The SKF 7407 BMG is a high-precision, single-row angular contact ball bearing engineered for demanding industrial environments requiring superior stiffness and speed. Featuring a 40-degree contact angle (indicated by the 'B' designation), this design is optimized for handling high combined radial and axial loads, with the axial load acting in one direction. The precise internal geometry and optimized ball set ensure reduced friction, minimal heat generation, and excellent guiding characteristics necessary for accuracy. With bore dimensions of 35 mm, an outer diameter of 72 mm, and a width of 17 mm, the 7407 BMG is a standardized solution built for reliable integration into existing machinery.
Ideal for critical applications such as machine tool spindles, gearboxes, high-speed pumps, and industrial compressors, the 7407 BMG delivers unparalleled operational reliability and extended service life. Utilizing genuine SKF materials and manufacturing tolerances, this bearing ensures maximum precision and stiffness under continuous operation, minimizing runout and vibration. This translates directly into higher component quality, reduced maintenance downtime, and optimized productivity. For systems requiring bi-directional axial support or higher stiffness, these bearings can be easily mounted in duplex arrangements (DB, DF, DT configurations) to meet specific load and deflection requirements.
