Unmounted ball bearings consist of a ring of steel balls held by a rotating cage. The engineering of the bearing cage loaded with ball bearings allows normal and axial loading and tolerates high speed rotation.
Ball Bearing Units
These bearings may include butyl rubber seals or metal shields on one side or on both sides. Ball bearing sections may be light, extra light, thin, extra thin, max, single row or double row, and deep groove sections, chosen by product engineers based on specified equipment design considerations like thickness, speed, precision tolerances, loading, sealing, bore size, and durability.
