introduction:IKOCylindrical roller bearings[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 fit with the shaft is generally a transitional fit,The fit between the seat ring and the bearing seat hole is generally a clearance fit,The central shaft ring of the bidirectional bearing shall be fixed on the shaft,To prevent rolling relative to the axis。If its upside down,Not only the bearings are not working properly,And each mating surface will suffer severe wear。box

introduction: During the assembly process, Bearings can also be checked[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。]Quality of material, Thus identify the quality of the bearing。When the bearing inner ring is mounted on the shaft, Under normal operating conditions, If the bearing material is not qualified, Due to the inner ring stress deformation, It will cause the deformation of the support or the change of the clearance
