Deep Groove Ball Bearing

Deep groove ball bearings are the most common type of rolling bearings.
The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of retaining frames. There are two types of deep groove ball bearings: single row and double row, and the deep groove ball structure is also divided into two structures: sealed and open, open means that the bearing does not have a sealed structure, and the sealed deep groove ball is divided into dustproof seal and oil-proof seal. The dust seal cover is made of steel stamping, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from escaping.
The type code for single row deep groove ball bearings is 6, and the code for double row deep groove ball bearings is 4. Its structure is simple, easy to use, is the most common production, the most widely used type of bearing.
How it works
Deep groove ball bearings are mainly subjected to 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 the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing, can bear a large axial load, the friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high.
Bearing characteristics
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 load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing, and can bear the combined load of radial and axial directions. When the speed is high and thrust ball bearings are not suitable, they can also be used to bear pure axial loads. 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 ultimate speed. However, it is not resistant to impact and is not suitable for bearing heavy loads. [2]
When the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or housing can be limited within the axial clearance range of the bearing, so that it can be positioned axially in both directions. In addition, this kind of bearing also has a certain self-aligning ability, when it is inclined to 2′~10′ relative to the bore of the shell, it can still work normally, but it has a certain impact on the bearing life.

Bearing construction
Deep groove ball bearings have a simple structure and are easy to achieve high manufacturing accuracy compared with other types, so they are convenient for mass production in series, and the manufacturing cost is also low, and they are extremely commonly used. In addition to the basic type, there are various variant structures of deep groove ball bearings, such as: deep groove ball bearings with dust covers, deep groove ball bearings with rubber seals, deep groove ball bearings with stop grooves, deep groove ball bearings with large load capacity with ball notch, and double row deep groove ball bearings
