Roller Stock Bearing removal.

Before machining the wheels of rolling stock, the bearing rings (NU and NUP) and the labyrinth rings have to be dismantled. This is important for the customer as the rings must be dismantled without damage for reuse.

Solution TM: By sliding an induction coil over the inner ring or labyrinth ring and connecting it to a mid-frequency generator, we are able to heat only the inner ring while the shaft stays cool. After heating it is easy to slide the ring and coil from the shaft.          

Advantage: Inner ring can be used again, no damage or overheating.

                   Induction coil is relative light and easy to handle.

    A continuously “Temperature Controlled” heating and dismounting process, no chance of overheating the ring or shaft
