Working principle of deep groove ball bearing

Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load at the same time. When it only bears radial load, the contact Angle is zero. When deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the limit speed is also very high.

Deep groove ball bearing is the most representative rolling bearing, widely used. Suitable for high speed or even extremely high speed operation, and very durable, no frequent maintenance. This kind of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy. It is widely used in precision instrument, low noise motor, automobile, motorcycle and general machinery and other industries. It is the most widely used kind of bearing in machinery industry. Mainly bear radial load, can also bear a certain amount of axial load.

The axial bearing capacity is increased when the radial clearance is larger, and the contact Angle is zero when the pure radial force is borne. With axial force, the contact Angle is greater than zero. Generally used stamping wave cage, vehicle solid cage, sometimes also used nylon. After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or the shell in both directions can be limited within the axial clearance range of the bearing, so the axial positioning can be made in both directions. In addition, this kind of bearing also has a certain aligning ability, when the Angle is 2 '~10' relative to the shell hole, it can still work normally, but it has a certain impact on the bearing life. Deep groove ball bearing cage is mostly steel plate stamping wave cage, large bearings are mostly made of car metal solid cage. Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing, and can bear the combined diameter and axial load. When the speed is higher and it is not suitable to use thrust ball bearings, it can also be used to bear pure axial load. Compared with other types of bearings with the same size of deep groove ball bearings, the friction coefficient of this kind of bearings is small and the limit speed is high. But not impact resistant, not suitable for heavy load.
