【THB】Failure Analysis
Fretting wear marks on the inner ring indicate a loose running fit between the inner ring and the shaft, which has been double-checked from the analysis software-based load test results on the bearing under the specified duty.
This bearing is designed to operate under the point load. In case of a loose running fit, the inner ring tends to slide a little with the continuous introduction of point loads, leading to unstable motion between the rolling body and the raceway, thus accelerating premature raceway wear.
