Please look at the picture and select the correct bearing type before placing your order (sealed or shielded on both or single sides of the warehouse). Suffix in stock only for distinguishing between sealed and shield type of bearing. It does not affect the use of our product.



Description:


Deep groove ball bearings are one of the most commonly used rolling bearings.
Suitable for all kinds of industrial equipment, micro motors, small rotary motors, office equipment and so on.
With low friction and high limit speed, deep groove ball bearings are cost-effective and require little maintenance.
Carbon steel bearings have better toughness after hardening than chrome steel bearings. These low cost bearings are commonly used in areas with low hardness requirements.
Single row, pre-lubricated, normal accuracy.



Selection guide:

Cover discs (designation suffix Z/ZZ) - High speed. Protects against dirt and debris.

Sealed (designation SuffixRS/2RS) - Made of sheet steel reinforced nitrile butadiene rubber (oil and liquid resistant). Lower limit speed than shield bearings.
