The INA-FAG B71930-C-T-P4S-DUL is a high-precision angular contact ball bearing designed for demanding spindle applications. This genuine FAG bearing features a 150 mm bore diameter, 210 mm outer diameter, and a 28 mm width. It is equipped with ceramic balls (suffix T) for enhanced performance, higher speed capabilities, and reduced friction. The 'C' contact angle indicates a 15-degree nominal contact angle, suitable for high-speed applications. With P4S precision class, it meets stringent requirements for accuracy and rigidity in machine tool spindles and other high-speed rotating equipment. The 'DUL' designation indicates a universal design for paired mounting.
