LSCB SUNSPEED BALL BEARING 4308-2RS

Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing and can withstand 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 bearing is the most commonly used rolling bearing. The utility model has the advantages of simple structure and convenient use. It is mainly used to bear radial load, but when the radial clearance of bearing is increased, it has certain performance of angular contact ball bearing, and can bear the combined radial and axial load. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of deep groove ball bearings with the same specifications and dimensions, this type of bearing has small friction coefficient and high limit speed. However, it is not resistant to impact and is not suitable to bear heavy load. [2] 

After the deep groove ball bearing is installed on the shaft, the axial displacement in both directions of the shaft or housing can be limited within the axial clearance range of the bearing, so the axial positioning can be made in both directions. In addition, this type of bearing also has a certain self-aligning ability. When it is inclined 2 ′~10 ′ relative to the shell hole, it can still work normally, but it has a certain impact on the bearing life.
