Deep groove ball bearings are divided into 11 categories: open-deep groove ball bearings (60000 type), the outer ring has slots on the deep groove ball bearings (60000N), one side with a dust cover side of the outer ring with the deep groove groove ball bearings (60000-ZN), sides with a dust cover, the outer ring has slots on the deep groove ball bearing (60000-2ZN), one side with a dust cover of the deep groove ball bearing (60000-Z), with both sides dust cover of the deep groove ball bearing (60000-2Z), side with a ring of deep groove ball bearing (60000-RS ,60000-RZ), both sides with a ring of deep groove ball bearing (60000-2RS ,60000-2RZ ), deep groove ball bearings with flanged outer ring (F 60000 type), one side with a dust cover deep groove ball bearings with flanged outer ring (F 60000-Z type), two with a dust cover flange outer groove Ball Bearing (F 60000-2Z type). deep groove ball bearings are the most representative bearing, widely used. For high speed or high speed operation, and is very durable, without regular maintenance. This kind of bearing friction, high limiting speed, simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used class bearings. The main radial load, but also can withstand a certain amount of axial load. Select large radial clearance to increase the axial load capacity to withstand the contact angle of pure radial force is zero. Axial force, the contact angle greater than zero. Generally use the punch Long Cage, car solid cage, sometimes frame by nylon. Wide range of uses: gear, instruments, electrical machinery, household appliances, internal combustion engines, transport vehicles, agricultural machinery, construction machinery, engineering machinery.
