How to read SKF 3220 A/W64
- 32Series
- Double row angular contact ball bearings, 32 series. For the same bore, each series has a different outside diameter and width.
- 20Bore
- 100 mm bore: 20 × 5.
- A/W64Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
3220 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF double row angular contact bearings are components designed to support combined radial and axial loads in both directions. Their construction with two rows of balls at opposing contact angles enables superior performance in applications requiring high precision and rigidity. They are ideal for equipment operating at moderate and high speeds, such as pumps, compressors and machine tools. At MR Accesorios Industriales we sell them as part of our SKF bearing line.
The designation of these bearings follows the SKF system: the basic number indicates the size and series. The prefix 32 corresponds to the double row series, followed by two digits indicating the bore diameter. The suffix A indicates an optimized internal design, and W64 refers to a special lubrication. Knowing these codes makes it easier to identify and select the right bearing for each application.
These bearings are used in a wide variety of industries in Argentina, such as food, chemical, petrochemical and manufacturing. They are found in centrifugal pumps, screw compressors, industrial fans, machine tools and power transmission equipment. Their ability to support axial loads in both directions makes them suitable for applications where load reversal is frequent. They are also used in milling machine and drilling machine spindles, where precision and rigidity are critical.
To correctly select a double row angular contact bearing, it is essential to consider the magnitude and direction of the loads, the operating speed and the environmental conditions. Mounting requires precise alignment between the shaft and the housing, since these bearings are sensitive to misalignment. Lubrication must be appropriate according to the indicated suffix; for example, W64 specifies a particular grease. Sealing is also key to prevent contamination and lubricant loss, extending the bearing's service life.
Regarding equivalences and interchangeability, SKF double row angular contact bearings can be replaced by products from other brands that follow the same dimensional and capacity designation. However, it is important to verify tolerances and internal clearance, as they may vary between manufacturers. We always recommend consulting our technical team to ensure compatibility and optimal performance in your specific application.

Frequently Asked Questions
- What are the dimensions of the SKF 3220 A/W64 bearing?
- The SKF 3220 A/W64 bearing has a 100 mm bore, a 180 mm outside diameter and a 60.3 mm width (100 x 180 x 60.3 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3220.
- What does the suffix A mean in these bearings?
- The suffix A indicates an optimized internal design, which may include changes in raceway geometry or contact angle to improve performance and load capacity.
- What is W64 lubrication for?
- W64 is an SKF code that identifies a special high-quality grease, suitable for applications requiring resistance to high temperatures and loads. It provides long-lasting and reliable lubrication.
- How do I know if I can replace an SKF bearing with another brand?
- You must verify that the main dimensions, load capacity and internal clearance are equivalent. Consult our technical team to ensure interchangeability and avoid premature failures.
