The MRS-10D four ball friction and wear testing machine is specifically designed to evaluate the bearing capacity of lubricants, including maximum non bite load PB, sintering load PD, comprehensive wear value ZMZ, and other indicators. Long term anti-wear tests of lubricants can also be conducted, measuring the friction coefficient and recording the friction and temperature curves.
