Description
This spindle bearing carries a 15° contact angle and is designed for precise axial and radial positioning under combined loads. Bore diameter is 40.0 mm, outside diameter 62.0 mm, width 12.0 mm, with a net mass of 107.81 g. The bearing features a T cage and non-contact lip seals fitted on both sides, keeping friction low while restricting the ingress of contaminants. Supplied as B71908-C-2RSD-T-P4S-UL, it is matched and intended for mounting in pairs or sets, allowing correct preload to be achieved for adjusted arrangements. The P4S accuracy class and restricted tolerances support high running accuracy and stable behavior at elevated speeds, while the integrated seals reduce the need for external sealing and permit operation with a grease fill sized for the internal clearance of the set.
