Induction heating Many ring-shaped components are mounted with a tight fit on the shaft. Larger rolling bearings, in particular, are considerably easier to mount when preheated. Induction heating is superior to conventional methods, such as heating furnaces, heating plates, and oil baths, and is regarded among bearing manufacturers as the best and safest method for mounting bearings. Induction heating is also suitable for frequent heating.
The following parts can be heated using this method:
complete rolling bearings, including greased bearings
inner rings of cylindrical roller bearings or needle roller bearings
other ring-shaped, ferromagnetic steel parts, such as gears and bushings
2 series are available: HEATER-BASIC and HEATER-SMART. HEATER-BASIC is equipped with a robust membrane keyboard for straightforward operation and offers 2 heating methods. HEATER-SMART is equipped with a touch-sensitive screen and offers 4 heating methods, making it particularly suitable for heating rolling bearingswith a low radial internal clearance.
HEATER-SMART also features a documentation facility. The HEATER-BASIC and HEATER-SMART series offer the following features:
fast and uniform heating through automatic power regulation
enhanced safety for workpiece and fitter through controlled heating
preservation of the bearing’s original lubrication
energy efficiency and environmentally friendly operation
cost savings due to low energy consumption
different versions for workpiece weights up to 1600 kg
