What Is a Spherical Roller Bearing?
A spherical roller bearing is a roller bearing designed primarily to handle high radial loads while accommodating a certain amount of shaft or housing misalignment.
It uses spherical or barrel-shaped rollers positioned between the inner and outer rings. The design allows the bearing to handle demanding loads while providing self-aligning capability.
Spherical roller bearings are commonly used in:
Heavy industrial machinery
Conveyor systems
Crushers
Gearboxes
Fans and blowers
Mining equipment
Steel machinery
Material-handling equipment
Because they are available in a wide range of dimensions, understanding the spherical roller bearing size chart is important when selecting a replacement or specifying a bearing for new machinery.
Understanding Spherical Roller Bearing Sizes
When looking at a spherical roller bearing size, three basic dimensions are particularly important:
Bore Diameter × Outside Diameter × Width
Bore Diameter
The bore diameter is the internal diameter of the bearing.
It determines the shaft size that the bearing is designed to fit.
Outside Diameter
The outside diameter is the diameter of the outer ring.
This dimension needs to match the available housing space.
Bearing Width
The width determines how much axial installation space the bearing occupies.
All three dimensions need to be considered when checking whether a bearing will physically fit into a machine.
However, dimensions alone don't tell you whether the bearing is suitable for the application.

Important: Treat this chart as a quick reference, not as a substitute for the manufacturer's dimensional catalogue. Bearing designations can have different configurations, clearances and suffixes, so confirm the exact specification before ordering.
How to Read a Spherical Roller Bearing Size Chart
A spherical roller bearing size chart usually contains several pieces of information.
The most important dimensions are:
d = Bore diameter
D = Outside diameter
B = Bearing width
For example, if a bearing is listed with:
d = 50 mm
D = 90 mm
B = 23 mm
the bearing has a 50 mm bore, 90 mm outside diameter and 23 mm width.
But the bearing number may contain additional information related to its construction and configuration.
Therefore, don't assume that two bearings with similar dimensions are automatically interchangeable.
Common Spherical Roller Bearing Series
Spherical roller bearings are manufactured in different series.
The series can influence:
Bearing dimensions
Load capacity
Roller size
Internal geometry
Speed capability
Overall weight
Some common designation families encountered in spherical roller bearings include:
222 series
223 series
230 series
231 series
232 series
239 series
240 series
241 series
The exact dimensions and performance characteristics differ between series.
This is why the complete bearing designation should always be checked before replacement.
Spherical Roller Bearing Bore Sizes
Bore diameter is one of the easiest ways to narrow down the required bearing.
Spherical roller bearings are available for a broad range of shaft diameters, from relatively small industrial shafts to very large heavy-duty applications.
Common bore sizes can include:
25 mm
30 mm
35 mm
40 mm
45 mm
50 mm
55 mm
60 mm
65 mm
70 mm
75 mm
80 mm
90 mm
100 mm
110 mm
120 mm
130 mm
140 mm
150 mm and above
The exact bearing series determines the corresponding outside diameter and width.
Cylindrical Bore vs Tapered Bore
When checking spherical roller bearing sizes, another important consideration is the bore configuration.
Cylindrical Bore
A cylindrical bore has a straight internal surface.
It can be installed using the appropriate shaft and fit arrangement.
Tapered Bore
A tapered bore has a conical internal surface.
These bearings may be mounted using:
Adapter sleeves
Withdrawal sleeves
Appropriate shaft arrangements
The mounting method depends on the bearing design and machine configuration.
Choosing between cylindrical and tapered bore construction isn't simply a dimensional decision. The shaft and mounting arrangement need to be considered.
What Is the Difference Between Bearing Size and Bearing Capacity?
A larger bearing isn't automatically the correct bearing.
Two spherical roller bearings can have similar bore sizes but different:
Load ratings
Internal clearances
Roller arrangements
Speed capabilities
Overall dimensions
Similarly, a physically larger bearing may not be appropriate if the machine doesn't have enough housing space.
Bearing selection should therefore consider both physical dimensions and operating requirements.
How to Choose the Correct Spherical Roller Bearing Size
Measure the Shaft
Start by measuring the shaft diameter accurately.
For an existing bearing, check the bearing designation before relying only on measurements.
Measure the Housing
Check the housing bore to determine the required outside diameter.
Measure Available Width
Make sure the bearing width fits within the available axial space.
Identify the Existing Bearing Number
If you're replacing an existing bearing, look for markings on:
Inner ring
Outer ring
Side face
Packaging
Previous purchase records
The complete number is extremely useful for identification.
Check the Load
Determine the expected radial and axial loads.
