The angular contact ball bearing is a component designed to withstand combined radial and axial loads. Its design with offset raceways allows angular contact between the balls and the raceways, giving it a higher axial load capacity than a deep groove ball bearing. It is used in applications requiring high precision and rigidity, such as machine tool spindles, pumps, compressors and gearboxes. At MR Accesorios Industriales we sell the NTN line for the Argentine market.

The designation of these bearings follows a numerical scheme that begins with the bearing type. For example, the 7000 series corresponds to single-row bearings with a 15° or 25° contact angle, while the 7200 series has a larger angle, and the 7300 series even more. The suffixes indicate additional characteristics: C for a 15° contact angle, AC for 25°, B for 40°. Letters such as P for polyamide cage, G for brass cage, or DB, DF, DT for paired mountings may also appear. Learn more about these variants by asking for the full part number.

These bearings are used in industries such as metalworking, food, petrochemical and process industries. In Argentina, they are commonly found in milling machine and CNC lathe spindles, centrifugal pumps, screw compressors, gearboxes and transmission equipment. Their ability to withstand axial loads in one direction makes them ideal for mountings requiring preload and rigidity. MR Accesorios Industriales supplies workshops, factories and industrial maintenance operations throughout the country.

To correctly select an angular contact bearing, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Sealing can be open, with shields (ZZ) or with seals (LLB, LLU), depending on contamination and the need to retain lubricant. Internal clearance and preload are critical: a mounting with inadequate preload can cause overheating. Alignment between supports must be precise, since these bearings are sensitive to misalignment. Lubrication can be grease or oil, depending on speed and temperature.

As for equivalents, NTN angular contact bearings are interchangeable with those of other brands such as SKF, FAG, NSK or Timken, provided the main dimensions and contact angle match. Suffixes may vary between manufacturers, so it is essential to verify the full part number and technical specifications. If you replace a bearing, make sure the new one has the same load capacity and configuration. For an exact equivalent, consult our technical team.
