Single Row Cylindrical Roller Bearings

NJ228EM

The cylindrical roller bearing has a linear contact between the rollers and the raceway, therefore, it has a high radial load bearing capacity, which enables this bearing to withstand heavy loads and impact loads well. In addition, since the inner and outer rings can be separated, it is easy to disassemble and assemble.
