Laboratory endurance tests of six railcar roller bearings that had previously suffered physical damage or were otherwise degraded as a result of actual railroad service were conducted. The primary objective of the test was to obtain a better understanding of the railcar roller-bearing failure process(es) and the manner in which bearing defects progress. A 150-h test with 117 872N (26,500 pounds) radial load (equivalent full carload) at 528 rpm (equivalent to approximately 84 km/h or 52 mph) was planned for each bearing. Only one bearing actually failed to complete the 150-h or 12,550-km (7,800-mi) test. All bearings exhibited further measurable degradation or defect progression during the course of the tests.
