  » Bearings for high speed operations

   · 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, 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. Under the same external load, stresses will be higher and ...

  The grinding balls then cross the bowl at high speed and further grind the sample material by impact against the opposite bowl wall. In addition, impact between the balls themselves on the sample material adds to the size reduction process. Due to the enormous rotational speed of the main disk – up to 800 rpm – the PULVERISETTE 7 classic line reaches a centrifugal acceleration of up to 50 g.
