The HFH B71912-C-T-P4A-UL is a high-precision angular contact ball bearing designed for demanding machine tool spindle applications. It features a 60 mm bore diameter, a 95 mm outer diameter, and a 18 mm width. This bearing is characterized by its P4A precision class, indicating very high accuracy suitable for critical rotating components. The 'C' designation typically refers to a 15-degree contact angle, and 'T' often denotes a phenolic resin cage, which provides good high-speed performance and low friction. The 'UL' suffix indicates a universal matching capability for duplex arrangements.
