Deep groove ball bearing is the most common type of rolling bearing.

　　

　　The basic deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of retaining frames. There are two types of deep groove ball bearings: single-row and double-row. The structure of deep groove ball is divided into seal and open-type. The open-type refers to the bearing without seal structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof seal. Dust-proof sealing cover material is stamped by steel plate, which can only prevent dust from entering bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent grease spillover in the bearing.

　　

　　Single row deep groove ball bearing type code 6, double row deep groove ball bearing code 4. Its structure is simple, easy to use, is the most common production, the most widely used class of bearings.

　　

　　Deep groove ball bearings are mainly used to withstand radial loads, but they are also often used to withstand combined radial and axial loads. Especially when the rotating speed of mechanical equipment is very high and thrust bearing is not suitable for use, it can be used to withstand bidirectional pure axial load without maintenance during work, and it is a kind of bearing with low price and wide use. Deep groove ball bearing models are: deep groove ball bearing (60000 type); deep groove ball bearing with stop groove (60000N type); deep groove ball bearing with dust cover on one side and stop groove on the other (60000-ZN type); deep groove ball bearing with dust cover on both sides and stop groove on the outer ring (60000-2ZN type); deep groove ball bearing with dust cover on one side;（ 60000Z type; deep groove ball bearing with dust cover on both sides (60000-2Z type); deep groove ball bearing with sealing ring on one side (60000-LS type, 60000-RZ type); deep groove ball bearing with sealing ring on both sides (60000-2LS type, 60000-2RZ type); deep groove ball bearing with flange outer ring (F60000 type); deep groove ball bearing with flange outer ring with dust cover on one side (F60000-Z type). There are 11 kinds of flange outer ring deep groove ball bearings (F60000-2Z type) with dust-proof cover on both sides.

　　

　　Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, roller skates, yo-yo, etc.
