6700 Deep Groove Ball Bearing Series

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!
