SKF tapered roller bearings with the /DF suffix are matched pairs of two bearings mounted with their wide faces facing each other, forming a self-aligning arrangement that accommodates angular misalignment. They are used in applications with combined radial and axial loads, such as gearboxes, machine tool spindles and transmission equipment. MR Accesorios Industriales supplies this SKF line, an official brand that MR carries, with more than 80 years of experience in the field.

The designation of these bearings follows the SKF system: the basic number indicates the series and size, and the suffix /DF indicates that it is a matched pair of tapered rollers with angular contact in a self-aligning arrangement. For example, 30220/DF corresponds to a bearing of the 30220 series mounted as a pair; 31306/DF is a matched pair of the 31306 series. The /DF suffix does not change the dimensions of the individual bearing, but defines the assembly as a unit that operates with the wide faces facing each other.

These bearings are used in industries such as metallurgy, cement, mining and machine tools. In Argentina, they are common in speed reducers, main spindles of milling machines and lathes, rolling mill roll shafts and gear transmission equipment. Their ability to support radial and axial loads in both directions makes them suitable for assemblies requiring rigidity and precision, such as bevel gearboxes or drive shafts.

To select a /DF bearing, take into account the radial and axial load that the assembly must support, the rotational speed and the lubrication conditions. Mounting requires careful alignment of the facing faces and adequate preload to avoid excessive clearance. Sealing and lubrication are critical: in contaminated environments, additional seals and high-viscosity lubricant are recommended. Cooling also affects service life, especially in high-speed applications.

Regarding equivalences, SKF bearings with the /DF suffix can be interchanged with products from other brands that offer similar configurations of opposed tapered pairs, such as the /DB or /DF suffixes from other manufacturers. However, dimensions and tolerances may vary, so it is always advisable to verify the complete part number and technical specifications before replacing. MR Accesorios Industriales can advise you on interchangeability without compromising performance.
