cylindrical roller locating bearing
Product description
Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling body and the ferrule is small, suitable for high-speed rotation. According to the presence or absence of ribs, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings. The bearing has a separable inner ring and outer ring structure.Generally use steel plate stamping cage, or copper alloy car body cage. But some also use polyamide forming cages
Product advantage
Feature and benefit
Type of cylindrical roller bearing
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.
