Advantages of R&Z cylindrical roller bearing:
- Available in various designs
- High to very high load ratings
- Available with cylindrical or tapered bore
- Double row cylindrical roller bearings with cage can absorb very high radial forces due to the linear contact between rolling element and bearing ring. They are classified into two general designs which differ in flange position on the inner or outer ring. Double row cylindrical roller bearings can be disassembled and are easily installed or uninstalled. They are suitable for medium to high speeds, but they are rigid and cannot compensate angular misalignments.
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.
NU type:
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.
NUP type:
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:
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.
Application
