The HFH B7216CTP4SUL is a high-precision single row angular contact ball bearing, specifically designed as a spindle bearing for demanding applications. Featuring an 80 mm bore, 140 mm outer diameter, and 26 mm width, this bearing is engineered for high speed and high rigidity. It has a 15-degree contact angle ('C'), a phenolic resin cage ('T') for reduced friction and heat generation, and is manufactured to P4S (ultra-precision) standards. The 'UL' designation indicates a universally matched pair with light preload, ensuring optimal performance in machine tool spindles and other precision machinery.
