The FAG B7009ETP4SDBL is a high-performance super precision angular contact ball bearing, specifically designed for demanding applications requiring exceptional rotational accuracy and high rigidity, such as machine tool spindles. This genuine FAG bearing features a 45 mm bore, 68 mm outer diameter, and 12 mm width. It incorporates a 25-degree contact angle (E) for enhanced axial and radial load capacity, and a textile laminate cage (T) for high-speed operation. The P4S precision class signifies superior manufacturing tolerances. Configured as a DBL (Duplex, Back-to-Back, Light preload) set, it is pre-arranged for optimal stiffness and performance.
