Induction heaters

The function of the preheater is based on generating a (low-frequency) alternating current in the workpiece to be heated by induction. The workpiece acts as the secondary coil of a transformer. The primary coil is connected to the power supply via an electronic control system. The magnetic field induces a high current (short-circuit current) which heats the workpiece. Demagnetization is performed automatically after each heating cycle.

Induction heating is a superior, fast and controlled heating method. It is a safe and environmentally-friendly alternative to traditional heating methods such as ovens, oil baths or blow torches. These methods generate smoke, fumes or oil waste and are hazardous for your personal safety and a healthy working environment. It is common knowledge that a correct mounting method extends the bearing life. Controlled stress-free heating prevents unnecessary damage, while retaining the original bearing lubrication. Ideal for sealed bearings (2RS-ZZ). Bearing manufacturers recommend controlled induction heating as the best practice for bearing mounting.

Yes, Induction heaters are used for assembly (Low Frequency) and/or disassembly (Mid Frequency) of bearings, gears, sprockets and other machine components. 

The BETEX MF Quick-Heater (Mid-Frequency) consists of a generator with a fixed or flexible inductor. The compact dimensions make it easy to move. MF Quick-Heaters save time because they can be used quickly (fewer actions) and heat faster than conventional methods. The energy consumption is much more efficient because less power is used. One of the major advantages of this type of induction heater is that they are not limited to cylindrical shaped components: flexible inductors can be wrapped around large or odd sized components.

Bearing manufacturers advise: 

Bearings generally should only be heated up to a maximum temperature of 120ºC (248ºF).  

If in doubt, contact the bearing manufacturer.
