Bearing parts are one of the parts that make up a rolling bearing, but do not include all accessories.
Bearing ring: An annular part of a radial rolling bearing with one or several raceways.
Bearing Washer: An annular part of a thrust rolling bearing with one or several raceways.
Flat Back-up Ring: A detachable essentially flat washer with its inner or outer portion serving as a rib for the outer or inner ring of a radial cylindrical roller bearing.
Inclined retaining ring (separable): A separable ring with an "L" shaped cross-section, using its outer part as a rib for the inner ring of a radial cylindrical roller bearing.
Back-up Ring: A separable ring within a roller bearing with two or more rows of rollers that is used to isolate the two rows of rollers and guide the rollers.
Stop ring: A single-mouth ring with a constant cross-section, installed in an annular groove, to position the rolling bearing axially in the housing or on the shaft.
Locking ring: A single-port ring with constant cross-section installed in an annular groove as a back-up ring to keep the roller or cage in the bearing.
Spacer: It is an annular part used between two bearing rings or bearing washers, or between two half bearing rings or two half bearing washers, so as to maintain the specified axial distance between them.
Seal ring: An annular cover composed of one or several parts. It is fixed on one ring or washer of the bearing and contacts another ring or washer or forms a narrow labyrinth gap to prevent lubricating oil from leaking out and foreign objects from intruding.
