SKF spherical roller bearings of the CAC/C…W… series are self-aligning components with two rows of rollers, designed to withstand combined loads and angular misalignment. They are used in industrial applications where shaft deflection or mounting errors require self-aligning capability. MR Accesorios Industriales carries this line as a brand, backed by technical experience in the industry.
The designation of these bearings combines the basic size number with suffixes that indicate internal features. For example, in 22252 CAC/C3W33, the prefix 222 identifies the medium-width spherical roller bearing series; CAC defines the cage design and roller guidance; C3 indicates a radial internal clearance greater than normal; and W33 indicates the presence of a lubrication groove and holes in the outer ring. Variants such as C2, C4 or C08 adjust clearance according to the application, while W509 or W513 refer to special lubrication configurations.
These bearings are used in equipment subjected to heavy loads and misalignment, such as conveyor belts, mills, crushers, large centrifugal pumps, industrial fans and pulp and paper machinery. In Argentina, they are common in the cement, mining, steel and oilseed industries, where long shafts or separate supports generate deflections that a rigid bearing would not tolerate. Their self-aligning capability reduces wear and extends the service life of the assembly.
To select correctly, take into account radial and axial load, rotational speed and required internal clearance. The C3 or C4 suffix is chosen when interference fit or operating temperature reduces operating clearance. Lubrication is critical: W33 holes allow relubrication through the outer ring. During mounting, check initial alignment and avoid impacts that could damage the rollers or cage. Mounting with a hydraulic press and controlled heating is recommended.
Regarding equivalences, spherical roller bearings are manufactured under international dimension standards, so the same basic number can usually be interchanged between different brands. However, suffix meanings may vary by manufacturer. Therefore, when looking for a replacement, do not rely on the number alone: verify clearance, cage type and lubrication features. MR Accesorios Industriales can advise you to find the right option within its SKF line.

Frequently Asked Questions
- What are the dimensions of the SKF 23068 CAC/C2W513 bearing?
- The SKF 23068 CAC/C2W513 bearing has a 340 mm bore, a 520 mm outside diameter and a 133 mm width (340 x 520 x 133 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 23068.
- What does the C3 suffix mean on an SKF bearing?
- The C3 suffix indicates a radial internal clearance greater than normal. It is specified when interference fit mounting, thermal differences between rings or operating speed reduce clearance during operation. This prevents insufficient residual clearance that could damage the bearing.
- When should you choose a bearing with the W33 suffix?
- The W33 suffix indicates that the outer ring has a groove and three lubrication holes. It is useful in applications where frequent relubrication is needed without dismounting the bearing, such as in mining, cement or paper equipment subjected to contaminated environments and high temperatures.
- Are SKF bearings of this series interchangeable with other brands?
- Spherical roller bearings follow international dimension standards, so the basic number usually matches between manufacturers. However, suffixes may have different meanings. Before replacing, verify internal clearance, cage and lubrication. Consult MR for a safe equivalence.
