Introduction to bearing clearance
The bearing clearance is the gap between the bearing rolling element and the inner and outer ring housing of the bearing. The so-called bearing clearance refers to the amount of movement when the bearing is fixed to one of the inner ring or the outer ring when it is not mounted on the shaft or the bearing housing, and then the radial or axial movement of the bearing clearance is not fixed. . According to the direction of movement, it can be divided into radial clearance and axial clearance. The size of the running clearance (called the working clearance) affects the rolling fatigue life, temperature rise, noise, vibration and other properties of the bearing.
