introduction：bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The clearance refers to when the bearing is not installed in the shaft or bearing box，Fasten one of its inner or outer rings，Then there is the amount of movement when the unfixed party makes a radial or axial move。therefore，The measured value obtained is better than the true clearance（This is called theoretical gap）big，That is to increase the measurement load generated

introduction：Air bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]：Air bearings use high pressure gas to suspend the journal in the bearing ring，Plain bearings using air as lubricant，Completely eliminate the friction between the solids and the resulting heat。Air is less viscous than oil，High temperature resistance，pollution-free，It can therefore be used in high-speed machines、Instrumentation and radioactivity
