Learn about thin wall ball bearings in 1 minute!

Thin wall ball bearings:
Deep groove ball bearings: 6900, 6800, 6700, 618, 619 series are thin wall bearings.
In addition, there are many thin wall ball bearings with different names in other countries. 
Thin wall angular contact ball bearings: 718 and 719 series are also thin wall bearings.

Thin wall ball bearings have a bearing inner diameter and outer diameter ratio less than a specified value. The ratio of bearing outer diameter to bearing inner diameter is 1.25 or less. It is called thin wall ball bearings, which means that the outer diameter-inner diameter value of the bearing is very small and the bearing wall is very thin.
The precision required by thin wall ball bearings is very high, because the wall is very thin, so the weight it can carry is also very low, and the impact resistance is very poor, so this must be selected according to the use environment!

Characteristics
Thin wall ball bearings are simple in structure and easy to use. 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 combined radial and axial load.
When the speed is high and thrust ball bearings are not suitable, thin wall ball bearings can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for heavy loads.
The specific use of thin wall ball bearings:
Model airplanes, remote control cars, machine tools, motors, water pumps, agricultural machinery, textile machinery, laser printers, instruments, measuring instruments, electronic accessories, motors, motors, etc.
