What Is a Spherical Roller Bearing?

A spherical roller bearing is a rolling-element bearing designed primarily to handle high radial loads while also accommodating certain axial loads and shaft or housing misalignment.

Unlike a standard ball bearing, spherical roller bearings use barrel-shaped or spherical rollers arranged between the inner and outer rings.

Their internal design allows the bearing to accommodate a certain degree of misalignment while maintaining rolling contact.

This makes spherical roller bearings particularly useful in demanding industrial applications where:

• Loads are high

• Shafts may deflect

• Housing alignment isn't perfect

• Shock loads occur

• Machinery operates continuously

How Does a Spherical Roller Bearing Work?

A spherical roller bearing generally consists of:

• Inner ring

• Outer ring

• Spherical rollers

• Cage

• Guide ring or internal guiding arrangement, depending on the design

The rollers are positioned between the inner and outer rings.

When the shaft rotates, the inner ring rotates with it while the rollers roll along the raceways.

The spherical geometry of the outer raceway allows the bearing to accommodate a degree of angular misalignment between the shaft and housing.

This self-aligning characteristic is one of the main reasons spherical roller bearings are used in heavy-duty machinery.

Why Are Spherical Roller Bearings Used?

Spherical roller bearings are particularly useful when an application requires a combination of:

• High radial load capacity

• Misalignment accommodation

• Shock-load resistance

• Continuous operation

• Reliable performance under demanding conditions

They are commonly considered for applications where ordinary deep groove ball bearings may not provide sufficient load capacity.

Main Features of Spherical Roller Bearings

High Radial Load Capacity

The roller design provides a relatively large contact area between the rolling elements and raceways.

This allows spherical roller bearings to handle high radial loads.

Self-Aligning Capability

The spherical outer raceway allows the bearing to accommodate a certain amount of misalignment.

This can be useful when:

• Shafts bend under load

• Housings aren't perfectly aligned

• Manufacturing tolerances cause alignment variation

Axial Load Capacity

Depending on the bearing design and operating conditions, spherical roller bearings can accommodate axial loads in addition to radial loads.

Suitable for Heavy-Duty Applications

Their robust construction makes them suitable for demanding machinery and industrial environments.

Resistance to Shock Loads

Spherical roller bearings can be used in applications where machinery experiences vibration and shock loading, provided the bearing is correctly selected.

Types of Spherical Roller Bearings

Spherical roller bearings are available in different designs depending on the application.

1. Open Spherical Roller Bearings

Open bearings are suitable where the bearing is installed in an environment with appropriate protection and where relubrication is required.

They are commonly used in industrial machinery.

2. Sealed Spherical Roller Bearings

Sealed spherical roller bearings provide additional protection against contaminants.

They can be considered where exposure to:

• Dust

• Moisture

• Water

• Other contaminants

is a concern.

3. Spherical Roller Thrust Bearings

Spherical roller thrust bearings are designed primarily for applications involving significant axial loads while also accommodating radial loads.

They are different from standard spherical roller bearings and should not be treated as direct substitutes.

Where Are Spherical Roller Bearings Used?

Spherical roller bearings are commonly found in heavy-duty industrial machinery.

Conveyors

Conveyor systems often operate continuously and can experience substantial radial loads.

Spherical roller bearings can be used in suitable conveyor pulley and shaft arrangements.

Crushers

Crushing equipment can expose bearings to:

• Heavy loads

• Shock

• Vibration

• Dust

Spherical roller bearings can be suitable for these demanding conditions when correctly selected and protected.

Gearboxes

Industrial gearboxes can generate significant radial and axial forces.

The appropriate spherical roller bearing can help support heavily loaded rotating shafts.

Fans and Blowers

Large industrial fans and blowers may require bearings capable of handling substantial radial loads and shaft deflection.

Mining Equipment

Mining machinery often operates under heavy loads and harsh environmental conditions.

Spherical roller bearings are commonly considered for applications such as:

• Crushers

• Conveyors

• Screens

• Material-handling equipment

Steel and Manufacturing Equipment

Industrial production equipment can involve high loads, vibration and continuous operation.

Spherical roller bearings can be used in various shaft-supporting arrangements.

Spherical Roller Bearing vs Ball Bearing

One common question is whether a spherical roller bearing is better than a ball bearing.

The answer depends on the application.

