This spindle bearing carries a 25° contact angle and ceramic balls, giving low mass at the rolling elements and reduced centrifugal load at high rotational speed. Bore diameter is 35.0 mm, outside diameter 62.0 mm, width 14.0 mm, and net mass 0.16 kg. The bearing uses a T cage and is fitted with 2RSD lip seals on both sides, running non-contact for low friction. It is supplied adjusted, in pairs or sets, to P4S restricted tolerances. The tight P4S tolerance class supports precise shaft guidance and low running error, while the paired arrangement allows a defined preload to be set for stiffness under axial and combined loading. The non-contact lip seals keep out contamination without adding frictional torque, which suits the high-speed operating range this design targets. Grease or oil lubrication can be applied according to the mounting arrangement and preload selected for the pair or set.
