Induction Hardening for Bearings
Achieve extreme surface hardness and dimensional stability for bearing races, rings, and seats. Our high-frequency induction process delivers HRC 60+ results optimized for heavy-load industrial and automotive bearings.
Why Precision Matters
Bearing races operate under extreme contact stress. At Thakur Industries, we understand that even a 5-micron deviation in case depth can lead to premature failure.
- Uniform Hardness: Eliminating soft zones in the raceway.
- Dimensional Stability: Minimal warping for easier post-hardening grinding.
- Fatigue Life: Optimized martensitic structure to resist pitting.
- Localized Control: Hardening only the seat/race, leaving the flange ductile.
Materials & Hardness Specs
EN31 / 52100
The gold standard for bearing steel. We achieve HRC 60–64 with extreme metallurgical stability.
EN24 / 4340
Used for high-impact industrial bearings. Targeted hardening for HRC 55–60 requirements.
Case Hardening Alloys
Precise induction depth control for 20MnCr5 or 8620 bearing seats.
Case Depth Control
Shallow 0.5mm for precision pins or deep 5mm for heavy mill bearings.
Induction Bores
Specialized ID (Internal Diameter) hardening for bearing seats in hubs.
Repeatability
99.8% consistency across high-volume OEM bearing production runs.
Inspection & Traceability
For OEM and export-grade bearings, we provide full digital documentation:
- Hardness Maps: Verification across multiple race points.
- Batch Reports: Detailed cycle data for every lot.
- NDT Testing: Magnetic particle inspection for crack-free assurance.
- Microstructure Analysis: Validation of grain refinement.
