Background

The original name single-row radial ball bearing of a deep groove ball bearing (GB/T276-2003) is one of the most widely applied rolling bearings. It features small friction resistance and high rotation speed, and can be used for bearing radial load or combined load acted simultaneously in radial and axial directions, and also can be used for bearing axial load, such as small-power motor, automobile and tractor gear box, machine tool gear box, general machine and tool, deep groove ball bearing is the most commonly used rolling bearing. It has simple structure and convenient use. The bearing is mainly used for bearing radial load, but when the radial play of the bearing is increased, the bearing has certain performance of an angular contact ball bearing and can bear combined radial and axial load. When the rotating speed is high and the thrust ball bearing is not suitable to be adopted, the thrust ball bearing can be used for bearing pure axial load. Compared with other types of bearings with the same specification and size of the deep groove ball bearing, the bearing has the advantages of small friction coefficient and high limit rotating speed. But not shock-resistant, unsuitable to bear heavy load etc. deep groove ball bearing is suitable for the operation of high rotational speed even very high rotational speed, and very durable, need not frequent maintenance, and this kind of bearing coefficient of friction is little, and the ultimate rotational speed is high, and size range and form change are various, use in industries such as precision instrument, low noise motor, car, motorcycle and general machinery, be the most extensive kind of bearing of using in the mechanical industry, mainly bear radial load, also can bear a certain amount of axial load.

A deep groove ball bearing has the following defects when in use:

the existing deep groove ball bearing has large clearance fit, and has great influence on load distribution, vibration, noise, friction, service life, mechanical motion precision and the like. By selecting a proper bearing clearance, the load can be reasonably distributed among the rolling bodies, and for this purpose, a deep groove ball bearing is provided.
