Decoding SKF 22208 K/C3W33VA9A1
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- K/C3W33VA9A1Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22208 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 22208 K/C3W33VA9A1 measures 40 mm across the bore and 80 mm across the outside diameter; its width is 23 mm (40 x 80 x 23 mm).

For maintenance and purchasing teams dealing with combined radial and axial loads, the SKF 222 K/C3W33VA9A1 series offers a self-aligning spherical roller bearing design. The two rows of rollers handle misalignment between shaft and housing, while the tapered bore and specific suffixes adapt the bearing to demanding industrial setups.
The part number breaks down into distinct elements. The 222 identifies the bearing type and dimensional series. The K indicates a tapered bore with 1:12 taper, allowing mounting on a tapered shaft or adapter sleeve. C3 denotes increased internal radial clearance, W33 means a lubrication groove and holes in the outer ring, and VA9A1 refers to a special execution with a brass cage and other particularities. For instance, 22205 K/C3W33VA9A1 has a 25 mm inner diameter, while 22212 K/C3W33VA9A1 measures 60 mm. These codes let you quickly match the bearing to your application.
Typical uses span mining, cement, steel, paper, cranes, conveyors and vibrating machinery. In the US, you will find them in food processing, petrochemical and aggregate operations, as well as industrial fans, large centrifugal pumps and gearboxes. Their self-aligning capability suits long shafts or assemblies where perfect alignment is difficult to maintain.
Selection depends on radial and axial load, speed, lubrication and mounting method. The K tapered bore simplifies radial clearance adjustment during installation. C3 clearance is appropriate for high temperatures or interference fits. W33 enables relubrication through the outer ring. The VA9A1 brass cage provides guidance and robustness in severe conditions. Always check alignment and sealing for reliable operation.
Interchangeability is possible with other brands that follow the same international designation, such as FAG, NSK, NTN or Timken, provided dimensions and execution match. Suffixes K, W33 and C3 are industry standard, but VA9A1 is specific to SKF, so consult us for an exact equivalent.

Frequently asked questions
- SKF 22208 K/C3W33VA9A1 bearing: what are its dimensions?
- SKF 22208 K/C3W33VA9A1 measures 40 mm across the bore and 80 mm across the outside diameter; its width is 23 mm (40 x 80 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22208.
- What does the K suffix mean in an SKF bearing?
- The letter K indicates a tapered bore with 1:12 taper, which allows mounting on a tapered shaft or an adapter sleeve and facilitates adjustment of internal radial clearance during installation.
- What is the W33 suffix for?
- W33 indicates that the outer ring has a groove and three lubrication holes, enabling relubrication from the housing and helping extend service life in high-temperature or contaminated environments.
- What advantages does the VA9A1 cage have?
- VA9A1 identifies a special execution with a brass cage, which offers greater resistance and better roller guidance. It is suitable for applications with high loads, moderate speeds or severe working conditions.
