Decoding SKF 24028/C3W33VA9B1
- 240Series
- Spherical roller bearings, 240 series. Series differ in outside diameter and width even when the bore is the same.
- 28Bore
- Bore 140 mm (28 × 5).
- C3W33VA9B1Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24028 is the standard ISO basic designation, which sets the bearing type, series and bore.

For equipment where shaft deflection or mounting misalignment is a fact of life, SKF spherical roller bearings provide a self-aligning solution. With two rows of rollers, they handle heavy radial loads and axial loads in both directions. MR Industrial Accessories supplies this SKF line and helps you decode the complete designation so you get the right execution for your application.
The designation 24028/C3W33VA9B1 packs a lot of information. The basic number 24028 tells you it is a spherical roller bearing: the 24 prefix indicates series 40, and the last two digits give the size. The suffixes define the execution: C3 is internal radial clearance greater than normal, W33 means the outer ring has a groove and three lubrication holes, and VA9B1 identifies a special sealing and tolerance variant. So this bearing combines C3 clearance, a lubrication groove, and special sealing in one unit.
These bearings are at home on long shafts or shafts that bend, where perfect alignment is not realistic. You will find them in conveyors, mills, crushers, large centrifugal pumps, industrial fans, paper machines, and mining equipment. Their self-aligning ability lowers the risk of early failure when the shaft or housing is slightly off.
When selecting a replacement, look at radial and axial load, speed, and the environment. The W33 groove and holes make relubrication easier in dirty or damp conditions. The VA9B1 execution typically includes seals that hold grease in and keep contaminants out. At mounting, check initial alignment, radial clearance, and lubricant type. Using a press or controlled heating helps avoid ring damage and supports bearing life.
Spherical roller bearings are identified by their basic designation and standardized suffixes. Different brands may list the same designation, but special executions such as sealed versions or clearance variants can differ. When sourcing a replacement, compare sealing, clearance, and tolerances as well as the number. If you are unsure, send us the complete code and we will help you find the right option.

Frequently asked questions
- SKF 24028/C3W33VA9B1 bearing: what are its dimensions?
- SKF 24028/C3W33VA9B1 measures 140 mm across the bore and 210 mm across the outside diameter; its width is 69 mm (140 x 210 x 69 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24028.
- What does the C3 suffix mean in an SKF bearing?
- C3 indicates internal radial clearance greater than normal. It is specified when the bearing runs at higher temperatures or with interference fits that reduce clearance during operation. Always follow the original equipment specification.
- What is the purpose of the W33 lubrication groove and holes?
- W33 means the outer ring has a groove and three holes for relubrication. This is useful when access is limited or the environment is contaminated, as it simplifies periodic maintenance.
- How do I know if a bearing from another brand is equivalent to the SKF I need?
- Compare the basic designation and suffixes. If the type, clearance, and sealing match, it is likely interchangeable. If in doubt, consult us with the complete code to verify compatibility and avoid failures.
