NN3018/ P2 high precision cylindrical roller bearing

NN3018 double row cylindrical roller bearing,P2 class, high precision bearings

The rollers of NN design cylindrical roller bearings are guided between integral flanges on the inner ring, while the rollers of NNU design bearings are guided between integral flanges on the outer ring. In either case, the other ring has no flanges. Therefore, the bearing can accommodate axial displacement of the shaft relative to the housing in both directions, within the bearing.

These bearings are separable, i. e. The bearing ring with integral flanges, together with the roller and cage assembly can be separated from the flangeless ring, to facilitate mounting and dismounting.

Double row cylindrical roller bearings NN type has three flanges on outer ring and no flange on inner ring. Double row cylindrical roller bearings NNU type has no flange on outer ring and three flanges on inner ring.

The cages of double row cylindrical roller bearings are made through machine steel or brass.
