Description

Single-row, pre-lubricated, normal accuracy.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 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 nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings.
