Cylindrical roller bearings High speed low noise N NU NJ NUP
Product Description
The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial loads. The friction between the rolling element and the collar edge is small, suitable for high-speed rotation. According to the presence or absence of ribs on the ring, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a separable structure with inner and outer rings.
Cylindrical roller bearings without retaining edges on the inner or outer rings can move relative to the axial direction, so they can be used as free end bearings. A cylindrical roller bearing with double ribs on one side of the inner and outer rings, and a single rib on the other side of the ring, which can withstand a certain degree of axial load in one direction. Generally, steel plate stamped cages or copper alloy solid cages are used. But some also use polyamide shaped cages.

Specifition
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.
