The FAG B7203CTP4SDFL is a high-precision angular contact spindle bearing designed for demanding applications requiring high rotational accuracy and rigidity. It features a 17mm inner diameter, 40mm outer diameter, and 12mm width. The 'C' designation indicates a 15-degree contact angle, optimized for high-speed operation. Equipped with a 'T' phenolic resin cage, it offers excellent performance in high-speed and high-temperature environments. The 'P4S' tolerance class signifies superior precision, while the 'DFL' universal design allows for flexible duplex mounting arrangements (back-to-back, face-to-face, or tandem) to achieve desired preloads and stiffness.
