The NES fretting wear tester is based on ASTM D4170 standard test method for fretting wear protection of lubricating greases. Additionally, the design allows for increased oscillation angles and can be used to validate proof-of-concept wear solutions under aggressive fretting and oscillation conditions.
The NES fretting wear tester is an ideal platform to evaluate the influence that material, dry film lubricant, coatings, plating, cage material, grease, or manufacturing processes have on wear. The machine tests two thrust ball bearings with an axial load applied at oscillation angles up to ±30°. This tester provides test results within twenty-four hours with low cost sample preparation.
