Forged Drive Shafts for Rolling Mills

Engineered for Maximum Torque and Unmatched Reliability

In a steel mill, the drive shaft is the heart of the rolling process, transferring immense torque under constant shock loads and high temperatures. A failure is not an option. It results in catastrophic downtime, lost production, and significant safety risks. The key to a shaft's survival is its material integrity and manufacturing process.

Yile Machinery is a specialized manufacturer of heavy-duty forged drive shafts, engineered specifically for the extreme demands of hot and cold rolling mills. We produce robust, custom-made shafts that serve as reliable, long-lasting replacements for your critical powertrain components.

Key Features & Benefits:

• Superior Strength Through Forging: We start with solid billets of high-grade alloy steel. The forging process creates a dense, uniform grain structure that is free of internal defects, providing vastly superior fatigue resistance and impact toughness compared to cast or fabricated shafts.

• High-Torque Alloy Steels: We manufacture drive shafts from proven, high-strength alloy steels such as 42CrMo, 35CrMo, and 40CrNiMo, selected to provide the optimal balance of hardness, toughness, and torsional strength for your specific application.

• Advanced Heat Treatment: Each shaft undergoes a controlled quenching and tempering process to achieve exceptional surface hardness for wear resistance on splines and bearing journals, while maintaining a ductile core to absorb the intense shock loads inherent in the rolling process.

• Precision Machining for Perfect Fit: Using large-scale CNC lathes and milling centers, we machine all features—including splines, keyways, and bearing surfaces—to extremely tight tolerances. This ensures a perfect fit, balanced rotation, and reduced vibration, extending the life of the entire drive system.

• Custom "Made-to-Drawing" Manufacturing: As a specialist supplier to the steel industry, we manufacture drive shafts and universal joint shafts (Cardan shafts) precisely to your engineering drawings or can reverse-engineer them from a sample part.
