42CrMo4 rolled ring forgings for wind turbine main bearings

High-Performance Rolled Ring Forgings for Critical Industrial Applications

Our precision rolled ring forgings are engineered to deliver unmatched strength and reliability for the most demanding industrial applications. Manufactured through advanced rotary forging processes, these seamless ring components offer superior grain structure and mechanical properties compared to alternative manufacturing methods. Available in carbon steel, alloy steel, and stainless steel variants, our rolled ring forgings meet rigorous international standards including ASTM A788 and AMS 2310 specifications.

Custom rolled ring forgings can be produced in diameters from 200mm to 6000mm with wall thicknesses ranging from 25mm to 500mm, making them ideal for applications in wind turbines, heavy construction equipment, and oilfield machinery. The forging process creates continuous grain flow that follows the ring’s circumference, significantly enhancing fatigue resistance and impact strength. We offer complete material traceability with full heat treatment capabilities including normalizing, quenching, and tempering to achieve precise mechanical properties.

Key benefits of our rolled ring forgings include:

• Near-net shape production minimizing material waste and machining costs
• Superior structural integrity with no welds or joints
• Custom alloy compositions available for specialized applications
• Tight dimensional tolerances achievable for precision assemblies
• Optional machining services for ready-to-install components

Common applications include gear blanks, bearing races, pressure vessel flanges, and aerospace components where reliability is critical. Our technical team can assist with material selection, heat treatment specifications, and design optimization to ensure optimal performance in your specific application. All forgings come with complete material certification and can be supplied with additional NDT testing including ultrasonic and magnetic particle inspection.
