ASTM D4170 Lubricating Grease Fretting Wear Resistance Tester | Grease Fretting Corrosion Testing Equipment

Fretting Wear Resistance Tester

I. Introduction:

Lubricating Grease Fretting Wear Resistance Tester is used to evaluate the anti-fretting wear characteristics of grease when the bearing swings. Under the specified test conditions, it can distinguish the low, medium and high anti-fretting wear ability of different greases. This test has been applied to predict the anti-fretting performance of automotive wheel bearing greases in long-distance transportation. The test principle is to swing two sets of thrust ball bearings with test grease at an amplitude of 0.21, a swing frequency of 30HZ, a load of 2450N, and room temperature, and the test time is 22 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.
