SKF 29326 E 130x225x58 Spherical Roller Thrust Bearing

SKF 29326 E 130x225x58 Spherical Roller Thrust Bearing

SKF 29326 E is a spherical roller thrust bearing with dimensions 130x225x58 mm. Its design uses asymmetrical spherical rollers and a spherical raceway, allowing the bearing to accommodate very high axial loads acting in one direction, simultaneous radial load and angular misalignment between the shaft and housing. The E design identifies SKF's optimized internal geometry with larger rollers and increased load-carrying capacity.

SKF 29326 E Dimensions

The principal boundary dimensions of SKF 29326 E are:

Main dimensional identification:

130x225x58 mm

For this spherical roller thrust bearing, the third principal dimension of 58 mm is bearing height H. It should not automatically be described as width B, which is commonly used for many radial bearing designs.

SKF 29326 E Bearing Construction

SKF 29326 E is a spherical roller thrust bearing using asymmetrical spherical rollers running between specially shaped raceways.

The internal geometry provides a large effective roller-to-raceway contact area, which is fundamental to the bearing's ability to accommodate high axial loads.

The spherical raceway also gives the bearing self-aligning capability. This allows the bearing to accommodate a certain degree of angular misalignment between the shaft and housing and to tolerate shaft deflection within the limits specified for the bearing arrangement.

The roller-and-cage assembly together with the shaft washer forms a non-separable unit.

Cage Design

For SKF spherical roller thrust bearings in the E design within this size range, SKF uses a stamped steel window-type cage.

SKF 29326 E therefore uses:

Stamped steel window-type cage

The cage is an integral part of the bearing's optimized internal design and guides the spherical rollers during operation.

Loads and Operating Principle

SKF 29326 E is designed primarily to accommodate very high axial loads acting in one direction.

Its spherical roller geometry also enables the bearing to accommodate radial load. It can therefore operate under combined axial and radial loading when the complete bearing arrangement is correctly designed.

SKF catalogue load ratings for this bearing are:

C = 865 kN – basic dynamic load rating

C0 = 2500 kN – basic static load rating

Pu = 280 kN – fatigue load limit

C and C0 are standardized catalogue parameters used for bearing selection and service-life calculations. They should not be interpreted as simple maximum permissible operating loads for an installed bearing arrangement.

Actual permissible loading depends on the complete operating conditions and bearing arrangement.

Speed Ratings

SKF specifies:

Reference speed: 1,600 rpm

Limiting speed: 2,600 rpm

The actual permissible operating speed can depend on load, lubrication method, lubricant properties, operating temperature, heat dissipation and the design of the complete bearing arrangement.

The catalogue limiting speed should therefore not automatically be interpreted as the recommended continuous operating speed for every application.

Self-Aligning Capability

A key characteristic of SKF 29326 E is its self-aligning design.

The spherical raceway allows the bearing to accommodate angular misalignment between the shaft and housing as well as shaft deflection.

This feature is particularly important in bearing arrangements where perfect alignment cannot always be maintained under operating loads.

Self-alignment does not, however, remove the requirement for correctly manufactured bearing seats, proper mounting and appropriate alignment of the complete machine.

What Does SKF 29326 E Mean?

29326

29326 is the basic designation identifying this bearing within the SKF 293 dimensional series of spherical roller thrust bearings.

For this exact reference, the principal dimensions are:

130x225x58 mm

E

The suffix E identifies an optimized SKF internal design.

For SKF spherical roller thrust bearings, the E design uses larger rollers and optimized internal geometry to provide increased load-carrying capacity.

For SKF 29326 E, this design is combined with a stamped steel window-type cage.

The meaning of the SKF suffix E should not be transferred directly to bearings from other manufacturers, as suffix nomenclature is manufacturer-specific.

SKF 29326 E vs Conventional Thrust Bearings

SKF 29326 E should not be confused with a conventional thrust ball bearing.

Its spherical roller construction combines three important characteristics:

high axial load capacity, capability to accommodate radial load and self-aligning capability.

These construction differences are significant when selecting or replacing the bearing.

A bearing with the same 130 mm bore diameter – or even identical principal dimensions – is not automatically technically interchangeable with SKF 29326 E.

Selection and Interchangeability

When selecting a replacement, first identify the complete designation:

SKF 29326 E

and the principal dimensions:

130x225x58 mm

Matching dimensions alone do not establish full technical interchangeability.

When comparing SKF 29326 E with a bearing from FAG, NSK, NTN, TIMKEN, KOYO or another manufacturer, verify:

• bearing type and dimensional series
• d, D and H dimensions
• internal design
• dynamic and static load ratings
• fatigue load limit
• cage design and material
• permissible misalignment
• speed ratings
• dimensional and running tolerances
• lubrication requirements
• mounting dimensions
• manufacturer-specific suffixes

Another manufacturer's bearing carrying the basic designation 29326 may have the same principal dimensions, but its detailed construction and operating parameters must still be checked before substitution.

The suffix E is particularly important because manufacturer suffixes do not necessarily have equivalent meanings.

The precise catalogue identity is SKF 29326 E. Generic queries such as “29326 bearing”, “29326 thrust bearing” or “130x225x58 bearing” can help locate the product, but they are not sufficient on their own to confirm technical interchangeability.
