Single Row Cylindrical Roller Bearings

Single row cylindrical roller bearing consists of an inner and outer ring, rollers, and a cage; the outer and inner ring are separable; therefore, this type of bearings are easy to assemble, disassemble and applicable for high-speed rotation cases. Single row cylindrical roller bearing can carry a higher radial load capacity in comparison to same dimension ball bearing. Normally, it is not used to bear an axial load, in the case where there is a rib, the bearing can bear a slight axial load between the end of the rollers and the rib.

Depending on the existence of ribs on their rings, single row cylindrical roller bearings are classified into N, NU, NJ, NUP types.

Type N single row cylindrical roller bearing has two integral flanges on inner ring and a flangeless outer ring. This type of bearings permits axial displacement in double directions of the housing relative to the shaft.

Type NU single row cylindrical roller bearing has two integral flanges on outer ring and a flangeless inner ring. This type of bearings permits axial displacement in double directions of the housing relative to the shaft.

Type NJ single row cylindrical roller bearing has two integral flanges one on the outer ring, and one on the inner ring. This type of bearing can carry a certain amount of axial load in a single direction.

Type NUP single row cylindrical roller bearing has two integral flanges on outer ring, one flange and separable loose flange on inner ring. This type of bearing can carry a certain number of axial loads in double directions.
