Self-aligning clutch bearing assembly

A clutch release bearing assembly comprising a first race member defining a first annular raceway and including means defining an annular engaging surface for contacting external clutch release members, a second race member defining a second annular raceway and including means for engaging actuating means for effecting axial shifting movement of said bearing assembly, a plurality of antifriction bearing elements interposed between said first and said second race member and riding in the annular raceways thereof, said second race member formed with a bore extending axially therethrough for receiving a generally cylindrical support member in a radially spaced clearance relationship defining an annular clearance space therebetween, said bearing assembly adapted to be mounted on the support member and a resilient polylobate spring disposed in encircling relationship within said annular clearance space between said bore and the periphery of the support member for supporting said bearing assembly and said annular engaging surface on the support member in yieldable spaced relationship to permit limited deflection of said engaging surface in a plane perpendicular to and in planes angularly tilted with respect to the axis of said support member.
