FAG angular contact bearings are ball bearings with offset raceways that allow them to support radial and axial loads in one direction. They are usually mounted in pairs, face-to-face or matched, to cover combined forces and provide rigidity to the assembly. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, with technical advice to choose the correct configuration according to the equipment and application.

The designation of this line is read by the three- or four-digit series and the suffix that accompanies it. The -M suffix indicates that the bearing incorporates a machined brass cage, suitable for demanding regimes and elevated temperatures. In the series examples, such as 3219-M, 3221-M or 3317-M, the first digits identify the size and type of design; the last two, the dimensional combination. With the complete part number you access the exact variant you need.

These bearings are used in equipment where there are significant axial loads in one direction and high rotational precision is required. In Argentine industry they appear in gearboxes, centrifugal pumps, compressors, machine tool spindles, transmission cases and continuous process equipment. They are also found in mining, cement, steel and food applications, where pair mounting allows the axial load to be distributed and the rigidity of the support to be increased.

To select correctly, you must define the axial load, the radial load, the speed and the internal clearance. Pair mounting is the usual practice: face-to-face for loads in both directions or matched for greater rigidity. Adequate lubrication, sealing according to the environment and careful alignment between supports are key to service life. If the equipment operates at elevated temperature, the machined brass cage identified by the -M suffix is the indicated option.

Regarding equivalences, each manufacturer uses its own nomenclature for angular contact bearings. The same size may have different designations depending on the brand, and the suffixes do not always match. Therefore, it is advisable to compare dimensions, load capacity and cage type before replacing one bearing with another. If you have doubts, send us the original part number and we will help you find the equivalent reference within the brands we supply.
