MRS Series Four Ball Wear Test Machine

Main functions
This machine is used to evaluate carrying capacity of lubricant under high contact pressure by sliding friction, including the largest non-card bite load Pb, sintering load Pd and the composite wear value ZMZ; it can also be used for a long time wear tests, determination of friction and the frictional coefficient calculation. Equipped with special annex, it can also be used to do end-wear test and simulation test for materials.
