The most common designs of single row cylindrical roller bearings are shown here.


NU type bearing

Outer ring with two integral wing, inner ring without wing

Axial displacement of the shaft in two directions relative to the housing is allowed

To position the bearing upward on the shaft, use with the appropriate corner ring (the appropriate corner ring)


N type bearing

Inner ring with two integral wing, outer ring without wing

Axial displacement of the shaft in two directions relative to the housing is allowed


This type of bearings NJ

The outer ring with two integral side guard, the inner ring with one side guard

Axial displacement is allowed only in one direction relative to the housing

Used for axial positioning in one direction

To position the bearing upward on the other axis, use with the appropriate corner ring (the appropriate corner ring)


This type of bearings NUP

The outer ring belt has two integral gears, while the inner ring belt has one integral gears and one non-integral gears, that is, a movable gears

Used for axial positioning in two directions


The imperial bearing

The CRL and CRM series SKF inch bearing design (data sheet) conforms to the metric N series.These bearings are primarily used in the aftermarket, so SKF advises against using them in new bearing configuration designs.

Proper Angle ring (thrust ring)


Used with NU bearings for axial positioning in one direction

Angular rings should not be used on either side of the NU bearing to avoid axial extrusion of the roller.

Used with NJ type bearings for axial positioning in two directions

Made of carbon chromium bearing steel


Hardened and ground

With maximum axial runout, in accordance with the general tolerance class of bearings

It is represented by the serial model HJ plus the appropriate bearing size series and size


Separate order required

The reasons for designing the Angle ring as a bearing configuration include:

There are no NJ or NUP positioning bearings in the product range.

Provide a wider inner ring for the fixed-end heavy load bearing:

The NJ bearing with the HJ Angle ring has a longer inner ring width, while the NUP bearing has a narrower inner ring width with a movable wing

Simplify the design or installation process
