Rolling stock maintenance is an important part of the railway system. Unthinkable what would happen if this was neglected: stalled trains would block rails and existing timetables would become a mess. This is why regular maintenance is necessary in order to maintain a reliable train park.For removing and installing railway bearing sets and labyrinth rings, special induction heaters can be used. Middle frequency induction heating technology is a safe and cost effective heating method that improves the quality of installation.Using accurate design simulation software capable of running parametric studies across a range of parameters simultaneously, such as bearing clearances and manufacturing tolerances, is essential.
