The NTN BST series covers angular contact thrust ball bearings built to handle axial loads in a single direction, with the precision and rigidity that machine tool spindles, rotary tables and other exacting assemblies demand. MR Industrial Accessories supplies this series to maintenance and purchasing teams across the United States and Latin America, and can help you match the right code to your application.

Reading a BST code is straightforward once you know the pattern: the numbers give bore and outer diameter. BST17X47 is a 17 mm bore with a 47 mm outer diameter, BST20X47 is a 20 mm bore with a 47 mm outer diameter, and BST25X62 is a 25 mm bore with a 62 mm outer diameter. Suffixes, when present, point to internal design, preload or sealing details that vary by configuration. Send us the full designation and we will confirm what each element means for your setup.

Typical installations include milling, grinding and machining center spindles, along with precision tables, measuring equipment, indexing devices and positioning systems that call for high repeatability. In metalworking, automotive and machine tool operations, these bearings are chosen where accuracy and axial load capacity both matter.

When specifying a BST bearing, review the axial load it will carry, the rotational speed and the lubrication conditions. Because these bearings do not tolerate misalignment well, shaft and housing alignment must be precise during mounting. Grease or oil lubrication is possible depending on the application, and sealing is selected according to the working environment. Mounting tolerances and the specified preload should always be respected.

Dimensionally, NTN angular contact thrust ball bearings can interchange with equivalents from other manufacturers that use the same nomenclature, such as SKF, FAG or NSK, as long as the main dimensions and load conditions line up. Internal characteristics can differ from one maker to another, so it is worth verifying the equivalence before substituting. If you only have another brand's code, we can help you locate the NTN equivalent.
