NTN angular contact ball bearings are components designed to withstand combined radial and axial loads. Their design with offset raceways allows angular contact between balls and raceways, which gives them a higher axial capacity than deep groove ball bearings. They are used in applications where shafts must be guided with precision and thrust must be supported in one direction, such as machine tool spindles, pumps, compressors and gearboxes.

The designation of these NTN bearings is read by series and suffixes. The 70 series corresponds to thin-section angular contact bearings, with a contact angle of 15° or 25° depending on the case. The CT suffix indicates a design with a polyamide cage and a 15° contact angle, while the final B indicates a variant with a specific preload or internal clearance. For example, the 7030CT1B has a bore diameter of 150 mm, and the 7040CT1B of 200 mm. These part numbers allow you to quickly identify the main characteristics.

In Argentine industry, these bearings are used in machine tool spindles, milling machine heads, centrifugal pumps, screw compressors and speed reducers. They are also present in mining, steelmaking and cement plant equipment, where axial loads are significant. Their ability to work at high speeds makes them suitable for electric motors and turbines. MR Accesorios Industriales sells this line to supply maintenance workshops and factories that need reliable spare parts.

To select the correct bearing, take into account the direction of the axial load, the rotation speed and the type of lubrication. These bearings are usually mounted in pairs, with adjusted preload, to eliminate axial clearance and increase the rigidity of the assembly. Sealing can be open or with protective plates, depending on the environment. Alignment between the housings is critical to avoid additional stresses. Lubrication can be grease or oil, and must be chosen according to the temperature and operating speed.

Equivalences between brands are possible if the main dimensions and the contact angle are compared. An NTN bearing of the 70 series can be replaced by one from another brand with the same basic designation, but always verify the tolerance and internal clearance. Suffixes may vary between manufacturers, so it is important to confirm the characteristics with the complete part number. If you have the part number of another brand, we can indicate the compatible alternative.
