Decoding SKF 23088 CAK/C3W33
- 230Series
- Spherical roller bearings, 230 series. Series differ in outside diameter and width even when the bore is the same.
- 88Bore
- Bore 440 mm (88 × 5).
- CAK/C3W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23088 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 23088 CAK/C3W33 measures 440 mm across the bore and 650 mm across the outside diameter; its width is 157 mm (440 x 650 x 157 mm).

SKF spherical roller bearings in the CAK/C…W… series handle heavy radial loads and axial loads in both directions. Because they are self-aligning, they tolerate angular misalignment between shaft and housing, which helps where shafts deflect or mounting is less than perfect. You will find them in mining and cement equipment, steelmaking, heavy machinery and power transmission drives.
Reading the code helps you confirm what you are ordering. CAK means a tapered bore with a 1:12 taper plus a groove for a locking ring, so the bearing mounts on a tapered shaft or with an adapter sleeve. The letter C followed by a number sets the internal radial clearance, and that clearance grows as the number goes up. W means the outer ring has a lubrication groove and holes. The final 33 identifies a stamped steel sheet cage. For instance, 23088 CAK/C3W33 brings together a tapered bore, C3 clearance and lubrication provisions. Other suffixes can appear, such as W507 for a special coating or C08 for a special clearance.
These bearings suit high-load positions where misalignment is possible. Typical installations include speed reducers, cement and mining mills, vibrating screens, pulp and paper machines, steelmaking equipment, cranes and conveyors, as well as food processing and aggregate plants. Their capacity for combined loads and their self-aligning behavior make them a fit for equipment exposed to vibration or shaft deflection.
Selection comes down to load type (radial, axial or combined), rotation speed and the operating environment. Internal clearance C3, C4 or C5 is matched to working temperature and mounting fit: higher temperature or more interference calls for greater clearance. Sealing may be open or with seals, depending on contamination. Lubrication, grease or oil, must follow the correct intervals. Even though the bearing self-aligns, initial alignment still matters, since poor mounting shortens service life. Follow the manufacturer's instructions for mounting and axial fixing.
Equivalents exist. Other brands offer spherical roller bearings with a tapered bore and similar suffixes under their own nomenclatures; a 23092 CAK/C3W33, for example, may cross to FAG, NSK or NTN, but the part numbers differ. Before replacing, verify the critical dimensions (bore, outer diameter, width) along with clearance and lubrication details. A similar part number from another brand is not automatically the same part, so check interchange tables or ask a specialist.

Frequently asked questions
- SKF 23088 CAK/C3W33 bearing: what are its dimensions?
- SKF 23088 CAK/C3W33 measures 440 mm across the bore and 650 mm across the outside diameter; its width is 157 mm (440 x 650 x 157 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23088.
- What does the C3 suffix mean on an SKF bearing?
- C3 indicates more internal radial clearance than standard. It is selected when the bearing runs at high temperature or uses interference fits that reduce clearance. C4 and C5 indicate progressively greater clearances.
- Is this bearing self-aligning?
- Yes. SKF spherical roller bearings in the CAK/C…W… series are self-aligning. The two rows of rollers compensate for angular misalignment between shaft and housing, which eases mounting and supports service life.
- How do I choose between a tapered bore and a cylindrical bore?
- A tapered bore (CAK) works with adapter sleeves or tapered shafts, simplifying mounting and allowing radial clearance adjustment. A cylindrical bore needs an interference fit on the shaft. The decision depends on equipment design and mounting practice.
