The INA-FAG B7004-E-T-P4S-DFL is a high-precision angular contact ball bearing, specifically designed for demanding machine tool spindle applications. This genuine FAG bearing features a 25° contact angle (E), a solid window cage made of textile laminate (T), and a P4S precision class, indicating very high running accuracy and speed capability. The 'DFL' designation indicates a universally matchable pair of bearings for duplex arrangement, typically used in a back-to-front (DF) configuration with light preload (L). With a bore diameter of 20 mm, an outer diameter of 47 mm, and a width of 12 mm, this bearing ensures optimal performance and rigidity in high-speed rotating machinery.
