» Bearings for high speed operations

Sep 15, 1994· With angular contact ball bearings running at high speeds the increase of stiffness will be greater due to the improved dynamic behaviour of the balls, i.e. the smaller change in contact angles. The smaller deformation in the contact zone of the ceramic rolling element and the steel ring also means that the contact area will be smaller.
