Product Description

1. What is a Cylindrical Roller Bearing?
 
Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.
 
The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.
 
2. More information:
 
With the absence of ribs, either the inner or outer ring will move freely so as to adjust to axial movement hence can be used as free side bearings. This enables them to absorb shaft expansion to a certain extent, relative to the housing position.
 
NU and NJ type cylindrical roller bearing produce high performance results when used as free side bearings because they possess the required characteristics for that purpose. NF type cylindrical roller bearing also supports the displacement of the axial to a certain extent in both directions and therefore can be used as a free side bearing.
 
In applications where heavy axial loads have to be supported, cylindrical roller thrust bearings are the most suitable. This is because they are designed to contain shock loads, are stiff and the axial space required is little. They only support axial loads that are acting in a single direction.
