Induction Heat Treating Technologies For Large Gears Inductoheat has been manufacturing induction heating systems for large gears for over 30 years. Our accurately controlled, induction gear hardening systems can selectively harden specific areas of your gear teeth and bearing race with minimum shape distortion, producing a fine-grained martensitic layer. Additional benefits include required hardness and compressive surface stresses, improved contact fatigue strength and wear resistance, and elimination of premature gearbox failure.
