FAG DA-MA series angular contact bearings are ball bearings with raceways designed to support radial and axial loads in one direction. Their construction allows an oblique contact between balls and raceways, providing high axial load capacity and rigidity. They are used in applications requiring precision and reliability, such as machine tools, pumps and gearboxes. MR Accesorios Industriales supplies this line as a brand throughout Argentina.

The designation of these bearings is interpreted as follows: the base number indicates the dimension series, and the suffixes DA and MA provide construction features. For example, 3308-DA-MA corresponds to a bearing of the 33 series with suffixes DA and MA. The suffix DA usually indicates a design with stamped steel cage and a specific contact angle, while MA indicates a machined brass cage, suitable for high speeds and temperatures. These codes allow quick identification of the particularities of each variant.

In Argentine industry, these bearings are used in equipment that combines radial and axial loads: machine tool spindles, centrifugal pumps, compressors, gearboxes and transmission cases. They are also present in mining, cement, food and steel applications, where robustness and precision are critical. Their ability to support axial thrust in one direction makes them ideal for paired or preloaded arrangements, depending on the equipment design.

To correctly select an angular contact bearing, take into account the direction of the axial load, the rotation speed and the environmental conditions. Sealing or shield plates should be chosen according to contamination and the need for lubricant retention. Lubrication can be grease or oil, and the internal clearance must be adjusted to the assembly. Alignment between housing and shaft is essential to avoid parasitic loads. In paired arrangements, respect the arrangement and preload indicated by the manufacturer.

When looking for equivalents from other brands, verify that the main dimensions (bore, outer diameter and width) and the contact angle match. Suffixes may vary between manufacturers, but the basic designation is usually compatible. For replacements, it is advisable to also compare the load capacity and the limiting speed.
