SKF 29322 E 110x190x48 mm

Technical Specification

The dimensions 110x190x48 mm refer respectively to the bore diameter, outside diameter and overall bearing height.

Bearing Construction and Operating Principle

The SKF 29322 E belongs to the SKF spherical roller thrust bearing family, which is specifically designed for applications involving substantial axial loading.

Unlike conventional thrust ball bearings, spherical roller thrust bearings use barrel-shaped rolling elements operating between specially profiled raceways.

The principal components include:

• Shaft washer with a precision-engineered raceway.

• Housing washer with a spherical raceway.

• Spherical rolling elements transmitting loads between the raceways.

• Pressed steel cage maintaining correct roller spacing and guidance.

The spherical geometry enables the bearing to accommodate angular misalignment while maintaining load distribution across the rolling elements.

The roller-to-raceway contact geometry provides high load-carrying capability, particularly under heavy axial loading.

SKF 29322 E Designation Explained

What does the E suffix mean?

The E suffix identifies an SKF internal design used in spherical roller thrust bearings.

For SKF 29322 E, this design incorporates a pressed steel window-type cage and an optimized internal arrangement intended to provide high load-carrying capacity.

The cage forms part of the non-separable shaft washer and roller assembly.

The E suffix does not indicate a bearing clearance class, precision tolerance class or sealing configuration.

It is important to preserve the complete designation SKF 29322 E when identifying the bearing for procurement or technical replacement.

Axial and Radial Load-Carrying Capability

SKF 29322 E is primarily designed to accommodate heavy axial loads acting in one direction.

Its internal geometry also enables it to support radial loads acting simultaneously with a suitable axial load.

However, spherical roller thrust bearings require an adequate axial load to maintain correct rolling conditions.

The bearing is not intended to operate under radial loading alone.

Basic load ratings

The basic dynamic load rating is used in bearing rating-life calculations under defined conditions.

The basic static load rating relates to the bearing's resistance to permanent deformation under static loading.

Neither value represents a universally permissible continuous operating load.

Actual operating limits depend on load direction, speed, lubrication, temperature and bearing arrangement.

Self-Alignment and Misalignment Compensation

One of the main engineering advantages of SKF spherical roller thrust bearings is their ability to accommodate angular misalignment between the shaft and housing.

The spherical housing washer raceway allows the roller assembly to adjust its angular position within the permitted operating limits.

This capability can help reduce the effects of shaft deflection, mounting inaccuracies and structural deformation.

However, permissible misalignment is not unlimited.

The allowable angle depends on operating load, bearing arrangement and the manufacturer's recommendations.

Correct shaft and housing alignment remains important for reliable bearing performance.

Cage Design and Roller Guidance

SKF 29322 E incorporates a pressed steel window-type cage.

The cage maintains the circumferential spacing of the spherical rollers and contributes to their guidance during operation.

The shaft washer, rollers and cage form a non-separable assembly, while the housing washer can be handled separately.

The cage design must be considered when evaluating bearing compatibility and replacement requirements.

The E designation should not be interpreted as specifying a machined brass cage.

Rotational Speed and Operating Limits

The rotational speed capability of SKF 29322 E depends on lubrication conditions, operating load, heat generation and bearing arrangement.

SKF catalogue values are:

The reference speed is a thermal reference value established under defined conditions.

The limiting speed represents a mechanical speed boundary associated with bearing design and operating considerations.

These values do not guarantee that either speed can be achieved in every installation.

The permissible operating speed must be determined from the actual application conditions.

Lubrication Requirements

Proper lubrication is essential for spherical roller thrust bearings because of the combined rolling and sliding movements occurring within the bearing.

Lubricant selection should consider:

• Operating speed.

• Axial and radial loads.

• Operating temperature.

• Required lubricant viscosity.

• Lubrication method and oil supply.

• Heat dissipation.

• Housing construction and contamination control.

Oil lubrication is commonly used for spherical roller thrust bearings, particularly in heavily loaded or higher-speed industrial applications.

The selected lubricant must provide an adequate lubricating film under the intended operating conditions.

Lubrication intervals, oil flow requirements and viscosity should be established using SKF technical guidance and the machine manufacturer's requirements.

Minimum Axial Load Requirement

Spherical roller thrust bearings require a minimum axial load to maintain correct rolling conditions and reduce the risk of roller sliding.

For SKF 29322 E, the SKF minimum load factor A is 0.28.

This factor is used in the manufacturer's calculation method for determining the required minimum axial load.

The minimum load must not be estimated solely from the basic dynamic or static load rating.

Insufficient axial loading can adversely affect rolling behaviour, friction and bearing service life.

The required minimum axial load should be calculated for the actual speed, lubrication conditions and bearing arrangement.

Industrial Applications

SKF spherical roller thrust bearings of the 293 series may be considered for industrial bearing arrangements involving heavy axial loading.

Potential application areas include:

• Heavy industrial machinery.

• Mechanical transmission systems.

• Industrial gear units.

• Vertical shaft arrangements.

• Process equipment with significant axial forces.

• Selected industrial drive assemblies.

These are potential applications of the bearing family rather than a manufacturer-confirmed application list for the exact SKF 29322 E.

Final bearing selection must be based on load calculations, operating conditions and the mechanical design of the equipment.

Bearing Selection and Installation

Correct selection of SKF 29322 E requires verification of the complete bearing designation, dimensional compatibility and operating requirements.

Important engineering considerations include:

Shaft and Housing Fits

The shaft and housing seating surfaces must provide the required dimensional accuracy, surface finish and support.

Fits should be selected according to the operating load and mounting arrangement.

Load Direction

SKF 29322 E accommodates axial loads in one direction.

Applications involving axial loads in both directions require an appropriately designed bearing arrangement.

Axial and Radial Load Combination

Simultaneous radial loading must be evaluated in relation to the axial load and SKF application limits.

Lubrication and Temperature

Lubricant viscosity, heat generation and operating temperature influence bearing performance and service life.

Mounting Procedure

Mounting forces must be applied using methods appropriate to the bearing construction.

Forces must not be transmitted through the rolling elements in a manner that could damage the raceways.

Bearing Interchangeability

Matching dimensions alone do not establish full interchangeability with another manufacturer's bearing.

Load ratings, internal design, cage configuration, speed limits and installation requirements must also be checked.
