【 摘 要 】

At present, axle units of freight cars undergo a complete checkup with disassembling and visual inspection of the bearing parts every five years. During an annual interim checkup, external inspection of an axle box with removed cap is carried out and the lubricant condition is checked. The state of the rolling surfaces of bearings during an interim checkup should be assessed using the known methods of nondestructive testing.
