Custom Machined Heavy Forgings Carbon Steel Forging For Industrial Gearboxes Shaft

Custom Machined Carbon Steel Heavy Forging For Industrial Gearboxes Shaft. Custom Machined Carbon Steel Forging for Industrial Gearboxes These precision-engineered carbon steel forgings are custom machined to meet the demanding performance and reliability standards of heavy-duty industrial gearbox systems. Designed for high-load torque transmission, these components ensure consistent power delivery, resistance to misalignment stresses, and long-term dimensional integrity under continuous mechanical cycling.

Each unit is manufactured from high-grade materials such as 45# or 35# steel and processed through a controlled forging and heat treatment sequence to provide:

• Enhanced fatigue resistance under fluctuating torque
• Excellent concentricity and surface finish after CNC machining
• Compatible with large gear reducers, planetary gearboxes and multi-stage drive systems used in fields such as mining, metallurgy, cement and heavy manufacturing

Typical applications:
Used as key components in industrial gearboxes:

• Steel mills
• Power plants
• Cement equipment
• Mining conveyors
• Heavy-duty reducers and mechanical transmissions

Advantages:

• Customized according to customer drawings or technical requirements
• Optimized geometry for smooth torque transmission and minimal wear
• Stable performance in high-load, high-vibration industrial environments
• Competitive delivery time and reliable after-sales support

Forging process:

Raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
