Cylindrial Roller Bearings N300 Series

RunFine Cylindrical Roller Bearings are classified into Single Row Roller Bearing N300 Series

We also have bearings with cage and full complement assembly. Cylindrial Roller Bearings N300 Series with cage have high radial load carrying capacity, operating at high speed.  Single Row Roller Bearing N300 Series can accommodate even higher radial loads, but at low and moderate speed.

Cylindrial Roller Bearings N300 Series are designed to have heavy radial load- carrying capacity; rolling elements are ground to provide maximum contact with the raceway and are precisely crowned to avoid edge loading due to any shaft misalignments. Roller Bearings N300 Series are commonly separable and easy to mount and dismount.
