Cylindrical Roller Bearing NJ/NU/NUP 2203ECP Size17x40x16mm

Products Description

DESCRIPTION

Cylindrical Roller Bearings are available in a wide range of designs, series, variants and sizes.

The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials.
The bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life.

FEATURES

* High load carrying capacity
* High stiffness
* Accommodate axial displacement

Except for bearings with flanges on both the inner and outer rings.
* Low friction the open flange design
* Together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capability.
* Long service life
The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
* Enhanced operational reliability
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
* Separable and interchangeable
The separable components of cylindrical roller bearings are interchangeable . This facilitates mounting and dismounting, as well as maintenance inspections.

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.
