    The cylindrical roller and raceway are linear contact bearings. The load capacity is large, mainly bearing radial load. The friction between the rolling body and the retaining edge of the ferrule is small, which is suitable for high-speed rotation. According to whether the ferrule has a flange, it can be divided into Nu, NJ, NUP, N, NF and other single row cylindrical roller bearings, NNU, NN and other double row cylindrical roler bearings. The bearing is a separable structure of inner ring and outer ring.
