Introduction to cylindrical roller bearings

The cylindrical roller is in linear contact with the raceway and has a large radial load capacity, which is suitable for bearing heavy loads and impact loads. It is also suitable

for high-speed rotation of N-type and NU type, which can move axially. It can adapt to changes in the relative position between the shaft and the shell caused by thermal

expansion or installation errors. It is suitable for use as a free end bearing. NJ type and NF type can withstand a certain degree of unidirectional axial load, while NH type 

and NUP type can withstand a certain degree of bidirectional axial load. The inner or outer rings can be separated, making it easy to install and remove NNU type and 

NN type, which have strong rigidity against radial loads and are mostly used for machine tool spindles

Main applicable retainers: steel plate stamped retainers (Z-shaped), copper alloy cut retainers, pin type retainers, synthetic resin formed retainers

Main uses: medium and large electric motors, generators, internal combustion engines, gas turbines, machine tool spindles, reduction devices, loading and unloading 

machinery, various industrial machinery

Solid needle roller bearings

The basic structure of bearings with inner rings is the same as that of NU cylindrical roller bearings, but due to the use of needle rollers, their volume can be reduced 

and they can withstand large radial loads. For bearings without inner rings, the installation surface of the shaft with appropriate accuracy and hardness should be used 

as the raceway surface

Main applicable cages: steel plate stamped cages，Main uses: automotive engines, transmissions, pumps, excavator track wheels, elevators, overhead cranes, compressors
