They are used to accommodate radial and axial loads in both directions. Ceramic balls have oil-free self-lubricating properties. Long service life, can be used in water and high-temperature environment. The speed of the ceramic ball bearing is higher than the speed of the normal bearing. Suitable for all kinds of industrial equipment, motor, wheels, office equipment and so on.
