KK93100 Four Ball Wear and EP Tester
Four Ball Tester performs both Wear Preventative (WP) and Extreme Pressure (EP) analyses for measuring the wear and frictional properties of lubricants under sliding-on-steel test conditions. Tests are performed in accordance to the latest ASTM and IP published methods. Normal load on the ball assembly and frictional torque are measured through load cells. Wear scars on the steel balls are measured with a graduated-scale microscope and can be recorded with an optional CCD camera. Data is processed and stored utilizing TriboDATA, and advanced data acquisition and processing software package. Test results can be plotted and compared, as well as exported to other programs.
