Product description 

Deep groove ball bearings are the most typical rolling bearings with  the characteristics of simply designed structures,convenience in operation and extensive applications. They are designed as non-separable  bearings. The raceways in both of the rings are in arc groove form, which can carry radical load and double directions axial load. They are of features of low friction factor, high limit rotational speed and can be applied in situations where high-rotating speed and low noise and low vibration are required. Applications of thses bearings can be found in automobiles, machine tools, motors, instruments, construction machines, railway vehicles, agricultural machines and various other special machines.
