Bearing Characteristics Of Deep Groove Ball Bearings
- Aug 01, 2017 -

Deep groove ball bearings are the most representative of rolling bearings, widely used. Suitable for high speed or even very high speed operation, and very durable, without regular maintenance. The friction coefficient of this kind of bearing is small, the limit speed is high, the structure is simple, the manufacturing cost is low, and it is easy to achieve high manufacturing precision. The size range and form variety, applied in the precision instrument, low-noise motor, automobile, motorcycle and general machinery industry, is the most widely used in the mechanical industry bearings. The main bearing radial load, can also withstand a certain amount of axial load.

When the large radial clearance is selected, the axial load capacity is increased, and the contact angle is zero when the pure diameter force is subjected. When there is axial force, the contact angle is greater than 0. The general use of stamping wave-shaped cage, vehicle-solid cage, and sometimes the use of nylon frame.

After the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or shell can be restricted in two directions in the axial direction of the bearing, so the axial orientation can be made in two directions. In addition, this kind of bearing also has certain adjustment ability, when relative to the shell hole inclined 2′~10′, still can work normally, but has certain influence to the bearing life. Deep groove ball bearing cages for steel plate stamping wave-shaped cage, large-scale bearings are used in the car metal solid cage.

Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. Mainly used to withstand radial load, but when increasing the radial clearance of bearings, with a certain angular contact ball bearing performance, can withstand the diameter, axial joint load. When the rotational speed is high and the thrust ball bearing is not suitable, it can also be used to withstand the pure axial load. Compared with other types of bearings with the same size as the deep groove ball bearings, the friction coefficient of this kind of bearing is small and the limit speed is high. But not withstanding the impact, not suitable for heavy load.
