1. Product introduction
The MR-S10 series four-ball friction tester is in the form of sliding friction. It is mainly used to evaluate the bearing capacity of lubricants under extremely high point contact pressure conditions. Including the maximum non-seizure load Pb, sintering load Pd, comprehensive wear value ZMZ and other three indicators, in actual applications, different evaluation indicators can be selected according to various uses of the lubricant.
