Abstract
The most common defect of axles of wheelsets of RU1-Sh type railway cars is damage or wear of threaded openings M20 for bolts that fix retainer plates of roller bearings. It is suggested that such threaded openings should be repaired by explosion cladding with a repair sleeve and subsequent cutting a new thread in it. Fatigue tests of the repaired openings showed that their life time is almost identical to that of the new axles.
