  • Patent number: 6715920
    Abstract: A linear rolling bearing element for mounting on a running surface of a guide rail, said element having a carrier body that comprises, for a rolling element circuit, a load-bearing zone and a return channel that are parallel to a direction of movement of the carrier body while being connected to each other by two deflecting channels disposed in head pieces that are arranged on ends of the carrier body. The head pieces comprise lubricant ducts, and a rolling element guiding means in the form of a plastic coating is arranged in the load-bearing zone, the return channel and the deflecting channels. Each head-piece is formed by a cage arranged on an end of the carrier body and by a one-piece sealing plate comprising lubricant ducts, said plate being adapted to and disposed on the cage.
