Cylindrical rollers have linear contact with the raceway , and the bearings can carry
heavier radial load . Applicatiins are foundin situations characterized by heavy load and
alsohigh rotation speed.
The N type and NU type bearings can be movable along theshaft . They can adapt
to the position changes between the shaft and housing caused by the thermal expansi
on or the mountingerror and are most suitable for free end shafts.
NJ and NFtypes can accept certain axial load in one dirction , and NH and NUP types
can accept certain axial load in two directions.
Inner ring and outer ring can be separable , and they are convenient to mount and dis
mount.
The rigidity in carrying tadial lioad in the NNU and NN types makes them applicale for
machine tool spindles.
FC,FCD and FCDP types can carry comparatively heavy radial load and are mainly ap
plied for mill rolls.
Applications of these bearings are mostly found in middle-sized and large-sized moto
rs,electricity generators, intenal combustion engines, gas turbines,machine tool tool spin
dles, deceleration devices,unloading and lifting machines and other industrial machines.
