FAG Deep Groove Ball Bearing working principle

Deep groove ball bearings mainly bear radial loads, but can also bear both radial loads and axial loads. When it is only subjected to radial loads, the contact angle is zero. When deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the limit speed is also very high. Deep groove ball bearings There are two types of bearings: single row and double row. The single row deep groove ball bearing type is coded 6, and the double row deep groove ball bearing type is coded 4.

FAG Deep Groove Ball Bearing Bearing characteristics

Deep groove ball bearings are the most representative rolling bearings and are widely used. It is suitable for high-speed or even extremely high-speed operation, and is very durable and does not require frequent maintenance. This type of bearing has small friction coefficient, high limit speed, simple structure, and is easy to achieve high manufacturing accuracy. The size range and form vary, and they are used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery industries. They are the most widely used type of bearings in the machinery industry. It mainly bears radial load and can also bear a certain amount of axial load.

When a larger radial clearance is selected, the axial load-bearing capacity increases, and the contact angle is zero when subjected to pure radial force. When there is an axial force acting on it, the contact angle is greater than zero. Generally, stamped corrugated cages, machined solid cages, and sometimes nylon cages are used.

After the FAG Deep Groove Ball Bearing is installed on the shaft, it can limit the axial displacement of the shaft or housing in both directions within the axial clearance range of the bearing, so it can be axially positioned in both directions. In addition, this type of bearing also has a certain degree of alignment ability. When tilted 2′ to 10′ relative to the housing hole, it can still work normally, but it will have a certain impact on the bearing life. Deep groove ball bearing cages are mostly steel plate stamped corrugated cages, and large bearings mostly use machined metal solid cages.

Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial loads, but when the radial clearance of the bearing is increased, it has certain performance of angular contact ball bearings and can bear combined radial and axial loads. When the rotation speed is high and it is not suitable to use thrust ball bearings, it can also be used to bear pure axial load. Compared with other types of bearings with the same specifications and dimensions as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for bearing heavy loads.
