Name：MRS-10A microcomputer control four ball friction testing machine     Model：MRS-10A Category：friction testing machine | material tensile testing machine Price：negotiable Place of origin：shandong jinan

　　Purpose and scope of application:

The MRS-10A microcomputer control four ball friction testing machine is mainly in the form of sliding friction, in the high point of contact pressure conditions to assess the carrying capacity of lubricants. Including the maximum no clamping load PB, sintering load PD, the comprehensive wear value of ZMZ and other three indicators. Friction and wear testing machine MRS-10A lubricant can be done long-term wear resistant test and determination of the coefficient of friction and record of friction force and temperature curve. With high precision measuring device, measuring friction vice grinding spot size and friction wear spot computer screen shows that measured and recorded.
