A bearing (211) can include a ball member (213), a race (217), and a liner (219) located on an interior surface of the race (217), the liner (219) having a first surface bonded to an interior surface of the race (217), the liner (219) having a second surface that is adjacent to the ball member (213). The bearing (211) also includes a wafer (221) 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 (219) can be calculated by comparing a measured resistance of the wafer (221) to an original known resistance of the wafer. |
