Relevant parts of requirements of the high speed bearing host

Rotating system of high speed bearings  require  precision dynamic balancing.Installation bearing part of shaft and hole  is higher than the general requirements for the dimensional accuracy and the position accuracy .

  LYHY bearings, especially the verticality of coaxiality and shoulder block seat hole or shaft neck, and in consideration of these problems, we must  pay attention to the high speed factors bearing in operation and high temperature factor.

  Shaft bearing system requires high rigidity,  as far as possible the light quality. In order to overcome this contradiction,we can  take measures  to improve the supporting stiffness ,such as reducing the surface roughness and improving the surface strengthening  , or using  hollow shaft to reduce the quality of the system etc.
