Bearing in high speed rotating speed, especially close to or more than size recorded in the list of limit rotational speed, the main should pay attention to the following items:
 
(1) using precision bearing;
 
(2) analysis of internal bearing clearance (consider from the internal temperature of the bearing clearance decrease);
 
(3) analysis of the material maintains a type (for high speed rotating, suitable to adopt copper alloy or phenolic resin system maintains a cut. In addition also has used in high speed rotating synthetic resin molding maintains a);
 
(4) analysis lubrication method (use of suitable for high-speed rotating circulation lubrication, jet lubrication, oil mist lubrication and lubrication oil and gas lubricating way)
