The FAG B7011-E-T-P4S-DBL is a genuine Schaeffler high-precision angular contact ball bearing set, specifically engineered for demanding machine tool spindle applications. This matched set features a 25° contact angle (E design) and a robust textile laminate cage (T) for optimal performance at very high speeds. With a bore diameter of 55 mm, an outer diameter of 90 mm, and a total width of 36 mm (for the DBL back-to-back arrangement), it delivers exceptional rigidity and accuracy. The P4S precision class ensures very tight tolerances and superior running accuracy, making it an ideal component for machinery requiring high rotational speeds and precise positioning.
