Precise angular contact positioning at high rotational speeds is achieved through a 25° contact angle combined with ceramic balls, reducing centrifugal load and heat generation at the rolling contact. This spindle bearing, bore 110.0 mm, outside diameter 170.0 mm, width 28.0 mm, net mass 2.05 kg, features a T cage and non-contact lip seals on both sides (2RSD), keeping frictional torque low while limiting contaminant ingress. Restricted tolerances (P4S) and matched adjustment support consistent running accuracy when mounted in pairs or sets. Suitable for arrangements requiring universal matching (UL) and defined preload without additional selective fitting, this design allows mounting in back-to-back, face-to-face, or tandem sets depending on stiffness and load direction requirements. The non-contact seals reduce heat buildup at elevated speeds compared to rubbing seals, while the restricted P4S tolerance class ensures the dimensional consistency needed for precise shaft positioning under combined radial and axial loads.
