Description:
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
Suitable for all kinds of industrial equipment, micro motor, small rotary motor, office equipment and so on.
With small friction and high-limit speed, Deep Groove Ball Bearings are cost-effective and require little maintenance.
Chromium Steel (GCr15) made with heat treating, provides high and uniform hardness, good wear resistance.
Single-row, pre-lubricated, normal accuracy.

Selection Guide:Shields (Designation Suffix Z/ZZ) - High speed. Protect from dirt and debris.
Non-contact seals (Designation Suffix RZ/2RZ) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Provide better sealing effectiveness than shields. Can be operated at the same speeds as shields.
Contact seals (Designation Suffix RS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil- and liquid-resistant). Lower limit speed than Shield Bearings.