Check the Speed
Provide the operating RPM and any expected variations.
Check Internal Clearance
The appropriate clearance can depend on:
Shaft fit
Housing fit
Operating temperature
Load
Speed
Check the Bore Type
Determine whether the application requires a cylindrical or tapered bore.
Check the Operating Environment
Consider:
Dust
Water
Moisture
Chemicals
High temperature
Vibration
What to Actually Check Before You Buy
Before purchasing a spherical roller bearing, don't stop at the size chart.
Check these 10 important points:
Complete Bearing Number
The full designation provides much more information than the basic series.
Bore Diameter
Check the shaft size.
Outside Diameter
Confirm the housing dimensions.
Bearing Width
Make sure the bearing fits the available axial space.
Bearing Series
Different series can have different load and dimensional characteristics.
Internal Clearance
Check whether standard or special clearance is required.
Bore Configuration
Confirm cylindrical or tapered bore.
Load
Check radial, axial and shock loads.
Operating Speed
Verify that the bearing is appropriate for the required RPM.
Lubrication and Environment
Consider lubricant requirements, contamination and temperature.
Spherical Roller Bearing Size Chart vs Bearing Catalogue
A size chart is useful for quickly identifying dimensions.
However, a bearing catalogue usually provides much more information.
A detailed catalogue may include:
Bearing dimensions
Dynamic load rating
Static load rating
Limiting speed
Reference speed
Internal clearance
Mass
Bore options
Sealing options
Mounting information
Therefore, use a size chart to narrow down your options, but use the complete bearing specification when making the final selection.
Spherical Roller Bearing Dimensions Explained
Bore Diameter
The bore is identified as d in many bearing dimension tables.
It determines the shaft diameter.
Outside Diameter
Usually represented as D, it determines the housing size.
Width
Usually represented as B, it indicates the bearing's axial width.
Chamfer Dimensions
Some bearing specifications also provide chamfer dimensions.
These can be important when checking shaft shoulders and housing arrangements.
Why the Bearing Number Matters
Suppose you have an old bearing with a designation printed on the side.
That number can often help identify the:
Bearing series
Bore
Internal configuration
Clearance
Special features
This makes the bearing number one of the most useful pieces of information when purchasing a replacement.
If the marking is partially damaged, take a clear photograph and provide the visible characters to your bearing supplier.
Common Spherical Roller Bearing Applications
Conveyor Systems
Spherical roller bearings can be used in conveyor systems where shafts experience substantial radial loads.
Crushers
Crushers operate under heavy loads, vibration and shock.
The appropriate spherical roller bearing can provide the required load support in suitable designs.
Gearboxes
Industrial gearboxes can use spherical roller bearings for heavily loaded shaft arrangements.
Fans and Blowers
Large fans can experience shaft deflection and radial loading, making suitable self-aligning bearing arrangements useful.
Mining Equipment
Mining machinery operates in demanding environments involving dust, vibration and heavy loads.
Steel Machinery
Steel-processing machinery can involve high temperatures, heavy loads and continuous operation.
Spherical Roller Bearing Size Selection for Heavy-Duty Applications
For heavy-duty applications, size selection becomes even more important.
You need to consider:
Maximum load
Shock loading
Shaft deflection
Housing rigidity
Operating speed
Temperature
Lubrication
Misalignment
A bearing that physically fits may still be unsuitable if its load rating or operating capability doesn't meet the application's requirements.
Common Mistakes When Choosing Bearing Size
Choosing Only by Bore
A 50 mm shaft doesn't automatically mean every 50 mm bore spherical roller bearing is interchangeable.
Ignoring the Housing
The outside diameter needs to match the housing arrangement.
Ignoring Width
The bearing may fit the shaft and housing diameter but still be too wide.
Ignoring Clearance
Incorrect internal clearance can affect bearing performance and temperature.
Ignoring Speed
A bearing designed for heavy loads may not necessarily be the right choice for a high-speed application.
Ignoring the Application
Load, misalignment, lubrication and environmental conditions all influence selection.
Spherical Roller Bearing Maintenance
Correct bearing selection is only the first step.
Proper maintenance also helps improve service life.
Maintain Proper Lubrication
Use the appropriate grease or oil according to the bearing and application.
Prevent Contamination
Keep dust, water and metal particles away from the bearing.
Monitor Temperature
Unexpected temperature increases can indicate lubrication, load or installation problems.
Monitor Vibration
Changes in vibration can indicate bearing damage or machine problems.
Check Alignment
Spherical roller bearings can accommodate a degree of misalignment, but excessive misalignment should not be considered normal.
