An improved self-centering bearing assembly for clutch release mechanism includes a radial bearing with a rotatable inner and non-rotatable outer race. The outer race is resiliently held for radial self-centering movement by an attachment member which mounts the bearing assembly to a plastic carrier of the clutch release mechanism. The resilient element that allows self-centering is compressed between a radial flange of the attachment and a face of the outer race. When removed from the carrier, the resilient element expands sufficiently to bias the radial flange into a radially extending portion of a declutching finger contacting member rigid to the inner race. This retains the attachment member to the bearing as a separately handled, rattle-free unit. The spacing between that portion of the contact member and the face of the outer race against which the resilient element bears is small enough not only to allow unitization, but also small enough that when the resilient element of the mounted bearing assembly is compressed, the resulting gap between that portion of the contact member and the radial flange is just sufficient to allow relative rotation of the races, so that the bearing is shielded. Therefore, the extension of the contact member has both a retention and a shielding function in cooperation with structure already present for other purposes.
