The FAG B7028-C-T-P4S-DTL is a high-performance super precision angular contact ball bearing set, specifically designed for machine tool spindles and other high-speed, high-accuracy applications. This genuine INA-FAG bearing set features a 140 mm bore diameter, 210 mm outer diameter, and a total width of 96 mm. It is configured with a 15° contact angle (C), indicating suitability for high-speed operation with moderate axial loads. The 'T' denotes a phenolic resin cage, known for its excellent high-speed capabilities. 'P4S' signifies a super precision class, ensuring minimal runout and high stiffness. The 'DTL' arrangement indicates a set of three bearings: two in tandem (DT) and one in back-to-back (L) configuration, providing high rigidity and load-carrying capacity in both radial and axial directions with a light preload.
