The FAG B71916-E-T-P4S-DBL is a high-precision angular contact ball bearing, part of the Schaeffler Group, specifically designed for demanding machine tool spindle applications. This hybrid bearing features ceramic balls (indicated by the 'T' suffix) for enhanced performance, higher speed capabilities, and reduced friction and heat generation. It boasts an 80 mm bore diameter, 110 mm outer diameter, and a 16 mm width, with a 25° contact angle (denoted by the 'E' suffix). The P4S accuracy class ensures exceptional running precision and stiffness, crucial for high-speed and high-accuracy operations. The 'DBL' designation signifies a duplex arrangement (back-to-back) with a light preload, optimized for rigidity and speed in critical industrial machinery.
