The FAG B71910-C-T-P4A-DUL is a high-precision angular contact ball bearing specifically engineered for demanding machine tool spindle applications. Featuring a 50 mm bore, 80 mm outer diameter, and 16 mm width, this bearing is designed for high rotational speeds and exceptional rigidity. It has a 15° contact angle (C), P4A tolerance class for superior accuracy, and a light preload (T) for optimal performance. The DUL designation indicates a universal design, allowing for paired mounting in back-to-back, face-to-face, or tandem arrangements with a light axial preload. This FAG bearing ensures reliable operation and precision in critical machinery.
