introduction：INA Bearing type The choice is determined by the direction of the load acting on the bearing，The choice of the right combination of contact surfaces mainly depends on the mode of load operation。The following describes several ways of loading： 1、Radial load When the load is pure radial load or mainly radial load，Radial spherical bearings should be selected。 Except radial load，This type ofINAThe bearing can also withstand a certain axial load。 2、Axial load When the load is pure axial load or mainly axial load，Spherical thrust bearings should be selected。 In addition to the axial load，This type ofINAThe bearing can also bear a certain radial load。 3、Combined load When the load consists of radial and axial components of almost equal magnitude，Angular contact ball bearings should be selected。Such bearings can only withstand axial loads from one direction，Usually its the second oneINAAdjustment of bearing，Bear the axial load from the opposite direction。 4、Directional load For example, the direct

introduction：second、 INAThe metallurgical quality of bearing materials used to be the main factor affecting the early failure of rolling bearings。With metallurgical technology（For example, vacuum degassing of bearing steel）The progress of，The quality of raw materials has improved。Raw material quality factors inINAThe proportion of bearing failure analysis has decreased significantly，But it is still one of the main influencing factors of bearing failure。 third、 Whether the material is chosen properly remainsINAFactors that must be considered in bearing failure analysis。INAThe main task of bearing failure analysis，Based on a lot of background material、Analyze data and failure patterns，Find out the main factors that cause bearing failure，In order to put forward targeted improvement measures，Extend the service life of bearings，Avoid sudden early bearing failure。Installation conditions are one of the first factors in useINABearings are often set due to improper installationINAThe stress state of each part of th
