Rolling bearings are manufactured with regular clearance according to the contract. This clearance is usually called the original clearance. When the bearing is installed on the main machine, the bearing clearance value is reduced because of the interference cooperation of a certain ferrule. The clearance formed by the device is called the device clearance; through the operation, the temperature of the bearing parts rises, the volume changes, and the temperature rises due to the increase of the temperature of the shaft or the shell of the bearing. Incurring the change of the bearing clearance again, the play clearance for this operation is called the working clearance. The working clearance is usually smaller than the device clearance; sometimes the clearance value will be different from the assembly and device methods. Increase.
