Decoding SKF 23156 CC/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).
- CC/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.

SKF spherical roller bearings handle radial loads together with axial loads in both directions, and they keep working when the shaft flexes or the supports are not perfectly aligned. The spherical outer raceway lets the bearing self-align inside the housing, which lowers the risk of damage from mounting that is not exact. Typical duty includes conveyors, mills, high-flow pumps and gearboxes. MR Industrial Accessories LLC supplies this line and helps you match the right variant to the application.
The part number tells you what you are getting. Take 23156 CC/C3W33VA029: the numeric prefix sets the dimension series, CC is the stamped steel cage with its roller guidance, C3 is internal radial clearance above standard, W33 means a lubrication groove and holes in the outer ring, and VA029 is a manufacturer-specific special suffix. Reading the code this way helps you order an exact replacement instead of a close one.
These bearings suit equipment where loads are heavy and shafts are not fully rigid: mining conveyors, cement mills, high-flow centrifugal pumps, speed reducers, paper machines and steelmaking equipment. They also appear in food processing, where cleanliness and corrosion resistance matter. Self-aligning behavior is the reason they are chosen when alignment between supports cannot be held.
Selection comes down to radial and axial load, speed and the environment. In dusty or wet areas, look at sealed or flinger variants. C3 or C4 clearance fits high temperatures or interference fits. Lubrication has to match the duty: high-viscosity grease for heavy loads, or circulating oil. At mounting, check alignment and avoid impacts that could mark the rollers. The CC cage is robust and takes moderate speeds.
Spherical roller bearings from other makers use similar designations, but suffixes are not always read the same way. W33 for the lubrication groove and holes is common, and C3 for radial clearance appears widely, yet interpretations differ. When replacing a bearing, compare dimensions and extra features rather than the series number alone. MR Industrial Accessories LLC can help you work out the correct interchange.

Frequently asked questions
- SKF 23156 CC/C3W33VA029 bearing: what are its dimensions?
- SKF 23156 CC/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 on an SKF bearing?
- C3 is an internal radial clearance larger than standard. It is specified when the bearing runs at high temperature or when the shaft and housing fits close up the clearance during mounting. Keeping the original designation avoids premature failure.
- When is a spherical roller bearing the right choice over a deep groove ball bearing?
- Use it for high radial loads, axial loads in both directions, or misalignment between shaft and support. It self-aligns and tolerates shaft flexing, which a deep groove ball bearing does not. It is also common in low-speed, high-load positions.
- How do I request a quote for an SKF bearing from MR?
- Send the full part number, for example 23156 CC/C3W33VA029, and the quantity by WhatsApp or email. If you do not have the number, send the measurements or a photo of the bearing instead.
