1. The high-speed bearing the coordination and clearance because high-speed bearing both high precision bearing according to request, and high temperature bearing according to requirements, so in considering the coordination and clearance, want to attend to the following two part:

(1) that the normal temperature high temperature changes to the size of the hardness change;

(2) high speed centrifugal force caused by the force system change and change shape.

In short, at high speed, high temperature conditions, from coordination and clearance to strive to keep on the choice of the precision of the bearing and working performance, this is difficult.

 
In order to guarantee the rolling bearing after installation way little deformation, made of surplus quantity with can't get too big, and high speed centrifugal force under the high temperature and the thermal expansion, or offset surface to the method with the pressure. Or make face with flabby, so a surplus quantity must consider the above two kinds of factors in the premise of prudent to calculation, in room temperature often valid under the speed over surplus quantity for high-speed bearing may is invalid.
