This precision angular contact bearing supports spindle shafts with a 25° contact angle, providing defined axial and radial positioning under combined loads. Bore diameter is 65.0 mm, outside diameter 90.0 mm, width 13.0 mm, and net mass 199.41 g. The bearing uses a T-type cage and features non-contact lip seals on both sides, keeping friction and heat generation low while protecting the raceways from contamination. Manufactured to restricted tolerances, this B71913-E-2RSD-T-P4S-UL bearing is matched and supplied in pairs or sets for adjusted mounting arrangements, allowing precise control of internal preload. The tight tolerance class and 25° contact angle make it suitable for applications requiring high running accuracy and stiffness under combined axial and radial loading, while the integrated seals allow operation without external sealing arrangements.
