Fretting Wear Protection by Lubricating Greases Tester        ASTM D***0
Product model: JF***6

Product Introduction
This instrument is used to evaluate the anti-friction wear characteristics of the grease when the bearing swings. Under the specified test conditions, it can distinguish the low and medium-high anti-fretting wear capabilities of different greases. This test has been applied to predict the anti-friction wear resistance of automobile wheel bearing grease in long-distance transportation. The test principle is to make two sets of thrust ball bearings with test grease at an amplitude of 0.*1, an oscillating frequency of *0HZ, a load of ***0N, and room temperature conditions for oscillating motion. The test time is *2 hours. The average value of the sum of the mass loss of the two sets of bearing races is used as the evaluation of the anti-fretting wear performance of the test grease.
