Used in CNC machining centers and precision machine tools, the Nachi 25TAU07F-2NSE/GM is an axial angular contact ball screw support bearing with an inner diameter of 25 mm, outer diameter of 75 mm, and a width of 28 mm. Manufactured to P4N precision grade, this bearing is engineered for applications requiring high axial rigidity and accurate positioning, such as ball screw shaft support in DMG Mori and other CNC machine tool platforms. The MPN 25TAU07F-2NSE/GM designates double-sealed construction with GM grease fill and a ground universal duplex-compatible outer ring. The TAU series design incorporates a contact seal configuration that protects internal components from contamination while retaining lubricant under operating conditions. This bearing is part of Nachi's precision TAU line, which is specifically developed for ball screw support applications where preload consistency and low torque variation are critical. The label on this item also carries DMG Mori internal reference number SBF2689840B and machine designation MC1530, confirming its use as a factory-sourced support bearing for that platform. Nachi is a Japanese precision bearing manufacturer with a long-standing presence in the CNC and machine tool industry.
