What are the functions of using automotive water pump bearing materials

     The primary task of the service life analysis of water pump shaft bearings is to find out the primary elements that constitute bearing failures based on a lot of scenery materials, analysis data and failure modes, so as to propose improvement methods, extend the service life of the bearings, and prevent Sudden early failure of the bearing occurred.

     When the shaft diameter is in direct contact with the bearing bush, it prevents sticking and forms the function of gap lubrication. The material elements that affect the compatibility of conflicts are:

    (1) The degree of difficulty of forming an alloy metallurgically in the secondary material.

    (2) The affinity of materials and lubricants.

    (3) The interference factor of the sub-materials in the non-lubricated state.

    (4) The microstructure of the material.

    (5) The thermal conductivity of the material.

    (6) The size of the surface energy of the material and the characteristics of the oxide film.
