A ball bearing assembly (12A) has a spacer (14) to prevent ball bearing failures. The spacer (14) has a ring (22) with a tongue (34) that fits into a groove (36) in a second spacer ring (28). One spacer ring (22) is coupled to the outer ring (16A) of the ball bearing assembly (12A) and the other spacer ring (28) is coupled to the inner ring (18A) of the ball bearing assembly (12A). The spacer (14) therefore allows relative rotation of the rings (16A,18A) of the ball bearing assembly (12A) but prevents relative translation of the rings (16A,18A) beyond a point which will damage the ball bearing assembly (12A). <IMAGE> |
