[0002] Bearing clearance is the gap between the rolling element and the outer ring of the bearing. The so-called bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing box, one of the inner ring or outer ring is fixed, and then the bearing clearance is moved radially or axially.
