Audited Supplier Roller Bearing Cylindrical Roller Bearing N1016 N1017 N1018 N1019 N1020 N1021 N1022 N1024
Cylindrical roller and the raceway was in line contact, radial load capacity. Both for heavy loads and shock loads, but also for high-speed rotation.
* Roller and raceway for line contact or repair offline contact, radial bearing capacity, suitable for heavy load and impact load.
* Friction coefficient is small, suitable for high-speed, speed close to the deep groove ball bearings.
* N-type and NU-type axial movement, can adapt to thermal expansion or installation error caused by the relative position of the shaft and shell changes, can be used for free-end support.
* Shaft or seat hole processing requirements are higher, the relative deviation of the outer ring axis after installation to strict control, so as not to cause contact stress concentration.
* Inner or outer ring can be separated, easy to install and remove.

Cylindrical Roller Bearing Models:
|
|
|
Single row cylindrical roller bearings:
|
N/NU, NUP, NJ/NF, NFP, NH(NJ+HJ)
|
|
Double row cylindrical roller bearings:
|
NN/NNU, NNF
|
|
Four row cylindrical roller bearings:
|
FC, FCD
|
|
N type:
|
The inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.
|
|
|
The outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.
|
|
NJ type:
|
The outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.
|
|
NF type:
|
The outer ring has one integral flange and the inner ring two integral flanges.
|
|
|
The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.
|
|
RN type:
|
No outer ring and the inner ring two integral flanges.
|
|
|
NN type bearing without ribs on outer ring,there is a wall in the midel of between both sides of inner ring. It can make shaft relative bearing between the axial displacement generated in both directions.
