Deep groove ball bearing is the most common type of rolling bearing. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a steel ball and a group of cage. There are two kinds of single and double row deep groove ball bearing, deep groove ball structure is divided two kinds of sealing and open structure, open refers to the bearings without sealing structure, sealing type deep groove ball into dust seal and oil seal.
Deep groove ball bearings mainly bear radial load, also can bear radial load and axial load. When the radial load is only subjected to the radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, with angular contact bearing performance, can bear large axial load, deep groove ball bearing friction coefficient is small, the limit speed is very high.
Deep groove ball bearing has the advantages of simple structure, compared with other types of easy to achieve high manufacturing accuracy, so easily into a series of mass production, the manufacturing cost is low, the use is very common. Deep groove ball bearings except basic types, there are a variety of variant structure, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber sealing ring, type deep groove ball bearings, deep groove ball bearings with large load capacity of ball filling gap, double row deep groove ball bearing.
Deep groove ball bearings are the most representative and widely used. Suitable for high speed and even high speed operation, but also very durable, no regular maintenance. This kind of bearing friction coefficient is small, extreme high speed, simple structure, low manufacturing cost, easy to manufacture high precision. Size range and variety of forms, applications in precision instruments, low noise motors, automobiles, motorcycles and general machinery and other industries, is the most widely used in the mechanical industry, a class of bearings. Mainly bear the radial load, but also can bear a certain amount of axial load.
Select bigger radial clearance axial bearing capacity increased under pure radial force when the contact angle is zero. When there is axial force, the contact angle is greater than zero. Generally use the stamping wave shape holder, the car body cage, and sometimes also use nylon.
Deep groove ball bearings installed in the shaft, in bearing axial clearance range, axial displacement can limit shaft or shell in two directions, so it can be two-way axial orientation. In addition, this type of bearing also has a certain ability to adjust the heart, when compared with the shell hole inclined 2° ~ 10° when, still can work normally, but have certain effect on bearing life. Deep groove ball bearing retainer for stamping steel ribbon cage, large bearing of the metal entity keep a car.
Deep groove ball bearings are the most commonly used. Its structure is simple, easy to use. Mainly used to bear radial load, but with the increase of bearing radial clearance, the performance has a certain angle contact ball bearing, can bear radial and axial load. When the rotating speed is higher, the thrust ball bearing is not suitable, it can also be used to bear the pure axial load. Compared with other types of bearings with the same size deep groove ball bearings, the bearing friction coefficient is small, high speed limit. But not resistant to shock, not suitable for heavy load.
