From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming
Advanced Engineering Materials, EarlyView.Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...
