The INA-FAG B71919-E-T-P4S-DFL is a high-precision FAG spindle bearing designed for demanding applications requiring exceptional rigidity and accuracy. This single-row angular contact ball bearing features a 95 mm bore, 130 mm outer diameter, and 18 mm width. It is built to P4S precision class, indicating very high accuracy, and has a 25° contact angle (E design) for optimal axial and radial load support. The T suffix denotes a phenolic resin cage, known for its good high-speed performance and low friction. The DFL arrangement indicates a universal design for paired mounting in a back-to-back (DF) or face-to-face (DB) configuration, with a light preload (L). This bearing is ideal for machine tool spindles and other high-speed, high-precision rotating equipment.
