The FAG B7020-C-T-P4S-K5-UL is a high-precision single-row angular contact ball bearing designed for demanding spindle applications. Manufactured by FAG (part of the Schaeffler Group), this bearing features a 15° contact angle (C) for high speed and rigidity, a textile laminate cage (T), and P4S precision class (equivalent to ISO Class 4 or ABEC 7 for dimensional accuracy and running precision). The 'K5' indicates a specific bore tolerance, and 'UL' signifies a universal arrangement for paired mounting with light preload, allowing for flexible configuration in sets. Its robust design ensures excellent performance in machine tool spindles and other high-speed, high-precision rotating equipment.
