Used in CNC machining centers and precision machine tools, the Nachi 25TAU07F-2NSE/GM is an axial angular contact ball screw support bearing with a 25 mm bore, 75 mm outer diameter, and 28 mm width. It carries the P4N precision grade designation, indicating a high-accuracy tolerance class suited for demanding machine tool applications. The suffix 2NSE denotes double rubber seals for contamination protection, and the GM designation reflects grease-filled, maintenance-friendly construction. Additional markings on the box include P4N, JJ, and MTSBM, consistent with Nachi's standard suffix coding for preload, internal geometry, and seal type. The date code 170809 is printed on the original Nachi Precision Bearings box. A DMG Mori label on the packaging identifies part number SBF2689840B and references dimensions of 25 x 75 x 28 mm, confirming fitment as a support bearing in DMG Mori machine tool assemblies. Nachi is a vertically integrated Japanese manufacturer that produces the steel used in its own bearings, a characteristic that distinguishes its precision product line in the machine tool and industrial automation markets. The 25TAU07F series is part of Nachi's TAU cartridge-type ball screw support bearing lineup, designed to simplify installation and eliminate the need for manual preload adjustment.
