The use of cylindrical roller bearings

Cylindrical roller and raceway line contact bearings, radial load capacity, that is suitable to withstand heavy loads and shock loads, but also for high-speed rotation can be N-type and NU type axial movement, able to adapt or installation error due to thermal expansion caused the relative position of the shaft and the shell changes, the most adapted for the free end bearing NJ-type and NF type can withstand a certain degree of unidirectional axial load, NH-type and NUP type can withstand a certain degree of bi-directional axial load inner or outer detachable ring for easy assembly and disassembly NNU and NN-based anti-type radial load rigidity.

     Most of the major application for the machine tool spindle retainer: steel stamping cage (Z shape), copper alloy cutting system cage, pin type cage, synthetic resin forming the cage.

     Main use: medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, and material handling machinery, various types of industrial machinery.

     Entity type needle roller bearings: a basic structure of the inner bearing NU type cylindrical roller bearings the same, but with needle, size can be reduced, and can withstand large radial load bearing without inner ring should have the right precision and hardness the axis of the mounting surface to use as a raceway.

     Main application of the cage: steel stamping cage

     Main use: car engines, transmissions, pumps, crawler excavators wheel, hoist, crane, compressor.
