Decoding SKF 3206 ATN9/VQ537
- 32Series
- Double row angular contact ball bearings, 32 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- ATN9/VQ537Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3206 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3206 ATN9/VQ537 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 23.8 mm (30 x 62 x 23.8 mm).

For assemblies that need to handle radial and axial forces in both directions, the SKF double row angular contact bearing is a common choice. Its two rows of balls run on inclined raceways, which gives the bearing rigidity and load capacity for precision work. Machine tool spindles, pumps and gearboxes are typical examples. This bearing is part of the SKF line available from MR Industrial Accessories LLC.
The part number 3206 ATN9/VQ537 follows a standard coding system. The first digits give the type and dimension series; series 32 identifies a double row bearing with a particular design. The suffixes carry the rest of the specification: ATN means a polyamide cage reinforced with fiberglass and an optimized internal design, while /VQ537 denotes a defined clearance or preload specification set by the manufacturer. Reading these codes correctly helps you match the bearing to the application.
These bearings appear in equipment where precision and load capacity matter. Machine tool spindles, milling machine heads, gear pumps, compressors and speed reducers are common locations. They also show up in power transmission equipment and in automotive applications that require high rigidity. Because they accept axial loads in both directions, they suit arrangements that need exact shaft positioning.
When selecting a double row angular contact bearing, consider the load it will carry, the rotation speed and the operating environment. Internal clearance or preload has a direct effect on rigidity and service life, so confirm it before mounting. Installation calls for precise alignment and, in many cases, a press fit on the shaft or in the housing. Grease or oil lubrication and effective sealing against contaminants are also important for long-lasting performance.
SKF bearings of this type can be replaced by products from other brands that follow the same dimensional and suffix designation. Tolerances and internal clearance can differ between manufacturers, so verify them before substituting. A specialist can confirm compatibility and expected performance in your application.

Frequently asked questions
- SKF 3206 ATN9/VQ537 bearing: what are its dimensions?
- SKF 3206 ATN9/VQ537 measures 30 mm across the bore and 62 mm across the outside diameter; its width is 23.8 mm (30 x 62 x 23.8 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3206.
- What does the ATN suffix mean in an SKF bearing?
- ATN indicates a polyamide cage reinforced with fiberglass and an optimized internal design. This cage reduces weight and improves behavior at high speeds, and it resists temperature and common lubricants.
- Does this bearing accept axial loads in both directions?
- Yes. The double row angular contact design supports axial loads in both directions in addition to radial loads. That makes it suitable for applications requiring high rigidity and precise shaft control.
- How do I choose the right internal clearance for my application?
- Internal clearance or preload depends on working conditions such as speed, temperature and load type. Precision applications usually need a light preload, while high speeds may call for a larger clearance. Consult our technical team for a specific recommendation.
