ABSTRACT:
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.
