Sealed deep groove ball bearing often adopts steel skeleton rubber sealing ring. It adopts a contact seal compared with the deep groove ball bearings with dust cover. The product has better dustproof and waterproof performance. But it has larger friction resistance and limited speed with certain restrictions. Our product mainly support radial load and can also bear a certain amount of axial load.

Sealed deep groove ball bearing is one of the most representative rolling bearings which is applicable to high speed or even superhigh speed operation. It is very durable without frequent maintenance and has simple structure, and comes with low manufacturing cost and higher manufacturing precision. Our product is widely used in the precision instrument, low noise motor, automobile, motorcycle and general machinery industry.
