Hot Automatic Four Ball Tester (including friction coefficient)


The automatic four ball tester is quipped with microscope image measurement system software; it can measure constant grinding, maximum non-jamming load PB, sintering load PD, comprehensive wear value ZMZ, automatic calculation of ZMZ and other values, and print the test results into a standard table, and the test results are easy to observe. It can also measure the friction coefficient.

The purpose of measurement of Extreme-Pressure properties of a lubricating grease:

To determine the load carrying capabilities of a lubricating grease under high load applications like bearings.

The purpose of measurement of Wear scar Properties and Coefficient of Friction of a lubricating grease:

To determine the wear preventive characteristics of a lubricant. In the 4-Ball Wear test, a steel ball is rotated against three lubricated stationary steel balls under a specified load, speed, temperature and time.
