Cylindrical roller bearings — for high radial forces and high speeds

Cylindrical roller bearings have cylindrical rolling elements. They are designed for high radial loads and high speeds. For axial loads they are unsuitable. They have very good floating bearing properties.

Features of this series

Main dimensions according to DIN 5412-1. Suitable for high radial load-ratings and high speeds. Simplified mounting and dismounting by dismantling. Usually excellent non-locating bearing properties.

Versions of cylindrical roller bearings

NU: Two solid ribs on outer ring and an inner ring without ribs make possible an axial displacement in both directions.
NJ: Two solid ribs on the outer ring and one solid rib on the inner ring make possible a guidance in one axial direction.
NUP: Two solid ribs on the outer ring, one solid rib on the inner ring and one loose-rib washer make possible to be used as a locating bearing and an axial guidance in both directions.
N: Two solid ribs on the inner ring and an outer ring without ribs make possible an axial displacement in both directions.
NN: Three solid ribs on the inner ring and an outer ring without ribs make possible an axial displacement in both directions.

Material description

Cylindrical roller bearing made of rolling bearing steel: are economical, withstand extremely high load-ratings and are suitable for temperatures from circa -20°C up to +120°C. The rolling bearing steel is wear-resistant, shock-resistant, conductive and magnetic.
