Decoding SKF 24172 ECCK30J/C3W33
- 241Series
- Spherical roller bearings, 241 series. Series differ in outside diameter and width even when the bore is the same.
- 72Bore
- Bore 360 mm (72 × 5).
- ECCK30J/C3W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24172 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

When shafts flex or mounting surfaces are not perfectly aligned, SKF spherical roller bearings keep equipment running. Their two rows of rollers run on a spherical raceway, so the inner ring can self-align as the shaft deflects. That makes them a practical choice for heavy machinery where high load capacity matters more than absolute rigidity.
The part number tells you what you are getting. Take 24172 ECCK30J/C3W33: the digits before the letters set the dimension series; EC marks an optimized, higher-capacity design; K means a tapered bore (1:12 or 1:30); J is the stamped steel cage; /C3 is internal radial clearance above normal; and W33 indicates a lubrication groove and holes in the outer ring. Reading each segment helps you confirm the bearing matches the mounting and lubrication setup.
These bearings show up in mining equipment, cement plants, steel mills, flour mills, conveyor belts, paper machines, large gearboxes, jaw crushers and vibrating screens. In all of them, loads are heavy and alignment is hard to hold. The self-aligning feature is what makes them work on long shafts or structures that flex under load.
Selection comes down to radial and axial load, speed, lubrication method and required internal clearance. Sealing options include open, shielded or sealed, depending on the environment. A tapered bore must fit correctly on a tapered shaft or adapter sleeve, and you should check alignment and lubrication before start-up. Wrong internal clearance can lead to overheating or early failure.
Cross-brand equivalences exist for standard series and suffixes, but codes are not always directly interchangeable. Cage design, heat treatment and tolerances can differ. For a replacement, compare the main dimensions and service conditions first. We can help you find the right option among the brands we supply.

Frequently asked questions
- SKF 24172 ECCK30J/C3W33 bearing: what are its dimensions?
- SKF 24172 ECCK30J/C3W33 measures 360 mm across the bore and 600 mm across the outside diameter; its width is 243 mm (360 x 600 x 243 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24172.
- What does the K suffix mean in a bearing designation?
- K indicates a tapered bore, usually 1:12 or 1:30. This allows mounting on a tapered shaft or with an adapter sleeve, which makes it easier to set the internal radial clearance.
- When should I use a bearing with C3 clearance?
- C3 clearance is greater than normal. It is used when there are temperature differences between shaft and housing, heavy interference fits, or high speeds. It helps avoid preload and overheating.
- How can I tell if a bearing from another brand is equivalent?
- Compare bore, outer diameter and width, plus bore type, cage and clearance. Even if suffixes match, materials or treatments may differ. Send us the part number and we will advise you.
