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 bearing tings for induction hardening are produced following strict quality standards:
- Precision forging : High-carbon alloy steel is forged to create dense, uniform internal metallurgical structures.
- Rough Machining & Soft Turning: Soft-state turning and initial machining provide precise dimensional allowance for final induction hardening while maintaining surface quality.
- Heat Treatment Preparation: Prepares the semi-finished ring for induction hardening to achieve optimal hardness and fatigue resistance.
- Full-Process Quality Control: From raw material inspection to finished product storage, we implement traceable inspections including dimensional checks, ultrasonic testing, magnetic particle inspection, and chemical composition analysis to meet ISO standards.
