Decoding SKF 3306 A-2Z/C3MT33
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 06Bore
- Bore 30 mm (06 × 5).
- A-2Z/C3MT33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3306 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3306 A-2Z/C3MT33 measures 30 mm across the bore and 72 mm across the outside diameter; its width is 30.2 mm (30 x 72 x 30.2 mm).

Double row angular contact bearings from SKF handle radial and axial loads in both directions, thanks to their two ball rows and contact angle. MR Industrial Accessories LLC supplies these bearings to industrial plants across the United States and Latin America, where equipment demands rigidity and precision.
The part number tells you a lot. Take 3204 A-2Z/C3MT33: 3204 is the series and size, A is an internal design variant, 2Z means two protective shields, C3 is the internal radial clearance, and MT33 is the lubricant type. In 3305 A-2Z/C3MT33, the 33 prefix points to a different dimensional series. Reading these codes correctly is the first step in choosing a bearing that fits the shaft and housing.
These bearings appear in food, chemical, petrochemical and process plants, often at moderate speeds and high temperatures. You will find them in centrifugal pumps, compressors, industrial fans, conveyor belts and machine tools. Because they take axial loads in both directions, they suit shafts that need high precision and rigidity.
Selection depends on radial and axial load, rotational speed and the surrounding conditions. The 2Z shield keeps out dust and moisture, while C3 clearance works well with interference fits or elevated temperatures. MT33 grease is a high-quality lubricant for long life. During mounting, align the bearing precisely and avoid impacts that could damage the raceways.
Other manufacturers may list bearings with similar designations. Always check dimensions and load capacities before substituting. SKF is a globally recognized brand, and MR Industrial Accessories LLC includes it in its catalog. If you are replacing a bearing, contact us to confirm interchangeability and prevent premature failures.

Frequently asked questions
- SKF 3306 A-2Z/C3MT33 bearing: what are its dimensions?
- SKF 3306 A-2Z/C3MT33 measures 30 mm across the bore and 72 mm across the outside diameter; its width is 30.2 mm (30 x 72 x 30.2 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3306.
- What does the C3 suffix mean in these bearings?
- C3 indicates a greater internal radial clearance than standard. It is used when the bearing operates at elevated temperatures or with interference fits, to compensate for thermal expansion and avoid excessive preload.
- What is the 2Z seal for?
- The 2Z seal consists of two metal shields that protect the bearing against the ingress of dust and moisture. It suits applications without direct contact with liquids but where some protection is required.
- Can I replace an SKF bearing with another brand?
- Yes, if dimensions and load capacities are equivalent. Verify the complete designation and consult a specialist to ensure compatibility and equipment performance.
