This spindle bearing carries a 15° contact angle and is manufactured to restricted tolerances for precise axial and radial guidance under high-speed conditions. Bore diameter is 80.0 mm, outside diameter 140.0 mm, width 26.0 mm, and net mass 1.403 kg. The bearing is fitted with a T cage and supplied without sealing, allowing external lubrication and cooling arrangements to be applied as required. Design as B72..-C with P4S accuracy class and UL suffix means the bearing is intended for adjusted mounting in pairs or sets, matched to maintain the specified preload and internal geometry across the set. The restricted tolerances and defined contact angle make it suitable for arrangements requiring accurate axial positioning and minimal radial play at elevated rotational speeds. Absence of sealing requires a separate lubrication and contamination protection system to be provided in the housing design.
