The FAG B7203-E-T-P4S-DBL is a high-precision angular contact ball bearing from INA-FAG (Schaeffler), specifically designed for demanding applications such as machine tool spindles. This single bearing features a 17mm bore, 40mm outer diameter, and 12mm width. The 'E' designation indicates an optimized internal design, while 'T' signifies a phenolic resin cage for high-speed capability. With a P4S precision class (better than ISO P4) and a 25° contact angle, it offers exceptional running accuracy and rigidity. It is typically supplied as a matched component for duplex mounting (DBL) with light preload, ensuring optimal performance in high-speed, high-accuracy machinery.
