The FAG B71902-C-T-P4A-UM is a high-precision single-row angular contact ball bearing designed for demanding spindle applications. Featuring a 15° contact angle ('C'), this bearing is optimized for high speeds and radial-axial loads. It adheres to P4A tolerance class (equivalent to ABEC 7), ensuring exceptional running accuracy and stiffness. The 'T' designation indicates a fiber-reinforced phenolic resin cage, suitable for high-speed operation. The 'UM' suffix signifies universal matching, allowing for arbitrary arrangement of single bearings or sets without special selection, providing flexibility in assembly. This bearing is ideal for machine tool spindles and other precision rotating equipment.
