Induction Hardened
Bearing Rings are critical mechanical components designed for high-load industrial applications. Using advanced surface hardening techniques, the working surface of the ring achieves exceptional hardness and wear resistance, while the core retains superior toughness and strength. This combination of “hard surface, tough core” ensures high impact resistance, fracture toughness, and fatigue life, reducing the risk of
Heat Treatment deformation or cracking.
Our Soft-Turned Bearing Rings are high-precision forged bearing rings for heavy equipment, manufactured as semi-finished components ready for induction hardening. These rings provide a stable, high-quality foundation for high-performance bearings in heavy-duty machinery.
Our soft-turned TRB bearing rings follow a fully traceable and strictly controlled manufacturing workflow:
1, Incoming Material Inspection
2, Blank Cutting
3, Ring Rolling
4, Post- Forging Inspection
5, Normalizing + Annealing Heat Treatment
6, Heat Treatment Inspection (Hardness / Microstructure Verification)
7, Mechanical & Chemical Properties Testing
8, Rough Turning
9, Semi-Finish Turning
10, Comprehensive Quality Inspection:
- Dimensional Inspection
