Product Details

1.Application

This machine mainly uses the form of sliding friction to evaluate the bearing capacity of lubricant under extremely high point contact pressure conditions. There are three indexes including maximum non-clamping load PB, sintering load PD and comprehensive wear value ZMZ. The machine can also do lubricant long - time wear resistance test, measurement of friction coefficient, record friction and temperature curve.
