Decoding SKF 23044 CCK/C3W33
- 230Series
- Spherical roller bearings, 230 series. Series differ in outside diameter and width even when the bore is the same.
- 44Bore
- Bore 220 mm (44 × 5).
- CCK/C3W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23044 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 23044 CCK/C3W33 measures 220 mm across the bore and 340 mm across the outside diameter; its width is 90 mm (220 x 340 x 90 mm).

When a shaft and housing are not perfectly in line, the bearing has to absorb that misalignment while still carrying heavy radial load and a share of axial load. The SKF 222 series with CCK, C3 or C4 and W33 suffixes is built for exactly that duty: two rows of rollers, a self-aligning outer ring, a 1:12 tapered bore and a stamped steel cage.
Reading a code such as 22228 CCK/C3W33: the 222 block identifies the medium-width spherical roller bearing series, 28 is the size code, CCK covers the internal design with tapered bore and stamped steel cage, C3 or C4 sets radial internal clearance above normal, and W33 means the outer ring carries a lubrication groove plus holes. The series covers a range of sizes, offered in C3 or C4 combined with W33.
Typical service is in mining, cement, steel, paper, aggregate processing and heavy transport. Conveyors, mills, crushers, screens, industrial fans and paper machines are common homes for this line, particularly where long shafts or welded frames make perfect alignment unrealistic and the bearing must keep its load capacity anyway.
Selection comes down to radial and axial load, speed, fit and internal clearance. A CCK tapered bore sits on a tapered shaft or an adapter sleeve; the C3 or C4 clearance is matched to working temperature and fit. Whatever the choice, grease or oil has to reach the W33 groove and holes, and correct initial alignment plus adequate sealing keeps contamination out.
Other brands offer tapered-bore spherical roller bearings with similar suffixes, yet internal codes and clearance classes do not always line up. Never swap by number alone: check dimensions, clearance and cage style, and compare tolerances and load ratings rather than just bore and width.

Frequently asked questions
- SKF 23044 CCK/C3W33 bearing: what are its dimensions?
- SKF 23044 CCK/C3W33 measures 220 mm across the bore and 340 mm across the outside diameter; its width is 90 mm (220 x 340 x 90 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23044.
- What does CCK tell me about the bearing?
- It describes the internal design: a 1:12 tapered bore with a stamped steel cage. The taper lets the bearing mount on a tapered shaft or adapter sleeve, which simplifies setting radial clearance and later removal.
- When should I pick C3 or C4 instead of normal clearance?
- These clearance classes suit elevated operating temperatures, tight fits or misalignment that builds internal stress. The extra clearance gives room for expansion so the bearing does not end up preloaded.
- Why does the W33 suffix matter for maintenance?
- W33 means the outer ring has a lubrication groove and holes, so relubrication can be done through the housing. That helps on equipment that is hard to reach or runs on long service intervals.
