C3 oil gap bearings are suitable for the following occasions,
The temperature difference between the inner and outer ring is large, bear a large load or need to improve the self-aligning performance。

C0 oil gap is suitable for the following occasions,
The rotation accuracy is high, or the axial displacement needs to be strictly controlled.

Features:

1. 6307-2Z/C3 is single row deep groove bearing, it has a straight forward design which is robust in operation and easy to maintain.
