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:
Typical applications:
Used as key components in industrial gearboxes:
