Decoding SKF 24156 CCK30/C2W33
- 241Series
- Spherical roller bearings, 241 series. Series differ in outside diameter and width even when the bore is the same.
- 56Bore
- Bore 280 mm (56 × 5).
- CCK30/C2W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24156 is the standard ISO basic designation, which sets the bearing type, series and bore.

SKF 240 CCK/CW spherical roller bearings are two-row units with a tapered bore, built to handle combined radial and axial loads plus angular misalignment. They suit industrial drives, mining equipment and heavy machinery where shaft flex or imperfect mounting alignment is a concern. MR Industrial Accessories LLC supplies this line as part of its SKF bearing range.
Reading the part number helps you confirm the right variant. The base number, such as 24026, sets the size and dimension series. CCK tells you the cage is stamped steel and roller-guided, and the K confirms a tapered bore. C3 or C4 indicates internal radial clearance above normal. W33 means the outer ring has a lubrication groove and three holes. So 24028 CCK30/C3W33 combines a 1:30 taper, steel cage, C3 clearance and outer-ring lubrication.
These bearings fit equipment where loads are heavy and misalignment can occur: conveyor belts, mills, crushers, industrial fans, and machines in cement, mining and steel production. Their ability to take radial and axial loads in both directions makes them suitable for long shafts that bend under load.
For selection, consider load, speed and the operating environment. A tapered bore needs an adapter sleeve (H, AH or HE) to mount on the shaft. Choose C3 or C4 clearance when interference fits or thermal gradients are present. Lubrication depends on temperature and speed; the W33 groove and holes simplify relubrication. Initial alignment is less critical than with other bearing types, but verify that misalignment stays within permissible limits.
Interchange is possible with spherical roller bearings from other brands that use similar designations, but always check dimensions, clearance and suffixes. Nomenclature for tapered bores and lubrication grooves varies between manufacturers. Compare technical specifications before substituting one brand for another. MR Industrial Accessories LLC can advise on interchangeability and source the exact part number you need.

Frequently asked questions
- SKF 24156 CCK30/C2W33 bearing: what are its dimensions?
- SKF 24156 CCK30/C2W33 measures 280 mm across the bore and 460 mm across the outside diameter; its width is 180 mm (280 x 460 x 180 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24156.
- What does the CCK suffix mean in an SKF bearing?
- CCK indicates a stamped steel cage guided by the rollers and a tapered bore. The final K confirms the tapered bore, which may be 1:12 or 1:30 depending on size. This allows mounting with an adapter sleeve on cylindrical shafts.
- When is a C3 or C4 radial clearance advisable?
- C3 or C4 clearance is chosen when there are interference fits, thermal gradients between rings or high speeds. Greater clearance compensates for reduced internal clearance due to expansion and helps prevent overloads. Always verify operating conditions.
- What advantage does the W33 groove and holes provide?
- The W33 designation indicates that the outer ring has a groove and three holes for lubrication. This makes direct relubrication to the rollers easier without dismounting the bearing, which helps in applications with high load or contaminated environments.
