This spindle bearing is a single-row angular contact design with a 25° contact angle, built for precise axial positioning under combined loads. Bore diameter is 60.0 mm, outside diameter 85.0 mm, width 13.0 mm, and net mass 195.7 g. The bearing uses a T cage and is fitted with non-contact lip seals on both sides, keeping friction low while restricting the entry of contaminants. Manufactured to restricted tolerances, the B71912-E-2RSD-T-P4S-UL is matched and supplied in pairs or sets for adjusted mounting arrangements, allowing precise control of internal preload. The defined contact angle makes it suitable for arrangements requiring stable axial guidance and accurate running accuracy, while the integrated seals reduce the need for external protection and support consistent lubrication retention over the operating period.
