Evaluation of Fretting Protection Property of Lubricating Grease Applied to Thrust Ball Bearing

Fretting wear is often the case when ball-and-roller bearings oscillate under grease lubrication. Against the backdrop of fretting wear on the wheel bearings of automobiles caused by rail transportation, the ASTM D4170 fretting test method was developed to evaluate the fretting protection property o...
