This spindle bearing carries a 25° contact angle and is manufactured to restricted tolerances for precision applications requiring accurate axial and radial location under combined loading. Bore diameter is 80.0 mm, outside diameter 125.0 mm, width 22.0 mm, and net mass 0.84 kg. The bearing is supplied adjusted, in pairs or sets, allowing correct preload to be established without additional matching on assembly. Cage design is designated T. The bearing is unsealed, so lubrication and contamination protection must be provided externally by the housing design. The P4S accuracy class supports high running accuracy and stable stiffness at elevated speeds, while the paired/set configuration and defined contact angle allow controlled axial rigidity when mounted back-to-back or face-to-face. The UL designation indicates suitability for oil lubrication.
