Deep groove ball bearings are widely used rolling bearings. It is characterized by low frictional resistance and high speed. It can be used on parts with radial load or combined load of radial and axial action. It can also be used for parts subjected to axial load.

The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The deep groove ball bearing types are single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without sealing structure. The sealed deep groove ball is divided into dustproof seal and oil proof. seal. The dust seal cover material is stamped from steel plate, which is simple to prevent dust from entering the bearing raceway. The oil-proof type is a contact type oil seal, which can effectively prevent the grease inside the bearing from overflowing. The single row deep groove ball bearing type code is 6, and the double row deep groove ball bearing code is 4.
