Precision Inner Ring Forgings for Heavy-Duty Industrial Applications

High-Strength Components Engineered for Performance & Reliability

Manufactured to the highest quality standards, our inner ring forgings deliver exceptional durability and precision for demanding mechanical systems. Forged from premium alloy steels and rigorously heat-treated, these components ensure superior strength, wear resistance, and dimensional accuracy in extreme operating conditions.

Key Features & Benefits

✔ Premium Material Construction

  • Forged from high-grade alloy steel (AISI 4140, 4340, 52100) or stainless steel

  • Precision heat treatment (quenching & tempering) for optimal hardness (HRC 32-58)

  • Ultrasonic tested for internal defects

✔ Precision Manufacturing

  • CNC machined to tight tolerances (ISO 2768-mK)

  • Ground or turned finishes available (Ra 0.8–3.2 μm)

  • 100% dimensional inspection

✔ Superior Performance

  • High load-bearing capacity

  • Excellent fatigue resistance

  • Corrosion-resistant options available

✔ Customization Options

  • Diameters: 50 mm to 2000 mm

  • Custom wall thicknesses and profiles

  • Special surface treatments (black oxide, zinc plating)

Industrial Applications

  • Bearing assemblies

  • Gearbox components

  • Heavy machinery rotating elements

  • Wind turbine hubs

  • Mining equipment

Why Choose Our Inner Ring Forgings?

  • Certified Quality: ISO 9001:2015 compliant with full traceability
