Description
This spindle bearing carries a 15° contact angle and is designed for adjusted mounting in pairs or sets, allowing precise axial positioning under combined loads. Bore diameter is 55.0 mm, outside diameter 80.0 mm, width 13.0 mm, and net mass amounts to 174.13 g. The bearing is fitted with a T cage and supplied without sealing, built to restricted tolerances (P4S) for high running accuracy. The C-type design combined with restricted tolerances makes this bearing suitable for arrangements requiring tight radial and axial guidance at elevated rotational speeds, where matched sets ensure even load distribution across the pair. The absence of sealing means external lubrication and contamination control must be provided by the housing design, and grease or oil lubrication should be selected according to the operating speed and preload requirements of the specific spindle arrangement.
