A bearing includes an inner race having a rotational axis and an outer
race sharing the rotational axis of the inner race. Rolling bearing
members are constrained between the inner race and the outer race. A
retention lip is provided which is adapted to maintain a peripheral
opening of a constant gauge distance between and prevent relative axial
movement of the inner race and the outer race. The gauge distance of the
peripheral opening is adapted to allow free passage of the rolling
bearing members, upon wear on the rolling bearing members reaches a
predetermined level. The bearing provides a pass or fail indication, by
falling apart when the rolling bearing members have exceeded the
predetermined level of wear.
