Single Row Cylindrial Bearings NJ300 Series are classified into single row, double row and multi-row Cylindrical Roller Bearings. We also have bearings with cage and full complement assembly. Cylindrial Roller Bearings NJ300 Series with cage have high radial load carrying capacity, operating at high speed. Full complement cylindrical roller bearings can accommodate even higher radial loads, but at low and moderate speed.
Cylindrial Roller Bearings NJ300 Series have been proven to have strong and consistent performance in the following applications: traction motors, electric motors, pumps and compressors, gear drives and speed reducers, construction equipment, table rollers for steel mills, paper making equipment and other heavy industrial machineries.
