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:

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

Normal suffix	Définition
E	Increased load capacity bearing
T	Fibreglass reinforced 66 polyamide cage
M	Solid brass cage (The M suffix is not indicated in all designation codes for cylindrical roller bearings)
W	Pressed metal cage
