Decoding FAG 3308-DA-MA
- 33Series
- Angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- DA-MASuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3308 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 3308-DA-MA measures 40 mm across the bore and 90 mm across the outside diameter; its width is 36.5 mm (40 x 90 x 36.5 mm).

Angular contact ball bearings in the FAG DA-MA series are built to take radial and axial forces acting in a single direction. The oblique ball-to-raceway contact gives them good axial capacity and stiffness. Machine tools, pumps and gearboxes are common homes for these bearings. MR Industrial Accessories supplies this line to customers in the United States and Latin America.
Reading the part number helps you identify the variant. Take 3308-DA-MA: the base number points to the 33 dimension series, while DA and MA describe internal construction. DA generally means a stamped steel cage and a defined contact angle; MA generally means a machined brass cage for higher speeds and temperatures. These suffixes make it easy to spot the differences between one version and another.
These bearings appear in equipment where radial and axial loads occur together: machine tool spindles, centrifugal pumps, compressors, gearboxes and transmission housings. Mining, cement, food processing and steel operations also rely on them where precision and toughness matter. Because they accept thrust in one direction, they work well in paired or preloaded arrangements, depending on how the equipment is designed.
Selecting the right bearing starts with the axial load direction, the speed of rotation and the operating environment. Choose seals or shields based on contamination levels and whether lubricant retention is needed. Grease or oil lubrication both work, and internal clearance must suit the assembly. Shaft and housing alignment should be correct to prevent parasitic loads. In paired setups, follow the arrangement and preload specified by the manufacturer.
When comparing equivalents from other brands, check that bore, outer diameter and width match, and that the contact angle is the same. Suffixes differ between makers, but the basic designation is often interchangeable. For a replacement, also compare load capacity and limiting speed. If anything is unclear, send our technical team the full part number and the operating conditions.

Frequently asked questions
- FAG 3308-DA-MA bearing: what are its dimensions?
- FAG 3308-DA-MA measures 40 mm across the bore and 90 mm across the outside diameter; its width is 36.5 mm (40 x 90 x 36.5 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3308.
- What do the suffixes DA and MA mean in these bearings?
- DA typically indicates a stamped steel cage and a specific contact angle, while MA typically indicates a machined brass cage for higher speeds and temperatures. These codes identify the internal construction of the bearing.
- Can these bearings be mounted in pairs?
- Yes, angular contact bearings are often mounted in pairs to handle axial loads in both directions. Follow the arrangement (face-to-face, back-to-back) and preload recommended by the manufacturer for proper operation.
- How do I request a quote for these bearings?
- Send us a WhatsApp message with the complete part number, such as 3308-DA-MA, and the quantity. We will reply promptly with the information you need to proceed.
