ABSTRACT:
A bearing unit for a rotating component, such as a toothed gear or guide pulley, with an integrated pump consists of a housing with a pump chamber defined therein, a pump rotor installed in the pump chamber, a support pin having an end supported in the housing, and a bearing ring rotatably mounted on the support pin. The bearing unit is mountable on a support surface of an associated machine element, such as an engine block by means of a flange on the housing. The pump rotor and the rotating component are securely mounted on the outer surface of the bearing ring in mutual abutting relationship. The pump rotor is disposed between the housing flange and a web portion of the rotating component. The rim portion of the rotating component circumscribes the pump rotor. A sliding sealing ring is provided between the housing or housing ring and the rotating component.
