Bearings generally include inner rings, outer rings, and rolling elements. The inner ring is usually fixed to the shaft and rotates together, and the outer ring is usually fixed to the machine housing for support. The inner surface of the outer ring and the outer surface of the inner ring are machined with annular grooves for the rolling elements to roll on. Lubricants are applied to the surface of the rolling elements for oiling and maintenance.
