Cylindrical Roller Bearings Introduction
Cylindrical roller bearings, generally separable bearings, are usually guided by two retaining edges of a bearing ring and consists of cage, roller and guiding ring. This bearing is convenient to be installed and dismantled, especially when the inner and outer ring as well as roller and shell have coordination.
This bearing is generally used to withstand radial loads, and only when the inner and outer ring are with the edge of the single row bearings, it can withstand smaller axial loads or larger intermittent axial loads. Compared with the deep groove ball bearings with the same external dimensions, it has larger radial load capacity, from the structural point of view, it also fits high speed rotation.
Cylindrical roller bearings are mainly used in machine tools, petroleum, vibrating screen, rolling mill handling machinery and various industrial machinery.
Cylindrical roller bearings are designed with cambered rollers and raceways so as to eliminate edge stress and improve bearing life.
Cylindrical roller bearings have a certain angle of inclination for the retaining edge, so its axial load is larger than the conventional design.
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.
