The INA-FAG B71900-E-T-P4S-DBL is a high-performance super precision angular contact ball bearing set, specifically designed for demanding spindle applications requiring high rigidity and accuracy. This duplex set features a back-to-back (DBL) arrangement with a light preload, ensuring optimal performance. Each bearing in the set has a bore diameter of 10 mm, an outer diameter of 22 mm, and a nominal width of 6 mm, resulting in a total set width of 12 mm. It features a 25° contact angle ('E' designation) for high axial and radial load capacity, and a PEEK cage ('T' designation) for high-speed capability and reduced friction. The P4S precision class ensures extremely tight tolerances and superior running accuracy, making it ideal for machine tool spindles and other high-speed, high-precision rotating equipment.
