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 group of steel balls and a group of cages.There are two types of deep groove ball bearings: single row and double row. The single row deep groove ball bearing type is 6, and the double row deep groove ball bearing type is 4. Its structure is simple, easy to use, is the most common production, the most widely used class of bearings.
Working principle

　　Deep groove ball bearing mainly bears radial load, can also bear radial load and axial load at the same time. When it is only under radial load, the contact Angle is zero. When the deep groove ball bearing has a larger radial clearance, it has the performance of angular contact bearing and can withstand larger axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is very high.

Type of bearing

1. Single row deep groove ball bearing

2. Single row deep groove ball bearing with dust cover

3. Single row deep groove ball bearing with dust cover and sealing ring

4. Single row deep groove ball bearings with stop groove and stop ring on the outer ring

5. Deep groove ball bearing with ball filling gap

6.Double row deep groove ball bearings

Characteristic of bearing

Deep groove ball bearing is the most representative rolling bearing, widely used. Suitable for high and even extremely high speed operation, and very durable, no frequent maintenance. This kind of bearing has small friction coefficient, high limit speed, simple structure and easy to achieve 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 type of bearing in the machinery industry. Mainly bear radial load, can also bear a certain amount of axial load.

When the radial clearance is larger, the axial bearing capacity increases and the contact Angle is zero when the pure radial force is borne. With axial force, the contact Angle is greater than zero; Generally use ram wave cage, car solid cage, sometimes also use nylon frame.

After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or the shell in two 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 relative to the shell hole tilt 2 '~ 10', it can still work normally, but it has a certain impact on the bearing life. Deep groove ball bearing cages are mostly steel plate stamping wave cages, large bearings are mostly made of metal solid cages.

Deep groove ball bearing is the most commonly used rolling bearing. 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 radial and axial load. When the speed is higher and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same size and specification of deep groove ball bearings, such bearings have small friction coefficient and high limit speed. But not impact resistant, not suitable to bear heavy loads.
