A bearing pin for simple, reliable attachment to a support. A bearing sleeve is pressed over a knurled surface of a pin which is fastened to the support. To prevent movement of the pin with respect to the support, the pin has a support engaging surface forming an edge with the knurled surface. The knurling is continued up to that edge, so that pin material is upset axially beyond the support engaging surface. Upon fastening of the pin to the support, the axially upset material bites into the surface of the support to prevent rotation of the pin. This same knurling, or alternative upset pattern, prevents relative movement between the bearing sleeve and the pin.

A bearing pin comprising a pin made of a pin material, and a bearing bushing, for attachment to a supporting element, said pin having a mounting end surface having a perimeter edge; a bushing-engaging surface extending away from said edge of the end surface, said bushing being tightly fitted around said bushing-engaging surface; and means for securing the pin to a supporting element with at least a portion of said end surface engaging the supporting element, characterized in that said bushing-engaging surface has a pattern of upset features formed therein for engaging the bushing to prevent relative motion between the pin and the bushing, said pattern extending to said edge such that portions of the pin material are upset axially beyond said perimeter edge and said bushing, for locking the pin against relative movement with respect to the supporting element.
