Cylindrical Roller Bearings

Cylindrical roller bearings ( also called CRB in short) are a kind of radial rolling bearings with cylindrical rollers. The rollers are lined in parallel shapes, in between the rollers are cages that are able to avoid the leaning of roller or friction between rollers. In consequence, the rotating torque is also avoided. The contact between the cylindrical rollers and the raceways is linear contact. In general, cylindrical roller bearings adopt pressed steel cages or machined brass cages.


Cylindrical roller bearings can be classified in several types based on different index.

Based on the row of rollers, cylindrical roller bearings can be divided into single row cylindrical roller bearing, double row cylindrical roller bearing and double row cylindrical roller bearing.

Based on the ribs of the rings, cylindrical roller bearings can be divided into NU, NJ, NUP, N, NF, NNU, NN etc types. For this classification, the inner ring and outer ring is separable. ZWA Bearings manufactures types of cylindrical roller bearings to meet customers' demand in diferent industries like mining, steel making, etc..

Cylindrical Roller Bearings Advantages & Benefits

They can bear heavy radial loads because while the loads grow heavier, cylindrical roller bearings’ rollers can be kept static. Meanwhile, they can also bear some slight thrust loads. 


They are able to reduce friction due to their cylinder shapes. Meanwhile, these bearings also have a crowned surface which prevents the stress from concentrating on one special point. 


The inner ring and outer ring of ZWA’s cylindrical roller bearings are interchangeable. Meanwhile, the separable feature of inner and outer rings make the mounting, dismounting, maintenance, and inspection are more convenient and effective. 


Last but not least, cylindrical roller bearings are also capable of bearing axial displacement in the equipment, especially in that application with vibration, cylindrical roller bearings stand out among other roller bearings.


Cylindrical roller bearings are mainly applied in the following fields:

Rolling mills, vibration equipment, reducers, motors, etc.
