Cylindrical roller bearing is one type of the bearing which cylinders are used as the rolling elements. Cylindrical roller bearings have high load capacity. They mainly bear with radial load and are suitable for high speeds. The inner ring and outer ring of this kind of bearing could be seperated.
The roller and raceway for line contact or take off contact
The cylindrical roller bearing have low friction coefficient, suitable for high speed, the limit speed is close to deep groove ball bearings
The inner ring and outer ring could be separated, and it is easy for installation and remove.
According to whether the ring have the ribs. The cylindrical roller bearing could divided into NU, NJ,NUP,N,NF etc.
N, NU Series
N and NU series are single row cylindrical roller bearing, and N series have two fixed ribs in the inner ring, and NU type cylindrical roller bearing have two fixed ribs at outer ring, and one smooth inner ring. These two type of bearing are mainly used in non-locating bearing units
NJ, NF Series
NJ series have two fixed ribs on the outer ring, and one rib on the inner ring, This type of bearing can mainly endure a certain amount of unidirectional axial load., NF series have one rib on outer ring and two integral ribs on the inner ring, and could endure a certain amount of unidirectional axial load as well. Therefore the N and NF series could suitable for guide the shaft in a single direction(axially)
