Shaft Hardening Job Work in Ludhiana
Precision induction hardening for transmission shafts, axles and splined shafts — 52–60 HRC with controlled 1–5 mm case depth and minimal distortion. Trusted job work in EN8, EN19, EN24 and 4140 for automotive, tractor and industrial drivetrains across Punjab.
Looking for dependable shaft hardening job work in Ludhiana? At Thakur Industries, our precision induction shaft hardening raises journal, spline and bearing-seat surfaces to 52–60 HRC while keeping the core tough enough to absorb torsional and bending loads. We serve Ludhiana’s automotive, tractor and industrial OEM clusters with consistent, high-accuracy hardening for transmission shafts, axles, splined shafts, spindles and custom drivetrain profiles.
Types of Shafts We Harden
Induction hardening uses electromagnetic fields to heat only the outer surface layer of a shaft, so we can target journals and splines while protecting the rest of the component. We provide customised hardening profiles for:
- Transmission Shafts
- Axles & Half Shafts
- Splined Shafts
- Spindles & Drive Shafts
- Pump & Motor Shafts
- Rollers & Long Shafts

The Induction Advantage
Localized Heating
Hardens only the critical journals, splines or bearing seats, protecting the rest of the shaft.
Low Distortion
Targeted heat prevents thermal warping, maintaining tight runout and concentricity tolerances.
High Productivity
Fast cycle times (seconds per part) enable high-volume OEM manufacturing throughput.
Digital Precision
PLC-controlled cycles ensure identical 52–60 HRC and case depth for every shaft.
Tough Core
A hard martensitic surface over a ductile core resists wear without losing impact strength.
Energy Efficient
Optimized power usage focused strictly on the surface area being hardened.
Quality Verification
We maintain full traceability for every OEM batch. Each hardened shaft is verified against your drawing and internal standards using precision laboratory equipment before dispatch.
// PRICING & TURNAROUND //
Shaft Hardening Rates & Lead Time
We offer competitive shaft hardening rates for both prototype batches and bulk OEM production. Final pricing depends on shaft weight, diameter, hardened length, case depth, steel grade and quantity — share your drawing for an exact quote within 24 hours.
Pricing Basis
Per kg or per piece, with reduced rates on bulk and repeat OEM orders.
Minimum Order
No rigid minimum — single trial shafts to multi-thousand-piece lots accepted.
Turnaround
Standard 2–4 working days; urgent same-week jobs for regular clients.
Quality Assurance
Surface Hardness
HRC verification across journals and spline flanks for uniform wear resistance.
Case-Depth Control
Microhardness traverse confirms the 1–5 mm effective case to specification.
Runout Inspection
Concentricity and straightness checks safeguard drivetrain alignment.
Traceability
Digital logging of every cycle for full OEM documentation and audits.
// PROCESS //
Our Shaft Hardening Process
Component Assessment
We inspect your shaft dimensions, material grade (EN8/EN19/EN24/4140) and specify the required 1–5 mm case depth.
Induction Hardening
High-frequency induction coils heat the shaft surface to 850–950 °C, followed by immediate polymer quenching for uniform 52–60 HRC.
Hardness Testing & Dispatch
We perform Rockwell HRC tests, case-depth and runout inspection, then dispatch within 2–4 working days with a test report.
