Addition and subtraction on the installation clearance dimensions due to internal temperature differences of FAG bearings clearance after variation is called "effective clearance".
FAG bearings fitted with a mechanical bear loads placed on the clearance, namely the effective clearance plus the FAG bearing load of elastic deformation of so called "working clearance".　
When the operational clearance is slightly negative, FAG bearing fatigue life the longest but with negative clearance increases fatigue life with decreased significantly. Therefore, when choosing a FAG bearing clearance, general operational clearance is zero or slightly positive.
In addition, to increase the rigidity of FAG bearings or to when noise reduction, operational clearance further to draw the negative, and when the bearing temperature rises dramatically, operational clearance to further take positive values, and so on, must also be in accordance with the conditions of use for specific analysis.
