Deep groove ball bearings are one of the most widely used rolling bearings. Suitable for various industrial equipment, micro motors, small rotating motors, office equipment, etc. Deep groove ball bearings have low friction, high limit speed, high cost performance and require almost no maintenance. The toughness of carbon steel bearings after quenching is better than that of chromium steel bearings. These cost-effective bearings are widely used in areas where hardness is not required.
