The FAG B7215-E-T-P4S-DFL is a high-performance super precision angular contact ball bearing pair, specifically designed for spindle applications requiring extreme rigidity and accuracy. This duplex bearing set features a 25-degree contact angle (E) and is arranged face-to-face (DF) with a light preload (L) to ensure optimal running characteristics. Manufactured to P4S precision class, it offers superior running accuracy and high-speed capabilities. The bearing has a bore diameter of 75 mm, an outer diameter of 130 mm, and an individual width of 25 mm, resulting in a total width of 50 mm for the mounted pair. It incorporates a robust textile laminate (phenolic resin) cage (T) for high-speed operation.
