How to read SKF 3308 A-2Z/C3MT33
- 33Series
- Double row angular contact ball bearings, 33 series. For the same bore, each series has a different outside diameter and width.
- 08Bore
- 40 mm bore: 08 × 5.
- A-2Z/C3MT33Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
3308 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

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 and a contact angle enables superior performance in applications requiring high rigidity and precision. MR Accesorios Industriales supplies this line for industrial equipment that demands reliability and durability.
The designation of these bearings follows a scheme combining numbers and letters. For example, in 3204 A-2Z/C3MT33, the 3204 indicates the series and size; the A may indicate an internal design variant; 2Z refers to two protective shields; C3 is the internal radial clearance; and MT33 is the lubricant type. In 3305 A-2Z/C3MT33, the prefix 33 corresponds to another dimensional series. Understanding these codes helps select the right bearing for each piece of equipment.
These bearings are used in industries such as food, chemical, petrochemical and process industries, where equipment operates at moderate speeds and high temperatures. Typical applications include centrifugal pumps, compressors, industrial fans, conveyor belts and machine tools. Their ability to support axial loads in both directions makes them ideal for shafts requiring high precision and rigidity.
To select the correct bearing, consider radial and axial load, rotational speed and environmental conditions. The 2Z seal protects against dust and moisture, while C3 clearance is suitable for interference fits or elevated temperatures. MT33 lubrication is a high-quality grease for long life. During mounting, ensure precise alignment and avoid impacts that could damage the raceways.
Regarding equivalents, other manufacturers may offer bearings with similar designations, but it is essential to verify dimensions and load capacities. SKF is a globally recognized brand, and MR Accesorios Industriales supplies it as part of its catalog. If you need to replace a bearing, consult us to validate interchangeability and avoid premature failures.

Frequently Asked Questions
- What are the dimensions of the SKF 3308 A-2Z/C3MT33 bearing?
- The SKF 3308 A-2Z/C3MT33 bearing has a 40 mm bore, a 90 mm outside diameter and a 36.5 mm width (40 x 90 x 36.5 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 3308.
- What does the C3 suffix mean in these bearings?
- The C3 suffix indicates a greater internal radial clearance than standard. It is used when the bearing will operate 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 is suitable for applications where there is no direct contact with liquids, but some protection is required.
- Can I replace an SKF bearing with another brand?
- Yes, provided the dimensions and load capacities are equivalent. It is important to verify the complete designation and consult a specialist to ensure compatibility and equipment performance.
