Railway carriages are regularly serviced and fully overhauled. In some cases, this involves fully dismantling components, inspecting them and refitting them as reconditioned units.

One important element of such a complete overhaul is the repair of all vehicle axle assemblies. This involves reworking the professional wheels and replacing the wheel bearings supplier. Assembly of the new bearings is an exceedingly
important process in this work. These bearings are slid onto the axle and locked with a special-purpose nut. The bearing housings then have to be heated to 70 °C in order for them to be slid over the bearings. simatherm induction heaters manufactured by simatec are the ideal solution for heating the housings.

The IH 210F is suitable for workpiece weights up to 200 kg and designed for continuous duty thanks to professional fan ventilation. The bearing housings that appear somewhat misshapen owing to the support flanges for the carriage suspension are heated above the horizontal yoke since this facilitates handling during further processing. The temperature is monitored continually with the temperature probe. Of course, the parts could also be arranged around a coil and the heating process would be even somewhat faster in this case.
