Cylindrical Roller Bearing

  • Cylindrical Roller Bearing
  • Cylindrical rollers and raceways are linear contact bearings, with large load capacity, mainly bearing radial loads. The friction between the rolling element and the ring flange is small, which is suitable for high-speed rotation. According to whether the ring has any edge, it can be divided into NU, NJ, NUP, N, NF and other single-row bearings, and NNU, NN and other double-row bearings.The bearing has a separable inner and outer ring structure. Cylindrical roller bearings with no ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free-end bearings. Cylindrical roller bearings with double ribs on one side of the inner and outer rings and a single rib on the other side can bear axial loads in one direction to a certain degree. Steel stamped cages or copper alloy car cages are generally used. However, some use polyamide molding cages.
