Induction Heater for Shrink Fitting –
Precision Heating for Gears, Couplings & Assemblies
Shrink fitting is a critical process in industrial assembly where components like gears, couplings, sleeves, and bearings are expanded through controlled heating for precise interference fitting. Any inconsistency in heating can lead to misalignment, surface damage, or premature failure.
At Precision Instruments & Allieds, we manufacture induction heaters specifically engineered for shrink fitting applications, ensuring uniform expansion, precise temperature control, and repeatable assembly results.
Our systems are widely used in automotive manufacturing, heavy engineering, steel plants, gearbox manufacturing, and OEM assembly lines, where precision and reliability are critical.
With induction heating, shrink fitting becomes faster, safer, and more accurate compared to flame or oven heating, significantly improving productivity and reducing rejection rates.

What is Induction Heating for Shrink Fitting?
An induction heater for shrink fitting is used to heat metal components in a controlled manner so they expand and can be easily assembled onto shafts or other parts. Once cooled, the component contracts, creating a tight and secure interference fit.
