Abstract
A bearing can include a ball member, a race, and a liner located on an interior surface of the race, the liner having a first surface bonded to an interior surface of the race, the liner having a second surface that is adjacent to the ball member. The bearing also includes a wafer having a wear surface that is aligned with the second surface of the liner, the wafer being an electrically conductive member. Operational wear of the liner can be calculated by comparing a measured resistance of the wafer to an original known resistance of the wafer.
