The Four-Ball Tribometer is a high-precision laboratory instrument designed to evaluate the wear resistance, extreme-pressure (EP) performance, and friction characteristics of lubricating greases and oils. You can control load, speed, and temperature with high accuracy through pneumatic low/high load cylinders and an air-bearing torque measurement system. The instrument features a touch-screen PC interface for data acquisition and supports optional modules for rolling four-ball tests, shear stability evaluation, and high-resolution wear scar measurement.
Application
You can use this tribometer for a wide range of laboratory tests, including:
(1) Evaluating wear resistance of lubricating greases and oils.
(2) Assessing extreme-pressure (EP) performance of lubricants.
(3) Measuring friction coefficients for research and quality control.
(4) Performing rolling contact fatigue tests with the optional rolling four-ball module.
(5) Conducting shear stability tests on polymer-containing lubricants (optional KRL module).
(6) Measuring and analyzing wear scars using an optional high-resolution digital microscope.
(7) Laboratory testing of automotive, industrial, and hydraulic lubricants.
(8) Quality control of lubricants in research and production labs.
Standards
You can perform tests in compliance with international standards, including:
(1) ASTM D2266 – Wear performance of lubricating grease
(2) ASTM D4172 – Wear performance of lubricating oil
(3) ASTM D2596 – Extreme-pressure performance of lubricating grease
(4) ASTM D2783 – Extreme-pressure performance of lubricating oil
(5) ASTM D5183 – Friction coefficient of lubricants (four-ball method)
(6) IP 239 – Lubricant extreme-pressure and wear tests
(7) DIN 51350/1-5 – Four-ball testing of lubricants
(8) ISO/CD 11008 – Extreme-pressure performance of lubricating grease (four-ball method)
(9) IP 300 – Rolling contact fatigue test (optional)
(10) DIN 51350/6 – Shear stability of polymer-containing lubricants (optional)
(11) CEC L-45-A-99 – Transmission oil shear stability test (optional)
(12) ISO 26422:2014 – Shear stability of polymer-containing lubricants (optional)
