About Cylindrical Roller Bearing

  • Cylindrical roller bearings feature high radial load capacity because the rollers and raceway are in linear contact.
  • These bearings are suitable for applications that involve heavy radial and impact loading.
  • They are also appropriate for high-speed applications in that they can be machined very accurately due to their structure.
  • Having a separable inner ring or outer ring, these bearings can be mounted and dismounted easily.
  • The geometry allows for accurate machining to precision grade quality and uses at high speeds.
  • The inner or outer rings can be separated, simplifying mounting and removal of the bearing.

Single-row Cylindrical Roller Bearings

  • The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft's axial movement, to a certain extent, relative to the housing position.
  • The NJ and NF types carry axial load in one direction, while the NUP and NH types can carry a certain degree of axial load in both directions.
  • Type R cylindrical roller bearings feature enhanced load ratings compared with standard series, though both have equal dimensions.
  • This is because type R bearings have a different internal design.
  • They are identified by supplementary code "R".

Main Applications

  • Automotive: Internal combustion engines transmissions, and cargo transportation
  • Electrical: Large and medium sizes motors, traction motors, and generators
  • Industrial: Gearboxes and machine tool spindles, steel mills
