Decoding SKF 22205/W33VA9A1
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 05Bore
- Bore 25 mm (05 × 5).
- W33VA9A1Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22205 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 22205/W33VA9A1 measures 25 mm across the bore and 52 mm across the outside diameter; its width is 18 mm (25 x 52 x 18 mm).

SKF 222 series spherical roller bearings are self-aligning units that use two rows of rollers to handle heavy radial loads and angular misalignment. Because the outer ring can rotate relative to the inner ring, they compensate for mounting inaccuracies or shaft deflection. You will find them in equipment where perfect alignment is difficult to maintain, such as conveyors, mills, and paper machines.
The part number breaks down into three elements. The base number 222 denotes the medium-width spherical roller bearing series, followed by a size code. The suffix W33 means the outer ring has a lubrication groove and three holes, so grease can be applied through the housing. The suffix VA9A1 indicates a special execution with tolerances and internal clearance set by the manufacturer for specific applications. For instance, 22205/W33VA9A1 combines the 222 series, size 05, and both suffixes. Always confirm what each suffix means before you order a replacement.
These bearings appear in cement, mining, steel, paper, and food processing plants. They are common in belt conveyors, ball mills, crushers, dryers, mixers, and paper machines, as well as in large pumps and fans. Their capacity for combined loads and misalignment makes them suitable for long shafts or assemblies that lack full structural rigidity.
When selecting a bearing, consider radial and axial loads, rotational speed, and lubrication method. If the bearing has the W33 suffix, the housing must have lubrication passages that line up with the holes in the outer ring. The VA9A1 internal clearance must suit the operating temperature and shaft fit. During installation, verify alignment and avoid impacts that could damage rollers or raceways. Proper lubrication and effective sealing help extend service life.
Spherical roller bearings are identified by their numeric designation and standard suffixes. Other brands may offer similar products, but the extra letters can differ. Do not assume that a code from another manufacturer is identical; always compare dimensions, clearance, and lubrication requirements. MR supplies SKF as one of its brands and can advise you on interchangeability.

Frequently asked questions
- SKF 22205/W33VA9A1 bearing: what are its dimensions?
- SKF 22205/W33VA9A1 measures 25 mm across the bore and 52 mm across the outside diameter; its width is 18 mm (25 x 52 x 18 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22205.
- What does the W33 suffix mean on an SKF bearing?
- W33 means the outer ring has a groove and three lubrication holes. This allows greasing through the housing without disassembly, which simplifies maintenance on hard-to-reach equipment.
- How is VA9A1 different from other executions?
- VA9A1 is a special execution defined by SKF that may include tighter tolerances or a particular internal clearance. It is not a generic code, so consult the technical data sheet to confirm the exact characteristics for your application.
- Can I replace an SKF bearing with another brand?
- Yes, but check dimensions, clearance, and suffixes. Designations do not always match between manufacturers. MR can help you find the correct equivalent for your equipment and operating conditions.
