The NTN BST series angular contact thrust ball bearing is a component designed to support axial loads in one direction, with high precision and rigidity. It is used in machine tool spindles, rotary tables and precision equipment where a compact and exact assembly is required. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and helps you select the right code for your application.

The BST series designation is read as a code combining the bore diameter and the outer diameter. For example, BST17X47 indicates a bearing with a 17 mm bore and 47 mm outer diameter; BST20X47 has a 20 mm bore and 47 mm outer diameter; BST25X62 corresponds to a 25 mm bore and 62 mm outer diameter. Any suffixes that may appear in the designation provide information about the internal design, preload or sealing, depending on the specific configuration. To correctly interpret each code, consult us with the complete number.

These bearings are used in main spindles of milling machines, grinding machines and machining centers, as well as in precision tables and measuring equipment. In Argentine industry, they are common in the metalworking, automotive and machine tool sectors, where accuracy and the ability to support axial loads are critical. They are also found in indexing devices and positioning systems requiring high repeatability.

To select the right BST thrust ball bearing, take into account the axial load it must support, the rotational speed and the lubrication conditions. Mounting requires precise alignment between the shaft and the housing, as these bearings are sensitive to misalignment. Lubrication can be with grease or oil, depending on the application, and sealing will depend on the working environment. It is essential to respect the mounting tolerances and the preload indicated for each case.

NTN angular contact thrust ball bearings can be interchanged with those of other brands that follow the same dimensional nomenclature, such as SKF, FAG or NSK, provided the main dimensions and load conditions match. However, internal characteristics may vary between manufacturers, so it is advisable to verify the equivalence before replacing. If you have another brand's code, we can help you find the NTN equivalent.
