When we choose the bearing, we often encounter C3 bearing, what are the characteristics of C3 bearing belt
C3 is the clearance of the bearing, that is, its axial clearance and radial clearance
The absence of C3 is the standard clearance.
The C3 clearance is larger than the standard clearance
The so-called bearing clearance, that is, when the bearing is not installed in the shaft or the bearing box, the inner ring or the outer ring of the bearing is fixed, and then the non-fixed one does radial or axial movement.According to the moving direction, it can be divided into radial clearance and axial clearance.
The running clearance (called working clearance) has an effect on the rolling fatigue life, temperature rise, noise and vibration of the bearing.
When measuring the clearance of a bearing, a specified measuring load is generally applied to the bearing in order to obtain a stable measuring value.
