NU319 ECP Cylindrical Roller Bearing used in agricultural machine NU319ECP

Types 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.

Features

1.cylindrial roller bearing has a good radial load capacity, it's suitable for withstanding heavy load and shock load.

2. small friction coefficient, it's suitable for high-speed. And the limited speed is close to the deep groove ball bearing's.

3. N type and NU type can move axially, can adapt to errors due to thermal expansion or installation of the shaft and housing caused by changes in relative position, and can be used for supporting the free end.

4. High demanding for the processing of the axis and socket. After installing the bearing outer ring relative to the axis of deflection should be strictly controlled to avoid exposure to stress concentration

5. Inner and outer rings are detachable for easy installation and removal.

6.Cylindrical roller bearings are separable formed bearings. The rollers of cylindrical roller bearings have linear contact with the raceway, so the bearings can carry heavier radial load. They possess the characteristics of stability, anti-wearing property, high-speed, high-reliability.
