What Is an Induction Heater?
An induction heater uses electromagnetic induction to uniformly heat a bearing, causing it to expand so it slides freely onto the shaft. Once it cools, the bearing contracts and achieves the required interference fit. This method is faster, safer, and more uniform than hot oil baths or open flames.
Best Practices
Never exceed 125C. Always demagnetize after heating. Use a temperature probe or indicator strip. See the Bearing Installation Guide for the complete hot-mounting procedure. SMS Bearings supplies SKF TIH induction heaters in the UAE.
Frequently Asked Questions
How hot should a bearing be heated for mounting?
Typically 80-110C above ambient temperature, but never exceed 125C to avoid damage to the bearing's heat treatment. The exact temperature depends on the interference fit and bearing size. SKF TIH induction heaters have built-in temperature control and automatic demagnetization.
