Clutch thrust bearing

In a self-centering clutch thrust bearing having a central axis and including inner and outer races, a plurality of rolling elements between said races, a sliding sleeve having at least a first annular part thereof situated radially inward of said inner race, said first annular part and said inner race having first and second facing surfaces, respectively, with an annular space defined therebetween, said sleeve being slightly movable radially relative to said inner race, thus defining radial play therebetween, and coupling means engaging and maintaining said sleeve and inner race in generally fixed axial relationship, the improvement in combination therewith comprising an elastic ring situated in said annular space on one of said first and second surfaces, the ring having resilient lugs extending toward the other of said surfaces for resiliently engaging the other of said surfaces during relative radial displacement therebetween, and thereby damping relative radial movement between said sleeve and inner race.
