Ball bearing is a metal component. It consists of steel balls fixed in a cage within an inner race. Moreover, it is used to compensate radial and axial loads. Also, Ball bearings provide very low friction. But have a limited load-carrying capacity. This is a direct result of the little territory of contact between the balls and the races.
