This 4 ball machine adopt sliding friction to evaluate the load-carrying properties of lubricants under extreme high point contact pressure,including Max.non-seizure load PB,weld point PD and universal wear index ZMZ etc.
It can also measure the impact of temperature on lubricants and temperature properties of lubricants.
Evaluate PB,PD,ZMZ,D value of lubricating oil,lubricating grease and cutting fluids..
Control quantity of additives in lubricating oil,lubricating grease and cutting fluids.
The wear scar is measure by camera
User can choose different test method and evaluating index according to different application of lubricants.
It uses high precise Servo system to fulfill stepless speed adjusting.
It’s equipped with special loading stabilizing device
Software can catch wear scar automatically,and measure average value.
It’s equipped with self balancing guidance.
Touch scree controlling,all data is displayed and operated by LCD screen.
It has function of disassembly-free measurement.
It has weight safety protection structure.
