BEARING

The INA Bearing Co., Inc. has introduced a maintenance-free spherical plain bearing. The bearing is claimed to remain free of radial clearance in operation in spite of wear. The main characteristic of the bearing is a plastic outer ring with several slot on one side which extend over the center line. The slots are used to remove any radial clearance by applying pressure from the OD. To eliminate bearing clearance, the outer ring has a groove in the slotted area which contains an O-ring. The groove is just deep enough so that the outside diameter of the O-ring extends beyond the outside diameter of the outer ring. When mounted into a housing bore of proper diameter, the compressed O-ring acts like a spring and forces the outer ring segment against the inner ring, thus eliminating any bearing clearance.
