Linear rolling bearing element

A linear rolling bearing element mounted to a running surface of a guide rail, comprising:

• a main body which includes a rolling-element circuit for guiding the main body along a guide rail via a plurality of rolling elements, said rolling-element circuit having a load-bearing track and a return track, said main body having opposite ends, each end having formed therein a bay which is accessible through an adjacent end face of the main body;
• two deflection members, one of the deflection members completely and detachably received in the bay at one end of the main body and the other one of the deflection members completely and detachably received in the bay at the other end of the main body, each deflection member having formed therein an arcuate passageway for interconnecting the load-bearing track and the return track;
• and
• guide means, disposed in the load-bearing track and the return track and made of a polymer material, for guiding the rolling elements, said guide means including a coating applied through an injection-molding process in a single working step in the load-bearing track and the return track, wherein the guide means includes an extension piece disposed at the end of the main body and formed integrally with the coating for circumscribing the bay.
