The NTN BST series angular contact thrust ball bearing is a precision component designed to support axial loads in one direction, with high rigidity and rotation capability. It is used in machine tool spindles, rotary tables and other systems requiring accuracy and repeatability. MR Accesorios Industriales sells this series with the technical backing of more than 80 years in the Argentine industrial market.

The BST series designation consists of the letters BST followed by a number indicating the shaft diameter, a second number indicating the outer diameter, a hyphen and a suffix that may include BLXL. For example, BST40X72-1BLXL corresponds to a bearing for a 40 mm shaft and 72 mm outer diameter. The BLXL suffix identifies an execution with preload and lubrication for high speed, aimed at spindle applications. Each variant in the series maintains the same naming logic, which makes selection by dimensions easier.

These bearings are used in milling machine, grinding machine, boring machine and machining center spindles, where axial loads are predominant. They are also used in measuring machine tables, precision drill heads and automation equipment that demands exact positioning. In Argentine industry, they are common in the metalworking, automotive and capital goods sectors, especially in production and maintenance machine tools.

To select the right bearing, take into account the direction of the axial load, the rotation speed and the rigidity required by the spindle. The BST series allows preload mounting, which reduces clearance and improves rotation accuracy. It is essential to verify alignment between the shaft and the housing, as well as proper lubrication, which may be grease or oil depending on the application. Sealing or protective plates must be chosen according to the working environment to prevent contamination by particles or coolant.

NTN BST series angular contact thrust ball bearings may be found with equivalent designations from other manufacturers, although they do not always match exactly in dimensions or load capacity. When looking for a replacement, it is essential to compare the mounting dimensions, the type of execution and the service conditions. If you have another brand's code or an unidentified part, we can guide you to find the option compatible with your equipment.
