Overview

Four ball machine (four ball friction and wear testing machine)

Product Details

MRS-10WMicrocomputer controlled four ball friction and wear testing machine

Brief introduction
The microcomputer controlled four ball friction and wear testing machine is designed and manufactured according to GB/T2611-2007 General Technical Requirements for Testing Machines, GB/T12583-98 Lubricant Extreme Pressure Performance Determination Method (Four Ball Machine Method), GB3142-82 Lubricant Load Capacity Determination Method (Four Ball Machine Method), SH/T0189-92 Lubricant Anti Wear Performance Determination Method (Four Ball Machine Method), SH/T0202-92 Lubricant Extreme Pressure Performance Determination Method (Four Ball Machine Method), SH/T0204-92 Lubricant Anti Wear Performance Determination Method (Four Ball Machine Method), ASTM D2625, ASTM D5183, ASTM D2266, ASTM D4172 and other standards. This machine can perform long-term wear resistance tests on lubricants, measure friction coefficients, and record friction and temperature curves The machine is equipped with a high-precision measuring device that can measure the size of friction pair wear spots, or achieve computer screen display, measurement, and recording of friction pair wear spots.
The four ball friction testing machine is mainly used to evaluate the bearing capacity of lubricants in the form of sliding friction under extremely high point contact pressure conditions. Including three indicators: maximum non card bite load Pb, sintering load Pd, and comprehensive wear value ZMZ, different evaluation indicators can be selected according to the various uses of lubricants in practical applications.
