This spindle bearing is a single-row angular contact type with a 15° contact angle, designed for precise axial and radial location under combined loading. Bore diameter is 55.0 mm, outside diameter 90.0 mm, width 18.0 mm, and net mass 371.71 g. It features a T cage and non-contact lip seals on both sides, protecting the internals while keeping friction low. The B7011-C-2RSD-T-P4S-UL is supplied adjusted, in pairs or sets, allowing mounting in back-to-back, face-to-face or tandem arrangements without additional matching on site. Restricted tolerances (P4S) and the UL designation support the accuracy and low run-out needed for high-speed rotation, while the sealed design keeps the bearing suitable for grease lubrication without external contamination.
