RNU series cylindrical roller bearings,
(
RNU2 / RNU3 )
NU bearing without an INNER ring,
CHROME STEEL AISI52100, METRIC sizes

 


CLI 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.
These bearings' 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. Those bearings 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.‚Äč

Below is the list of pupular bearing types we are producing and supplying to our customers: 

 * NU - Two solid ribs on outer ring and one 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 the axial direction.
 * NF - Two ribs on the inner ring and one rib on the outer ring.
 * NUP - Two solid ribs on the outer ring, a solid rib on the inner ring and a loose rib washer make possible the use as a locating bearing and an axial guidance in both directions.
 * N - Two solid ribs on the inner ring and one outer ring without ribs make possible an axial displacement in both directions.
 * RNU - NU series cylindrical roller bearings without an inner ring. 
 * RN
- N series cylindrical roller bearings without an outer ring.