Feature	Spherical Roller Bearing	Ball Bearing
Rolling element	Spherical/barrel-shaped rollers	Balls
Radial load capacity	High	Moderate to high depending on type
Misalignment capability	High	Limited for standard designs
Shock-load suitability	Good	Application-dependent
Typical application	Heavy machinery	General machinery
Size	Generally larger	Often more compact

If the application involves high radial loads and misalignment, a spherical roller bearing may be more suitable.

For smaller loads and compact equipment, a deep groove ball bearing may be sufficient.

Spherical Roller Bearing vs Cylindrical Roller Bearing

Both are roller bearings, but their designs serve different purposes.

Feature	Spherical Roller Bearing	Cylindrical Roller Bearing
Roller shape	Spherical/barrel-shaped	Cylindrical
Misalignment	Accommodates a degree	Generally limited
Radial load capacity	High	High
Axial capability	Depends on design	Depends on design
Typical use	Heavy and misaligned applications	High radial load applications

The correct bearing depends on the shaft arrangement, load, alignment and operating conditions.

How to Choose the Right Spherical Roller Bearing

Choosing the correct spherical roller bearing requires more than matching the shaft diameter.

1. Determine the Bore

Start by identifying the shaft diameter.

The bearing's bore must match the shaft arrangement and required mounting fit.

2. Check the Outside Diameter

The bearing must fit properly within the housing.

3. Check the Bearing Width

Make sure there is sufficient axial space for the bearing.

4. Determine the Radial Load

Identify the load that the bearing needs to support.

Spherical roller bearings are generally selected for applications involving substantial radial loads.

5. Determine the Axial Load

If the bearing experiences axial forces, provide the direction and approximate magnitude if known.

6. Check Misalignment

Determine whether shaft deflection or housing misalignment is expected.

This is particularly important when deciding whether a spherical roller bearing is appropriate.

7. Check Operating Speed

Consider:

• Normal RPM

• Maximum RPM

• Acceleration

• Operating temperature

The bearing specification should be suitable for the required speed.

8. Consider Shock Loads

If the machine experiences sudden loading, vibration or impact, include this information when selecting the bearing.

9. Check Lubrication

Determine whether the bearing will use:

• Grease

• Oil

• Other suitable lubrication arrangements

10. Check the Environment

Consider exposure to:

• Dust

• Water

• Moisture

• Chemicals

• High temperatures

• Metal particles

Spherical Roller Bearing Sizes

Spherical roller bearings are available in a wide range of sizes.

The primary dimensions generally include:

Bore × Outside Diameter × Width

For example, if a bearing is specified with particular bore, outside diameter and width dimensions, all three need to match the machine's shaft and housing arrangement.

However, dimensions alone do not identify the complete bearing specification.

You should also check:

• Bearing series

• Internal clearance

• Cage design

• Sealing

• Load rating

• Speed capability

• Mounting arrangement

Understanding Spherical Roller Bearing Numbers

Spherical roller bearing designations can contain information about the bearing's:

• Series

• Bore

• Internal clearance

• Cage or construction

• Sealing

• Other configuration characteristics

This is why it is important to provide the complete bearing number, rather than only the first few digits.

If you're replacing an existing bearing, take a clear photograph of the markings before removing or discarding it.

What Is Internal Clearance?

Internal clearance refers to the amount of movement possible between the bearing's internal components before installation.

Clearance can affect:

• Operating temperature

• Load distribution

• Bearing performance

• Shaft and housing fits

The appropriate clearance depends on factors such as:

• Shaft fit

• Housing fit

• Operating temperature

• Speed

• Load

Therefore, don't automatically choose the most common clearance without checking the application.

Tapered Bore vs Cylindrical Bore

Spherical roller bearings can be available with different bore configurations.

Cylindrical Bore

A cylindrical bore has a straight internal diameter.

These bearings can be mounted directly onto suitable shafts using the required fit and mounting method.

Tapered Bore

A tapered bore has a conical internal surface.

Tapered-bore spherical roller bearings may be mounted using suitable adapters, sleeves or other arrangements depending on the design.

The correct mounting method should be selected based on the bearing and shaft arrangement.

What to Actually Check Before You Buy

Before purchasing a spherical roller bearing, check these points:

1. Complete Bearing Number

Take a clear photograph of the designation.
