The 238tVL304 Thrust angular contact ball bearings are mainly composed of precision-ground steel balls, hardened and ground steel raceways, and a brass (or bronze) cage. Their core characteristic is their ability to simultaneously withstand axial thrust loads and a certain amount of radial load, and they also feature low friction, quiet operation, and suitability for high-speed operation.
