A bearing induction heater is a device used to heat rolling bearings and other ring-shaped metal parts efficiently by using an electromagnetic field. This method causes the workpiece to heat directly and evenly, allowing for easier and safer mounting by expanding the bearing so it fits on shafts or components without excessive force. Induction heating is preferred because it is clean, fast, precise, and significantly reduces the risk of damaging the bearings or shafts compared to conventional heating methods like hotplates, ovens, or open flames.
