On-Site Induction Hardening Service
Mobile, in-situ induction hardening for large components — mill rollers, slewing rings, large ring gears, crane wheels and machine beds — hardened at your plant across Punjab, Haryana, Delhi NCR and North India.
Need a dependable on-site induction hardening service for components too big to ship? At Thakur Industries, our mobile induction hardening units bring precision surface hardening directly to your plant. We harden large rollers, bed ways, slewing rings, large ring gears and heavy forgings in place across Ludhiana and Punjab — providing genuine in-situ hardening service that eliminates transport logistics, transit damage and costly dismantling for massive industrial components.
Efficiency at your Facility
Large rollers, bed ways, and heavy machine components are difficult to transport. Thakur Industries provides mobile on-site induction heat treatment across Ludhiana and Punjab, bringing precision technology to your floor. Our portable generators and custom coils deliver the same controlled 58–62 HRC case you would expect from our workshop — without the part ever leaving your premises.

// LARGE COMPONENTS //
Components Suited to On-Site Hardening
Our portable induction hardening service is purpose-built for heavy, oversized and fixed parts that are impractical to move. If a component is large, mounted in a line, or would be at risk in transit, on-site hardening is almost always the better route.
Mill Rollers
Long steel and rubber mill rolls hardened along the barrel without removal from the mill stand.
Slewing Rings
Raceways on large slewing bearings hardened in situ for cranes, excavators and turntables.
Large Ring & Girth Gears
Big ring and girth gears beyond workshop diameter, hardened tooth-by-tooth on location.
Crane Wheels
Tread and flange hardening of EOT crane wheels and rail wheels for long service life.
Machine Ways & Beds
Lathe beds, planer ways and press guideways hardened on the machine to preserve alignment.
Heavy Forgings & Shafts
Oversized forgings, press rollers and large shafts that cannot be safely shipped.

How On-Site Works
- 1
Survey & Planning
We review your component drawings, hardness spec and site layout, then plan the coil, power and mobilisation.
- 2
Mobilisation
Portable induction generators (25–300 kW), coils and quench systems are transported and set up on your floor.
- 3
In-Situ Hardening
Application-specific coils heat the surface to 900–950 °C with controlled quenching — only the target zone, minimal distortion.
- 4
On-Site Testing & Sign-Off
Portable Rockwell testers verify 58–62 HRC and case depth on location before we demobilise — you keep full documentation.
