Deep groove ball bearings are suitable for running at high or even very high speeds and are very durable, requiring no frequent maintenance. This kind of bearing has small friction coefficient, high limit speed, varied size range and form, and is used in precision instrument, low noise motor, automobile, motorcycle and general machinery industries, etc. It is the most widely used type of bearing in the mechanical industry, mainly bearing radial load, also bearing a certain amount of axial load.

Deep groove ball bearing is the most common type of rolling bearing. The deep groove ball bearing of the basic type consists of an outer ring, an inner ring, a group of steel balls and a group of retainers. There are two types of deep groove ball bearings: single row and double row. Deep groove ball structure is also divided into two types: sealed and open. Dustproof sealing cover material for the steel plate stamping only plays a simple role to prevent dust into the bearing raceway. The anti-oil type is contact oil seal, which can effectively prevent the grease inside the bearing from spilling out.

Single row deep groove ball bearing type code for 6, and double row deep groove ball bearing code for 4. It has simple structure and is easy to use, which is the most common production and the most widely used type of bearings.
