Claim 1

A bushing for receiving a pin or trunnion of a mechanism subjected to medium or moderate loads and for force-fitting into a bearing comprising, a body having an annular cross-sectional shape and an equal radial thickness throughout the length thereof for accommodating the pin or trunnion, a radially extending, outwardly directed flange on one end of said body having at least one longitudinally extending resilient portion adjacent said one end for radial outward movement by the pin or trunnion accommodated within the body and at least one longitudinally extending substantially rigid portion adjacent the other end of said body, said resilient body portion comprising at least one longitudinally extending portion of frusto-conical shape, said frusto-conical portion having a plurality of circumferentially spaced, longitudinally extending slots, said slots extending through said flange to define a plurality of resilient segments each provided at their outer ends with a portion of said flange, said flange portions being angularly disposed with respect to the longitudinal axis of said body for yielding engagement with one end of the bearing in which the bushing is mounted and with a cooperating surface on the pin or trunnion accommodated within said body to thereby eliminate axial movement between the bearing and the pin or trunnion.
