This spindle bearing carries a 25° contact angle and an internal design matched for adjusted mounting in pairs or sets, allowing precise axial positioning under combined loads. Bore diameter is 75.0 mm, outside diameter 105.0 mm, width 16.0 mm, and net mass 339.53 g. The cage is made in T version, and the bearing is supplied without sealing. Restricted tolerances corresponding to P4S accuracy class make this bearing suitable for applications requiring tight running accuracy and low radial and axial runout. Since it is intended for paired or set arrangement, correct orientation and matched preload during mounting are required to achieve the specified contact angle and stiffness. The absence of sealing means external lubrication and contamination protection must be provided by the housing design, and grease or oil lubrication should be selected according to the operating speed and preload conditions.
