China Ball Bearing

The principle of a ball bearing is to reduce friction and support radial and axial loads. This is achieved by using at least two races to retain the balls and transmit the loads through the balls. Usually, one of the races is held fixed. As one of the raceways rotated which causes the ball to rotate, and because the china ball bearing are rolling have a much lower coefficient of friction than if two flat surfaces is rotated against the other.
While ball bearings have lower load capacity for their size than other types of rolling element bearings, which can tolerate misalignment of inner and outer tracks. Compared with other types of bearings, ball bearing is a cost reasonable solution, due to lower production cost of balls used in the bearing.
