Introduction of instruments for testing the reciprocating friction properties of related materials

The main purpose and scope of application of MRS-10A microcomputer-controlled four-ball friction testing machine The machine is mainly in the form of sliding friction, and the bearing capacity
of the lubricant is evaluated under the condition of higher point contact pressure.
Including large no seizure load PB, sintering load PD, comprehensive wear value ZMZ and other three indicators
.
The machine can also do long-term anti-wear test of lubricant, determine the friction coefficient, record the friction force and temperature curve
.
