When the shaft is moved with a crowbar to make the shaft in two extreme positions, the difference between the dial indicator readings is the axial clearance of the bearing. The size of the clearance (called the working clearance) during operation has an impact on Wholesale roller bearing manufacturers the bearing's rolling fatigue life, temperature rise, noise, vibration and other properties. 2. The matching of the outer ring of the bearing and the housing hole.

When the rotation accuracy is high or the axial displacement needs to be strictly limited, a small clearance group should be used. The operation method is the same as the method for checking radial clearance with a plug, but the axial clearance should be c=λ/(2sinβ) where c——axial clearance, mm; λ——thickness of feeler gauge, mm; β——bearing cone angle, (°). Note: The reduction in radial clearance is related to the actual effective interference of the matching parts, the matching shaft diameter, and the wall thickness of the housing hole.

However, the force applied to the crowbar cannot be too large, otherwise the shell will be elastically deformed, even if the deformation is small, it will affect the accuracy of the measured axial clearance. The bearing clearance standard is not regulated by the country and depends on the use situation: it is still a very complicated problem, which is briefly described as follows: A. This method is used when the shaft end is exposed.

Bearing clearance is also called bearing clearance. When the shaft end is closed or cannot be checked with your fingers for other reasons, you can check whether the shaft rotates flexibly. Check with a dial indicator.. A tighter fit is adopted, the temperature difference between the inner and outer rings is large, and the friction torque needs to be reduced. According to the direction of movement, it can be divided into radial clearance and axial clearance
