ABSTRACT:
A bearing and a method for extending the life of such bearing is disclosed. The bearing is shown to include an inner ring having first and second race channels, wherein each race channel defines first and second raceways adapted for contact with loaded rolling elements. An outer ring is shown to have third and fourth race channels, wherein each race channel defines first and second raceways adapted for contact with loaded rolling elements. A plurality of rolling elements are positioned within the race channels and are preferably oriented so that the axis of rotation of rolling elements in the first race channel is uniform and the axis of rotation of rolling elements in the second race channel is uniform. A pair of ports formed in one of the rings, each port intercepting at least one of the race channels, wherein each port has a cross-sectional area sufficient to permit the re-orientation or replacement of the axis of rotation of the rolling elements without having to remove the bearing from its installation. The rolling elements preferably are constructed such that their diameter is greater than their length. By re-orienting or replacing the rolling elements by means of the ports, the life of bearings constructed in accordance with the invention is extended without the need to disassemble either the bearing or the machine in which the bearing is installed.
