How to read FAG 3309-DA
- 33Series
- Angular contact ball bearings, 33 series. For the same bore, each series has a different outside diameter and width.
- 09Bore
- 45 mm bore: 09 × 5.
- DASuffix
- FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).
3309 is the standard (ISO) basic designation: it defines the type, the series and the bore.

FAG -DA series angular contact ball bearings are single-row bearings with raceways designed to withstand combined loads: radial and axial in one direction. They are used in applications where rotation precision and axial load capacity are decisive, such as pumps, compressors, gearboxes and spindles. MR Accesorios Industriales sells this line, with technical advice to select the correct code.
The designation of this series is read by the basic number and the -DA suffix. The number indicates the size: the examples 3306-DA, 3307-DA, 3309-DA, 3312-DA, 3313-DA and 3314-DA show the progression of dimensions. The -DA suffix identifies a design variant within FAG's angular contact family, which in this case corresponds to a single-row design. To correctly interpret each code, it is best to consult with the full number and the mounting dimensions.
These bearings are used in rotating equipment that combines radial and axial load: centrifugal pumps, screw compressors, gearboxes, industrial fans and machine tool spindles. In Argentina they are found in food, petrochemical, cement and power generation plants. Their ability to run at high speeds with good rigidity makes them suitable for drives where internal clearance and alignment are critical.
To select the correct bearing, take into account the direction of the axial load, the type of sealing or protection, the internal clearance and the lubrication method. During mounting, it is essential to respect the alignment between shaft and housing, and to apply the preload or clearance specified by the manufacturer. Proper lubrication —grease or oil— and sealing prevent contamination and extend service life. If the bearing is mounted in pairs, verify the arrangement and the axial fit.
Angular contact bearings from different brands may be interchangeable if the main dimensions, contact angle and clearance match. However, the basic number alone is not enough: tolerances, load capacity and sealing configuration must be compared. To find the equivalent from another brand, send the full code and the working conditions, and we will guide you with no obligation.
