How to read SKF 24140 CCK30/C3W33
- 241Series
- Spherical roller bearings, 241 series. For the same bore, each series has a different outside diameter and width.
- 40Bore
- 200 mm bore: 40 × 5.
- CCK30/C3W33Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
24140 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF spherical roller bearings of the 240 series with CCK and CW suffixes are two-row roller components, with tapered bore and a design optimized to withstand combined loads and angular misalignment. They are used in applications where the shaft may flex or where mounting is not perfectly aligned, such as industrial drives, mining equipment and heavy machinery. MR Accesorios Industriales carries this line as part of its SKF bearing offering.
The designation of these bearings is interpreted as follows: the basic number, for example 24026, indicates the size and the dimension series. The CCK suffix indicates a stamped steel cage design, roller-guided, and tapered bore (K). The C3 or C4 suffixes indicate the internal radial clearance, which in this case is greater than normal. W33 means that the bearing incorporates a groove and three lubrication holes in the outer ring. Thus, a code such as 24028 CCK30/C3W33 combines a 1:30 tapered bore, steel cage, C3 clearance and lubrication through the outer ring.
These bearings are used in equipment where loads are high and misalignment may occur, such as conveyor belts, mills, crushers, industrial fans and machines for the cement, mining and steel industries. In Argentina, they are common in mineral processing plants, in the oilseed industry and in earthmoving equipment. Their ability to withstand radial and axial loads in both directions makes them suitable for long shafts subjected to bending.
To select correctly, take into account the load, the speed and the environmental conditions. The tapered bore requires a suitable adapter sleeve (H, AH or HE) to secure it to the shaft. C3 or C4 internal clearance is useful when there are interference fits or thermal gradients. Lubrication must be chosen according to temperature and speed; the W33 groove and holes make relubrication easier. Initial alignment is less critical than in other bearings, but it is advisable to verify that misalignment does not exceed the permissible limits.
As for equivalents, spherical roller bearings from other brands with similar designations can be interchanged, but always verify dimensions, clearance and suffixes. Not all manufacturers use the same nomenclature for the tapered bore or the lubrication grooves. It is advisable to compare the technical specifications before replacing one bearing with another of a different brand. At MR Accesorios Industriales we can advise you on interchangeability and source the exact part number you need.
If you already have the part number of your SKF bearing, send it by WhatsApp to MR Accesorios Industriales and we'll quote you. We can also help you identify the right replacement if you don't have the complete designation. Our technical team is here to advise you on the selection, mounting and lubrication of spherical roller bearings for your industrial application.

Frequently Asked Questions
- What are the dimensions of the SKF 24140 CCK30/C3W33 bearing?
- The SKF 24140 CCK30/C3W33 bearing has a 200 mm bore, a 340 mm outside diameter and a 140 mm width (200 x 340 x 140 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 24140.
- What does the CCK suffix mean in an SKF bearing?
- CCK indicates a design with 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 the size. This allows mounting it 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. A greater clearance compensates for the reduction in internal clearance due to expansion and prevents overloads. Always verify the 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, extending its service life in applications with high load or contaminated environments.
