一、 Main purpose
The microcomputer controlled four ball friction and wear testing machine mainly evaluates the bearing capacity of lubricants in the form of sliding friction under extremely high point contact pressure conditions. Including three indicators: maximum no bite load PB, sintering load PD, and comprehensive wear value ZMZ. This machine can also perform long-term wear resistance tests on lubricants and measure the friction coefficient.
