The FAG B7204CTP4AUM is a high-precision single-row angular contact ball bearing, specifically designed as a spindle bearing for demanding applications like machine tool spindles. It features a 20 mm bore, 47 mm outer diameter, and 14 mm width. The 'C' suffix denotes a 15° contact angle, while 'T' indicates a textile laminate cage, optimized for high-speed operation. The 'P4A' precision class ensures exceptional running accuracy and rigidity. 'UM' signifies universal matching, allowing for flexible mounting in various configurations (tandem, back-to-back, face-to-face) without requiring shims, making it ideal for creating bearing sets.
