Cylindrical roller bearings have separable rings which facilitates mounting and removal. The two rings can if necessary be mounted tightened. Cylindrical roller bearings have a high radial load capacity due to the linear rollers in contact with the raceways and are suitable for high rotation speeds.

N and NU type rollers are free-end bearings.

NJ bearings are capable of taking some axial load in one direction.

NUP bearings are mounted as fixed bearings since they accommodate axial loads in both directions.

NJ bearings, associated with an HJ thrust collar are also used as fixed bearings.

Depending on the presence of thrust collars on the inner and outer rings, cylindrical roller bearings are classified as follows:

schéma NU schéma N schéma NJ schema NUP

 

Cages :

Cylindrical roller bearings have pressed steel or machined brass cages. ET type cylindrical roller bearings have fibreglass reinforced polyamide cages and can be used at constant temperatures of 125°C (150°C for short periods).

 

Series Polyamide cage Pressed metal cage Machined brass cage
NU10     1005 à 10/500
NU2 204 à 216 213 à 230 232 à 264
NU22 2204 à 2212 2213 à 2230 2232 à 2252
NU3 304 à 312 313 à 330 332 à 352
NU23   2304 à 2320 2322 à 2340

 

Acceptable misalignment:

Misalignment faults for cylindrical roller bearings vary since they depend on the type and internal specifications. Under normal loads, the angles are approximately as follows:

Cylindrical roller bearings, series 0 or 1 width: 4 minutes

Cylindrical roller bearings, series 2 width: 2 minutes

M  Solid brass cage (The M suffix is not indicated in all designation codes for cylindrical roller bearings)
W  Pressed metal cage
