Inductions heaters

Induction heaters for hot mounting and dismounting of bearings

Induction heaters are heating devices designed for the rapid and uniform heating of metal components, primarily rolling bearings, without the use of an open flame. They enable the hot mounting of bearings (expanding the ring for easy sliding onto the shaft) as well as the safe dismounting of interference-fitted elements.

Application and characteristics

Induction heating relies on an electromagnetic field that generates eddy currents directly inside the heated workpiece. As a result, heat is generated within the material itself, making the process clean, repeatable, and easy to control. In practice, an induction heater is utilized in maintenance operations and servicing for tasks where mechanical assembly by brute force could damage the raceways, cage, or fitted surfaces.

Apart from bearings, these devices perform exceptionally well with rotationally symmetrical components such as gears, couplings, rings, and sleeves. Depending on the model, functions supporting process precision are available: temperature control (sensors), timers, and overheating protection procedures.

Key advantages

• Safe bearing mounting – without impacts and without the risk of damaging rolling elements.
• Rapid heating – shorter service downtime and more efficient replacement of subassemblies.
• Uniform heating – stable fitting and reduced risk of material stresses.
• Precise control – temperature sensors and a timer limit the risk of overheating the workpiece.
• Clean operation – no burners or oil baths, leading to better health and safety conditions.
• Automatic demagnetization – after the process, the bearing does not attract metal filings (depending on the device).
