return track. The main body has opposite ends, each of the ends having formed therein a bay which is accessible through an adjacent end face of the main body. Received in each of the bays of the main body is a deflection member which has formed therein an arcuate passageway for interconnecting the load-bearing track and the return track. Disposed in the load-bearing track, the return track and the arcuate passageways is a guide system of a polymer material, for guiding the rolling elements. The guide system includes a coating which is applied through an injection-molding process in a single working step in the load-bearing track and the return track.
