ABSTRACT:
The axial bearing includes a first ring and a second ring. During operation of the axial bearing, the first ring rotates with respect to the second ring. Over time the foregoing rotation produces wear of the first ring; consequently, exposes layers of the first ring to the second ring. The different layers of the first ring produce variations in the coefficient of friction within the axial bearing. If the axial bearing is associated with a drive motor, then the variations in the coefficient of friction change the load on the drive motor. The change in load upon the drive motor may be monitored to indicate axial bearing wear or the need for axial bearing replacement.
