The FAG B7208-E-T-P4S-DFL is a high-precision angular contact ball bearing, specifically engineered for demanding machine tool spindle applications. This part number designates a matched pair of bearings (DFL arrangement) featuring a 25° contact angle (E design) for superior axial and radial rigidity, and a textile-reinforced phenolic resin cage (T) enabling high-speed operation. With a bore diameter of 40 mm, an outer diameter of 80 mm, and a single bearing width of 18 mm, these bearings adhere to the P4S precision class (equivalent to ISO Class 2), ensuring exceptional running accuracy and performance. The DFL configuration signifies a duplex arrangement, mounted face-to-face with light preload, optimized for rigidity and precision in critical machinery.
