Cylindrical roller bearings

Cylindrical roller bearings with cage

Cylindrical roller bearings are used in all types of electric motors where the radial load carrying capacity of a deep groove ball bearing would be insufficient, for example, in larger electric motors.
There are, however, only specific types of bearings that can support axial forces.

The different types are:

NU   Inner ring without rib, non-locating bearing, supports radial forces only
N   Outer ring without rib, non-locating bearing, supports radial forces only
NJ   Ribs on the outer ring, one rib on the inner ring, semi-locating bearing, supports axial forces in one direction
NUP   Supports axial forces in both directions, locating bearing
NJ + HJ   NJ bearing with additional L-section ring, supports axial forces in both directions


The product range of the Schaeffler Group comprises cylindrical roller bearings with an inside diameter from 15 mm (N202) to larger than 700 mm (NU19/710).

Cylindrical roller bearings are available unsealed only. They are lubricated on the end face. Cylindrical roller bearings generate more noise than deep groove ball bearings due to their kinematics. A cylindrical roller bearing must always be subjected to a radial load of at least 2 % of the dynamic load rating to prevent slippage and, thus, noise and damage.
