The deep groove ball bearing is a kind of rolling bearing with most representatives, and it has features of small friction coefficient, high limiting speeds, simple structure, low cost, and high manufacturing precision. It has various sizes and structures, and is used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, and a kind of bearing with most applications in the machinery industry. The bearing can bear mainly the radial load, but also can bear a certain axial load.

With larger radial clearance, the axial carrying load can be increased. When it only bears the radial load, the contact angle should be zero; when it bears an axial load, the contact angle should be greater than zero. A stamped ribbon cage is commonly machined as the solid cage; sometimes the nylon cage can also be used.
