Decoding SKF 22338 CCJA/W33VA406
- 223Series
- Spherical roller bearings, 223 series. Series differ in outside diameter and width even when the bore is the same.
- 38Bore
- Bore 190 mm (38 × 5).
- CCJA/W33VA406Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22338 is the standard ISO basic designation, which sets the bearing type, series and bore.

For vibrating screens, crushers and similar equipment, SKF spherical roller bearings in the CCJA/W33VA405 series are built to handle combined loads and misalignment. They have two rows of rollers, a stamped steel cage and a lubrication groove with holes in the outer ring. MR Industrial Accessories LLC supplies these bearings to customers throughout the United States and Latin America, and our team can help you confirm the right reference for your application.
Reading the code helps you understand what you are ordering. CCJA refers to the internal design: a stamped steel cage that is roller-guided and centered on the inner ring. W33 means the outer ring has a circumferential groove and three lubrication holes. VA405 identifies a special execution for vibrating duties, with defined tolerances and radial clearance. A typical example is 22324 CCJA/W33VA405, which belongs to the 223 series and has a bore diameter of 120 mm. Other VA suffixes use the same base but may differ in surface treatment or clearance.
These bearings are common in equipment that sees constant vibration and shock: vibrating screens, sieves, feeders and compaction machines. You will also find them in crushers, mills and conveyors across mining, cement and aggregates operations. Their two-row roller arrangement lets them take high radial loads as well as axial loads in both directions, while compensating for misalignment between shaft and housing.
Correct selection starts with the load case: radial and axial load, rotational speed and the vibration level of the machine. Internal radial clearance must suit the mounting interference and operating temperature; in vibrating applications, a larger clearance often offsets thermal expansion. Lubrication matters just as much. The W33 groove makes relubrication easier, but the grease or oil still has to match speed and temperature. Fit on the shaft and housing, and alignment between housings, also affect service life.
Interchangeability is possible with spherical roller bearings from other brands that carry similar designations, but always check tolerances, clearance and lubrication requirements. Suffixes do not always mean the same thing across manufacturers; an SKF VA, for instance, may have a different clearance than a competitor's equivalent. Dimensional interchangeability is generally maintained within the same ISO series, yet internal features can vary. Use the manufacturer's tables or ask for technical guidance before substituting.

Frequently asked questions
- SKF 22338 CCJA/W33VA406 bearing: what are its dimensions?
- SKF 22338 CCJA/W33VA406 measures 190 mm across the bore and 400 mm across the outside diameter; its width is 132 mm (190 x 400 x 132 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22338.
- What does the VA405 suffix mean on an SKF bearing?
- VA indicates a special execution for vibrating applications, with tolerances and radial clearance adapted to shock loads and misalignment. It is not a universal code; other manufacturers may use their own designations. Ask us if you need help with an equivalent.
- How often should these bearings be lubricated?
- The interval depends on speed, temperature and environment. In vibrating equipment, follow the manufacturer's maintenance plan. The W33 groove facilitates relubrication, but always verify the lubricant type and quantity.
- Can I replace an SKF bearing with another brand?
- Yes, if dimensions and radial clearance match. However, special suffixes such as VA may vary between brands. Before substituting, compare the technical specifications or send us the original part number for advice.
