The product assembly includes a machined outer ring, side plate, steel balls, and a synthetic resin cage that retains the steel balls. This high-precision bearing rotates and develops finite linear motion on the shaft. The outer ring is provided with a snap ring on both sides and a wavy spring washer is provided between the snap ring and the cage to damp on the
impact acting on the cage and to prevent wear of the cage.

• Some bearings of this type are provided with a synthetic rubber seal on each side to prevent invasion of foreign matter.

• The outer ring is grooved so that the snap ring can be fitted and fixed easily.
