SKF spherical roller bearings are self-aligning bearings with two rows of rollers, designed to support radial and axial loads in both directions, even with misalignment between shaft and housing. This series with tapered bore and specific suffixes is used in demanding applications where high load capacity and rigidity are required. MR Accesorios Industriales sells this line for the Argentine market.
The designation of this series is read as follows: 222 indicates the type and dimensional series; K means tapered bore (taper 1:12); C3 is the increased internal radial clearance; W33 indicates that it incorporates a lubrication groove and holes in the outer ring; VA9A1 corresponds to a special execution with brass cage and other particularities. For example, 22205 K/C3W33VA9A1 is a bearing with 25 mm inner diameter, while 22212 K/C3W33VA9A1 has 60 mm. These codes allow you to quickly identify the characteristics of each item.
These bearings are used in mining, cement, steel, paper, cranes, conveyors and vibrating machines. In Argentina, they are common in the food, petrochemical and aggregate processing industries. Their ability to withstand misalignment makes them suitable for long shafts or assemblies where perfect alignment cannot be guaranteed. They are also used in industrial fans, large centrifugal pumps and gearboxes.
To select correctly, take into account the radial and axial load, speed, lubrication and type of assembly. The K tapered bore is mounted on an adapter sleeve or directly on a tapered shaft; this facilitates adjustment of the radial clearance. The C3 suffix indicates a greater than normal clearance, suitable for high temperatures or interference fits. W33 allows relubrication through the outer ring. The VA9A1 brass cage provides resistance and guidance in severe applications. Always verify alignment and sealing.
Regarding equivalences, SKF bearings of this series can be interchanged with those of other brands that follow the same international designation, such as FAG, NSK, NTN or Timken, as long as dimensions and execution match. The suffixes K, W33 and C3 are standard in the industry, but VA9A1 is specific to SKF, so an exact equivalence must be consulted.

Frequently Asked Questions
- What are the dimensions of the SKF 22211 K/C3W33VA9A1 bearing?
- The SKF 22211 K/C3W33VA9A1 bearing has a 55 mm bore, a 100 mm outside diameter and a 25 mm width (55 x 100 x 25 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 22211.
- What does the K suffix mean in an SKF bearing?
- The letter K indicates that the bearing has a tapered bore with 1:12 taper. This allows it to be mounted on a tapered shaft or an adapter sleeve, which facilitates adjustment of the internal radial clearance during installation.
- What is the W33 suffix for?
- W33 indicates that the outer ring has a groove and three lubrication holes. This allows the bearing to be relubricated from the housing, extending its service life in applications with high temperatures or contaminated environments.
- What advantages does the VA9A1 cage have?
- VA9A1 identifies a special execution with brass cage, which offers greater resistance and better roller guidance. It is suitable for applications with high loads, moderate speeds or severe working conditions.
