Deep groove ball bearing is the most representative rolling bearing, which is widely used. It is suitable for operation at high speed or even extremely high speed, and it is very durable without regular maintenance. This type of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy.
Deep groove ball bearing is the most representative rolling bearing, which is widely used. It is suitable for operation at high speed or even extremely high speed, and it is very durable without regular maintenance. This type of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy. The size range and methods vary widely. It is widely used in fine instruments, low-noise motors, automobiles, motorcycles and ordinary machinery industries. It is the most common type of bearing in the machinery industry. It mainly accepts radial load, but also a certain amount of axial load.
The axial load can only be increased when the larger radial clearance is selected, and the contact angle is zero when the pure radial force is accepted. When there is axial force, the contact angle is greater than zero. Generally, the pressing wave shaped stick frame is used, the solid stick frame is made by turning, and sometimes the nylon frame is also used.
After the deep groove ball bearing is installed on the shaft, the axial displacement in both directions of the shaft or housing can be limited within the axial clearance range of the bearing, so that the axial positioning can be made in both directions. In addition, this kind of bearing also has a certain self-aligning ability. When the relative shell hole is inclined by 2 '~10', it can still work normally, but it has a certain impact on the bearing life. Most of the deep groove ball bearing holders are steel plate punched wave shaped holders, and most of the large bearings are car made metal solid holders.
Deep groove ball bearing is the most commonly used rolling bearing. Its structure is simple and easy to use. It is mainly used to accept radial load, but when the radial clearance of bearing is increased, it has certain performance of angular contact ball bearing and can accept radial and axial combined load. When the speed is high and the thrust ball bearing is not suitable, it can also be used to accept pure axial load. Compared with other types of deep groove ball bearings with the same size, this type of bearing has small friction coefficient and high limit speed.
