The basic introduction of deep groove ball bearings

Deep groove ball bearing is the most representative rolling bearing. For high and extremely high speed work, very durable and does not require frequent maintenance. The friction coefficient of deep groove ball bearing is small, the limit rotation speed is high, the structure is simple, the manufacturing cost is low, and it is easy to achieve high manufacturing accuracy. The range of size and structure types are varied, widely used in precision instruments, low noise motors, all kinds of automobiles, motorcycles and common machinery and other industries, is the most widely used type of bearing in the machinery industry. Usually can bear radial load, may also bear a certain amount of axial load.

Deep groove ball bearings are frequently selected rolling bearings. The structure of deep groove ball bearing is simple and easy to use. It is usually used to withstand radial loads, but when the radial clearance of the bearing is increased, there is a certain function of angular contact ball bearings, and it can also withstand the combined radial and axial loads. When the rotation speed is high and it is not suitable for selecting thrust ball bearings, it is also used to withstand pure axial load. Compared with other types of bearings with similar specifications and sizes of deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit rotation speed. However, it is not shock resistant and should not be able to withstand heavy loads.

The deep groove ball bearing is installed on the shaft, and within the range of the axial clearance of the bearing, the axial displacement of the shaft or the housing in two directions can be limited, so that the axial positioning can be done in both directions. It is worth mentioning that the deep groove ball bearing has a certain aligning ability, when the relative tilt to the shell hole 2 '~10', it can still work normally, but it has a certain impact on the bearing life. Most of the deep groove ball bearing retainers are steel plate stamping wave retainers, and large bearings choose machined metal solid retainers.

Several categories of deep groove ball bearings are single row deep groove ball bearings, single row deep groove ball bearings with dust cover, single row deep groove ball bearings with dust cover, sealing ring, single row deep groove ball bearings with a stop groove and stop ring on the outer ring, deep groove ball bearings with ball notches, double row deep groove ball bearings and so on there are many types, there are different models.
