The cylindrical roller and the raceway are linear contact bearings.Large load capacity, mainly bear radial load.The friction between the rolling body and the ring edge is small, which is suitable for high speed rotation.According to the ring with or without flange, it can be divided into NU, NJ, NUP, N, NF and other single row cylindrical roller bearings, and NNU, NN and other double row cylindrical roller bearings.The bearing is a structure with separable inner and outer rings.The cylindrical roller bearings with inner or outer rings without flanges can be used as free-end bearings because the inner and outer rings can move relative to each other in the axial direction.One side of the inner ring and outer ring is provided with double flaps, and the ring on the other side is provided with a cylindrical roller bearing with a single flaps, which can withstand a certain degree of axial load in one direction.Generally, steel plate stamping cages are used, or solid cages made of copper alloy cars

 

Bearing characteristics

  1. Roller and raceway for line contact or repair line contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.
  2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.
  3. Type N and NU can be moved axially, which can adapt to the change of relative position between shaft and shell caused by thermal expansion or installation error, and can be used as free end support.
  4. The processing requirements for the shaft or seat hole are high. The relative deviation of the outer ring axis should be strictly controlled after the installation of the bearing to avoid the concentration of contact stress.
  5. The inner or outer ring can be separated for easy installation and disassembly.

 

Bearings characteristics

Cylindrical roller and raceway line contact, radial load capacity is large.It is suitable for bearing heavy load and impact load as well as high speed rotation.

SKF Cylindrical roller bearing raceways and rollers are geometrically shaped.After the improved design, it has a higher bearing capacity. The new structure design of the flange and the roller end face not only improves the axial bearing capacity of the bearing, but also improves the lubrication condition of the contact area between the roller end face and the flange, and improves the service performance of the bearing.
