ABSTRACT:
A bearing assembly having particular usefulness as a throw-out or release bearing for a motor vehicle mechanical clutch. The bearing assembly has a cylindrical housing provided with an annular end wall engaged with, or mounted on, the flange of a bearing carrier. The non-revolving race of the bearing is engaged against the housing end wall such as to permit lateral displacement of the race relative to the housing end wall. The revolving race of the bearing supports an annular adapter having an outwardly extending flange engaged with the release fingers of the clutch mechanism. The housing is closed by an annular end cap having a flange radially extending between the end face of the revolving race and the adapter flange and provided with a seal having its lip engaged with the revolving race end face or with the back surface of the adapter flange. A second annular seal is preferably provided between the end of the adapter opposite to the flange and the surface of the housing end wall. The seals permit rotary motion between the bearing elements and transverse motion such as to allow the bearing to self-align within the housing. Preferably, spring means are disposed within the housing such as to bias the non-revolving race end face in engagement with the housing end wall, with a force sufficient to hold the surfaces in engagement but insufficient to prevent lateral motion of the non-revolving race relative to the housing.
