Feature:
- 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.
- 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 nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings.
