The use conditions and the surrounding conditions of the bearings

Correct definitions on the application position in the mechanical device and the use conditions of choosing the proper bearing.For this prupose,the following figures and data are required.

(1)The functions and structure of the mechanical device;

(2)The application position;

(3)Loads(how big and in which directions);

(4)Rotating speed;

(5)Vibration and shock;

(6)Temperature of the bearing(surrounding temperature and rises);

(7)Surrounding ambience(corrosion,cleanness,lubrication).
