SKF angular contact bearings are precision components designed to support combined radial and axial loads in a single direction. Their angular contact raceway design allows high speeds and rigidity, making them ideal for applications requiring accuracy and durability. At MR Accesorios Industriales we supply the brand SKF.

The designation of these bearings follows a standardized system. For example, in 7020 ACD/P4ATBTC, the prefix 70 indicates the dimension series, 20 the size code, ACD the contact angle and internal design, P4A the precision class, and TBTC the set type (universal triplex). In 71940 ACD/P4ATBTC, 719 corresponds to the thin-section series. These suffixes provide information on key characteristics such as precision, arrangement and load capacity.

These bearings are used in machine tool spindles, pumps, compressors, electric motors and power transmission equipment. In Argentine industry, they are common in metalworking, automotive and food applications, where high precision and reliability are required. Their ability to support combined loads makes them suitable for tandem, back-to-back or face-to-face arrangements, depending on the equipment configuration.

To select correctly, consider the magnitude and direction of the loads, the rotational speed and the environmental conditions. Sealing or protection is crucial: open bearings require external lubrication and cleanliness, while sealed versions offer greater lubricant retention. Internal clearance and preload must be adjusted according to the application. During mounting, ensure precise alignment and avoid impacts that damage the raceways. Proper lubrication extends service life.

Regarding equivalences, SKF angular contact bearings can be interchanged with those from other brands that follow the same dimensional and precision designation, such as FAG, NSK or NTN, but always verify the tolerances and contact angle. Not all suffixes are equivalent between manufacturers. For replacements, it is essential to compare the technical specifications and consult a specialist to avoid premature failures.
