We developed a novel axle box bearing endurance test equipment in 2010. It enables a test under a high speed condition of over 320km/h. In addition, it can provide an axial/radial load and vibration under actual conditions. With the aim of ensuring the quality assurance/control and the future development of the bearings, a long-term durability test of axle box bearings is currently in progress by using this equipment. The structure and the operation of the equipment and the progress of the test are reported in this paper.
