MR-S10G lever type four ball friction testing machine
The MR-S10G lever type four-ball friction and wear tester is based on sliding friction. It is mainly used to evaluate the bearing capacity of lubricants under the conditions of extremely high point contact pressure, including maximum no-bite load P B and sintering load P D . The comprehensive wear value ZMZ and other three indicators, in practical applications, different evaluation indicators can be selected according to the various uses of the lubricant.
The test oil tank has an ambient temperature of up to 250 °C, and can be pre-selected for time, friction, temperature, etc., and the friction coefficient of the friction coupler can also be determined.
