Bearing housing for use in wheel of car, has sealing device comprising annular lips staying in frictional contact with respective inner and outer annular walls by exerting contact pressure with axial component and radial component

摘要

The housing has an inner member (1) and an outer member (2) arranged opposite to each other to realize a raceway (4) in which rolling bodies (5) are arranged. The bodies are retained by a cage (6), where the raceway opens into an annular space (8) bounded by an inner annular wall (9) and an outer annular wall (10). An annular space is provided with a sealing device with annular lips (11-14) that rotate with the cage for retention of the bodies. The lips stay in frictional contact with the respective walls by exerting contact pressure with an axial component and a radial component.
