SKF tapered roller bearings with the X/DF suffix are assemblies of two paired bearings mounted face-to-face. This arrangement allows them to withstand radial and axial loads in both directions, as well as tilting moments. They are used in applications requiring high rigidity and load capacity, such as gearboxes, wheel axles and mining equipment. MR Accesorios Industriales sells this line as an official brand.

The designation of these bearings combines the basic series number with the suffix X/DF. For example, in 31322 X/DF, 31322 identifies the size and dimension series, while X indicates that the external dimensions are modified to allow universal mounting, and DF indicates that it is a pair of bearings paired in a face-to-face arrangement. This configuration is suitable for axial loads in both directions and moments. Other examples in the line are 32017 X/DF and 32028 X/DF, which share the same designation criteria.

These bearings are used in industries such as mining, cement, steel and material handling. In Argentina, they are commonly found in speed reducers, gearboxes, conveyor roller shafts, mills and crushing equipment. They also appear in agricultural and road machinery, where combined loads and severe conditions demand robust, high-capacity bearings. Their paired design simplifies mounting and guarantees controlled internal clearance.

To correctly select an X/DF bearing, take into account the radial and axial load it must withstand, the rotational speed and the environmental conditions. It is essential to verify the sealing: these bearings are usually mounted with external seals to retain lubricant and exclude contaminants. Lubrication can be with grease or oil, depending on the application. During mounting, ensure precise shaft alignment and proper fit in the housing to avoid additional loads. The internal clearance is pre-adjusted at the factory, so no subsequent calibration is required.

Regarding equivalences, SKF X/DF bearings can be interchanged with products from other brands that follow the same international designation. However, it is important to verify dimensions and tolerances, as minor variations may exist between manufacturers. Always consult a specialist before replacing a bearing, especially in critical applications. MR Accesorios Industriales can advise you on compatibility and available options.
