introduction： entranceIKOThe service life and reliability of bearings are largely related to 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 smelting quality of steel is closely related。Due to the characteristics of bearing steel，The requirements for smelting quality are much stricter than those for general industrial steel，Like the chemical composition of steel、purity、Organization and balance

introduction： The sealing mechanism of oil seals involves two factors，One is the sealing of the cavity，Mainly the outer edge of the oil seal（Static unit）Positioning in the cavity；The second is the dynamic sealing of the sealing lip in contact with the surface of the rotating shaft，This is the most important function of the oil seal。 The outer edge of the oil seal is to ensure the static sealing of the oil seal in the cavity and the stable positioning in the hole，And easy to assemble。Generally rubber material covered with metal skeleton，The reliable static sealing capability of rubber elastomer is combined with the advantages of metal skeleton support positioning。The outer edge of the oil seal is designed with chamfer，Facilitate assembly。Another oil seal is arranged on the outer edge
