Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions. With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance. Carbon Steel bearings are better in toughness than chrome steel bearings after quenching. These cost-effective bearings are widely used in areas with low requirements for Mohs hardness. Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on. Selecting Guide: Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris. Sealed (Designation Suffix RS/2RS) - Made of sheet steel reinforced NBR (oil- and liquid-resistant). Lower limit speed than Shield Bearings.
