Single Row Cylindrical Roller Bearing

Single row cylindrical roller bearings with cages are part of radial roller bearings. Compared with the ball bearings’ balls, the rollers have a bigger contact to the roller axle. As a consequence, it can transfer higher forces, has higher stiffness, and in the same capacity load working condition, the diameter of the roller can be smaller. The rollers own profiled ends. For the basic design of all cylindrical roller bearings, the cylindrical rollers are guided within two ribs by at least one ring. This ring matches with the cage and rollers and become a fit unit. The other ring is removable and easier to mount and dismount.In general, the fit of the rings are tight one. Based on different arrangement of the ribs on the inner ring and outer ring, the bearings can be divided into NU, N, NJ, NF and NUP types. And the cage is usually pressed steel cage or machined brass cage.




Applications of Bearing

Type NU and N allow shaft moving, in an axial direction within limits, applicable to use as a free end. 

Type NJ and NF can bear a certain extent one-way axial loads. Type NUP can bear a certain extent two-way axial loads.


ZWA has supplied thousands of pieces of single row cylindrical roller bearings to the customers and those bearings favored the customer to reach the following goals:

  • Increase productivity 

  • Decrease the cost 

  • Higher operational security 

  • Longer maintenance intervals 

  • Longer bearing service life


Features of single row cylindrical roller bearings are as follows

  • Bear not only high radial loads but also axial loads from one or two directions. 

  • The separable design makes mounting, dismount, maintenance, and inspection easier and effective. 

  • Higher fatigue limit 

  • Lower heat generated from the bearings

  • Lower consumption on the lubrication 


Application fields of single row cylindrical roller bearings are as follows

Steel, gearbox, crane, automobile, vibration equipment, and reducers, etc.

Cleaning, Installation and Disassembly of Roller Bearings
A roller bearing is an assembly that supports the rotation of a shaft. Its ferrule and the roller are precision machined. Anti-rust oil or antirust grease is injected between the raceway and the rolli...
