Deep groove ball bearings are suitable for high speed operation and are very durable. This type of bearing has a small friction coefficient and is used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery and other industries. It is the most widely used type of bearings in the machinery industry. It mainly bears radial load, and can also bear a certain amount of axial load.

Due to its wide range of use, it is easy to be immersed in dust and water, causing rust to affect the speed. So the manufacturer created the sealed deep groove ball bearing. Sealed deep groove balls are divided into iron sheet sealing and rubber sealing.

Rubber-sealed deep groove ball bearings can effectively prevent external dust and water stains from entering the bearing raceway and reduce the speed caused by rusting of the bearing. And the rubber sealed deep groove ball bearing is not as easy to rust as the iron deep groove ball bearing, so it is loved by many people .
