The NSK TAC series angular contact thrust ball bearing is a precision component designed to withstand axial loads combined with high rotational speeds. It is used in machine tool spindles and other systems where axial rigidity and rotational accuracy are required. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and advises you on selecting the right part number for your application.

The TAC series designation is read from its numbers and letters. For example, 140TAC03DM indicates a 140 mm bore, followed by the letters TAC that identify the angular contact series, then 03 which defines the contact angle, and the DM suffix which indicates a special execution, usually with preload and matched mounting pairs. The part numbers 160TAC03DM and 180TAC03DM follow the same logic for 160 and 180 mm bores. Learn what each part means so you can choose the right bearing.

These bearings are used in main spindles of milling machines, boring machines, grinding machines and machining centers, where axial loads are predominant and high rotational accuracy is required. They also appear in rotary tables, drill heads and measuring equipment. In Argentine industry, they are common in the metalworking, automotive and machine tool sectors, where reliability and repeatability are critical to production.

To select the right bearing, take into account the axial load it must withstand, the maximum operating speed and the rigidity required by the spindle. Mounting must be done with suitable tools to avoid damaging the raceways, and it is essential to verify alignment between the shaft and the housing. Lubrication, whether with grease or oil, must be the one specified for the application, and sealing will depend on the working environment. Preload, when applicable, is defined according to the spindle manufacturer.

NSK TAC series bearings may be found with equivalent designations from other manufacturers, although there is no universal standardization for this type of precision bearing. When looking for a replacement, it is important to compare the main dimensions, the contact angle and the preload conditions.
