Decoding SKF 23168 CAC/C3W33
- 231Series
- Spherical roller bearings, 231 series. Series differ in outside diameter and width even when the bore is the same.
- 68Bore
- Bore 340 mm (68 × 5).
- CAC/C3W33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23168 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

SKF CAC/C…W… series spherical roller bearings are self-aligning, double-row components that handle combined loads and angular misalignment. They suit industrial equipment where shaft deflection or mounting inaccuracies call for self-aligning capability. MR Industrial Accessories supplies this line and supports selection by part number.
The part number encodes internal features. In 22252 CAC/C3W33, 222 denotes the medium-width spherical roller bearing series; CAC specifies the cage design and roller guidance; C3 means radial internal clearance above normal; W33 indicates a lubrication groove and holes in the outer ring. Other clearance classes such as C2, C4 or C08 are available, and W509 or W513 designate special lubrication arrangements.
Typical applications include conveyor belts, mills, crushers, large centrifugal pumps, industrial fans, and pulp and paper machinery. These bearings are common in cement, mining, steel and oilseed processing, where long shafts or separate supports produce deflection that a rigid bearing cannot accommodate. Self-aligning capability helps reduce wear and extend assembly service life.
Selection depends on radial and axial load, rotational speed, and required internal clearance. Choose C3 or C4 when interference fits or operating temperature reduce running clearance. Lubrication is critical: W33 holes permit relubrication through the outer ring. During mounting, verify initial alignment and avoid impacts that could damage rollers or cage. Use a hydraulic press and controlled heating.
Because spherical roller bearings follow international dimension standards, the basic number often interchanges across brands. However, suffix meanings can differ. When sourcing a replacement, check clearance, cage type and lubrication features rather than relying on the number alone. MR Industrial Accessories can help identify the correct option within its SKF line.

Frequently asked questions
- SKF 23168 CAC/C3W33 bearing: what are its dimensions?
- SKF 23168 CAC/C3W33 measures 340 mm across the bore and 580 mm across the outside diameter; its width is 190 mm (340 x 580 x 190 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23168.
- What does the C3 suffix indicate on an SKF bearing?
- C3 denotes radial internal clearance greater than normal. It is specified when interference fits, temperature differences between rings, or operating speed reduce clearance during operation, preventing insufficient residual clearance that could damage the bearing.
- When is a W33 suffix appropriate?
- W33 means the outer ring has a groove and three lubrication holes. This is useful when frequent relubrication is needed without dismounting, such as in mining, cement or paper equipment exposed to contaminants and high temperatures.
- Can SKF bearings of this series be replaced by other brands?
- Spherical roller bearings conform to international dimension standards, so the basic number usually matches between manufacturers. However, suffixes may differ in meaning. Before replacing, verify internal clearance, cage and lubrication. Consult MR for a safe equivalence.
