Zusammenfassung:A lubricated guide unit is for a motorcycle fork tube that includes an outer tube and an inner tube telescopically slidable within the outer tube. The guide unit includes upper and lower sliding bushings axially spaced apart and disposed within a cavity of the outer tube and guide sliding movement of the inner tube. A first sealing device is mounted at an open end of the outer tube and seals against the outer surface of the inner tube. A second sealing device is mounted in the outer tube and seals against the outer surface of the inner tube. The second sealing device is axially spaced from the first sealing device such that a sealed, lubrication chamber is defined between the two sealing devices and the facing circumferential surfaces of the inner and outer tubes, the two bushings being disposed within the chamber.
