ABSTRACT:
A method of forming an internal conical surface on the counterbore of an annular antifriction-bearing locking collar is disclosed which comprises the steps of providing one end of the collar with a counterbore having a circumferential side wall, and deforming relative to the axis of the counterbore at least a portion of the periphery of the counterbore by forcing a corresponding portion of the circumferential side wall of the counterbore generally radially inwardly to thereby form the internal conical surface on the counterbore.
