Cylindrical roller line contact with the raceway bearings, radial load capacity, that is suitable to withstand heavy load and shock load, but also for high-speed rotation of N type and NU type can move axially, can adapt due to thermal expansion or installation errors caused changes in the relative position of the shaft and housing, the most adapted as a free end of the axial load miniature ball bearings NJ-type and NF type can withstand a certain degree, NH type and NUP type can withstand a certain degree of axial load inner or outer Circle detachable, easy assembly and disassembly NNU and NN-type anti-radial load rigidity.

Cage most suitable for the main spindle: steel stamping cage (Z-shaped), cutting copper alloy cage, pin-type cage, synthetic resin forming cage.
Main purpose: medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, handling machinery, industrial machinery.
Entity type needle roller bearings: inner ring of the bearing and the basic structure of NU type cylindrical roller bearings the same, but because of the use of the needle, the volume can be reduced, and can withstand high radial load bearing without inner ring should have a suitable precision and hardness The mounting surface of the shaft as a raceway use.
Mainly used to maintain frame: steel stamping cage main purposes: car engines, transmissions, pumps, crawler excavators wheel, hoist, crane, compressor.
