Details DrawingSpecifications Comments

The single-row cylindrical roller bearing is one separable type bearing. Generally, a single-row cylindrical roller ring consists of four major components as follows: inner ring, outer ring, rollers, and cage. The rollers are typically guided by two ribs of bearing ring . 


This kind of bearing is easy to assemble,disassemble and applicable for high-speed rotation cases. So, compared with a normal radial ball bearing with same size, the cylindrical roller bearing is more suitable to the condition which require to bear higher radial load and higher impact resistance. 


Normally,it is not used to bear an axial load. It is required the angle between the axes of its inner and outer rings is slight, generally less than 4'. Profiling of the rollers and the raceway generatrix can reduce the inclination requirement somewhat. 


We manufacture single row cylindrical roller bearings are available in several designs. The main difference is the configuration of the flanges. The most popular designs are N design,NU design,NJ design,NUP design.                               

Please kindly post your comments,we will attach great importance to it,and give our reply quickly.Thank you.
