The FAG B71919-C-T-P4A-DUL is a high-precision angular contact ball bearing designed for demanding spindle applications. Featuring a 15° contact angle (C), it is engineered for high speed and rigidity. The bearing incorporates a phenolic resin cage (T) for excellent performance at high speeds and temperatures. It meets P4A precision standards (equivalent to ABEC 7), ensuring exceptional running accuracy. The 'DU' designation indicates that it is universally ground for paired mounting, allowing for various arrangements (tandem, back-to-back, face-to-face), and 'L' signifies a light preload for optimal stiffness and reduced vibration in high-speed operations. This bearing is suitable for machine tool spindles and other precision rotating equipment.
