SKF spherical roller bearings are self-aligning components with two rows, designed to withstand high radial loads and axial loads in both directions, even with misaligned shafts. Their self-aligning design makes them ideal for applications with shaft deflection or imprecise mounting. At MR Accesorios Industriales we supply the SKF brand, with decades of experience in the field. If you need a robust solution for demanding machinery, this type of bearing is a safe choice.
The designation of these bearings follows a scheme that combines numbers and letters. For example, in 22324 CCKJA/W33VA405, the 223 indicates the dimension series, 24 the size, and CCKJA the internal design with stamped steel cage, tapered bore and other characteristics. The suffix W33 indicates the presence of a groove and lubrication holes in the outer ring, while VA405 identifies a particular specification, often linked to tolerances or heat treatment. Knowing these codes allows you to select the right bearing for your equipment.
These bearings are used in industries such as cement, mining, steel, paper and material handling. In Argentina, they are common in mills, crushers, conveyor belts, industrial fans and paper machines. Their ability to withstand heavy loads and misalignment makes them suitable for dusty and high-vibration environments. MR Accesorios Industriales supplies them to plants and workshops throughout the country.
When selecting a spherical roller bearing, take into account radial and axial load, rotational speed and environmental conditions. Sealing is key: if there is contamination, choose variants with seals or protections. Lubrication must be suitable, with grease or oil depending on the application. Mounting requires alignment and correct fitting of the tapered bore, often with an adapter sleeve. Appropriate internal clearance prevents overheating and extends service life.
Regarding equivalences, other manufacturers offer bearings with similar designations, but they are not always directly interchangeable. The letters and numbers may vary in meaning, and tolerances or clearances may differ. Therefore, always verify the technical specifications before replacing one brand with another. At MR Accesorios Industriales we can advise you on compatibility and the options available in SKF.

Frequently Asked Questions
- What are the dimensions of the SKF 22338 CCKJA/W33VA405 bearing?
- The SKF 22338 CCKJA/W33VA405 bearing has a 190 mm bore, a 400 mm outside diameter and a 132 mm width (190 x 400 x 132 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 22338.
- What does the W33 suffix mean in these bearings?
- The W33 suffix indicates that the bearing has a groove and three lubrication holes in the outer ring. This facilitates relubrication and improves lubricant distribution, especially in applications with high loads or moderate speeds.
- Are they suitable for misaligned shafts?
- Yes, spherical roller bearings are self-aligning. They can compensate for angular misalignment without generating significant additional loads. This makes them ideal for long shafts or assemblies where perfect alignment is difficult to achieve.
- How do I choose between a bearing with a tapered bore and one with a cylindrical bore?
- The tapered bore (suffix K) allows the bearing to be mounted with an adapter sleeve, which facilitates fitting and removal. The cylindrical bore is mounted directly on the shaft. The choice depends on the shaft design and the mounting requirements.
