Decoding SKF 23156 CCK/C3W33VA029
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 56Bore
- Bore 280 mm (56 × 5).
- CCK/C3W33VA029Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23156 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

When a shaft is not perfectly aligned with its housing, an SKF spherical roller bearing keeps the equipment running. Its two rows of rollers and spherical outer raceway let the inner ring tilt while the bearing still carries radial loads and axial loads in both directions. You will find this design in conveyors, mills, pumps and gearboxes, where alignment is rarely ideal. MR Industrial Accessories supplies SKF and helps you confirm the right bearing for the job.
Reading a designation such as 23156 CCK/C3W33VA029 is straightforward once you break it into blocks. The base number gives the dimension series. After it, CCK tells you the cage is stamped steel and the bore is tapered. The slash separates the C3 suffix, which means radial internal clearance is greater than normal. W33 indicates a lubrication groove with holes in the outer ring, and VA029 marks a specific execution variant. Ordering by the full code avoids surprises.
These bearings suit continuous processes where reliability matters: cement, mining, steel, paper, sugar and aggregate operations. They appear in gear reducers, ball and hammer mills, vibrating screens, industrial fans and washing machines. Because they compensate for misalignment, they work well on long shafts and on structures that flex. High-flow pumps and presses also use them.
Selection depends on the radial and axial load, the speed and the environment. Sealing is critical: use sealed or shielded variants where dust or moisture is present. Choose C3 clearance or greater for interference fits or when temperature differences exist. Lubrication must match the method, with high-viscosity grease or oil. During mounting, verify alignment and tighten fasteners properly; a tapered bore simplifies installation with an adapter sleeve.
Interchange between brands is possible because spherical roller bearings follow international dimensional standards, provided dimensions and functional suffixes align. Always confirm the complete code and tolerances. MR Industrial Accessories supplies SKF and can suggest alternatives when you are replacing an existing bearing. We work from the drawings or labels on your equipment.

Frequently asked questions
- SKF 23156 CCK/C3W33VA029 bearing: what are its dimensions?
- SKF 23156 CCK/C3W33VA029 measures 280 mm across the bore and 460 mm across the outside diameter; its width is 146 mm (280 x 460 x 146 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23156.
- What does the C3 suffix mean in a spherical roller bearing?
- C3 indicates internal radial clearance greater than normal. It is specified for interference fits or when temperature differences between inner and outer rings could reduce clearance during operation.
- How do I know if I need a bearing with a tapered bore?
- A tapered bore, marked with K in the designation, is used for mounting on an adapter sleeve or a tapered shaft. It simplifies installation and removal and allows radial clearance to be adjusted by moving the bearing axially.
- Can I replace an SKF bearing with another brand?
- Yes, if the main dimensions and functional suffixes match. International standards ensure dimensional interchangeability, but always check the full code and tolerances. MR Industrial Accessories can advise on the best option for your equipment.
