Bearing Induction Heaters

Bearing induction heaters are electrical tools that use an alternating magnetic field to warm conductive rings for expansion before shaft mounting. Controlled heating reduces installation force, while temperature sensing and an automatic demagnetising cycle help protect the bearing and keep loose metallic debris from remaining attracted.

Questions about bearing induction heaters

What should I send to identify bearing induction heaters?

Send workpiece weight and dimensions, minimum bore, electrical supply, mounting orientation, probe and control needs. Provide both workpiece bore and outside dimensions, since weight alone does not confirm that it fits the heater yoke. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select bearing induction heaters?

Match power, yoke size, workpiece capacity, supply and controls to the largest bearing or ring that will be heated. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
