Forged Gear Shafts & Custom Pinion Shafts

Engineered for Maximum Torque and Durability in Heavy-Duty Drivetrains

In high-load applications like rolling mills, industrial gearboxes, and mining equipment, the drive shaft is subjected to immense torsional stress and cyclic fatigue. A failure in this critical component can bring an entire production line to a halt. For ultimate reliability, the shaft and gear must be a single, seamless unit.

Yile Machinery is a specialist manufacturer of custom forged gear shafts, pinion shafts, and splined shafts. We start with high-quality forged steel and use precision CNC machining to create a monolithic component that delivers unparalleled strength and performance in the most demanding power transmission systems.

Key Features & Benefits:

• Superior Strength from Forging: Our shafts are manufactured from solid forged steel billets (e.g., 42CrMo, 34CrNiMo6, 18CrNiMo7-6). The forging process aligns the steel's grain structure, creating a component that is significantly stronger and more resistant to fatigue and shock loads than parts machined from bar stock or castings.

• Integrated Gear & Shaft Design: By machining the gear teeth directly into the shaft, we eliminate weak points like keyways or press-fits. This integral design ensures maximum torque transmission capacity and superior rotational integrity.

• Precision CNC Machining & Gear Grinding: Every feature—from the helical or spur gear teeth to the bearing journals and splines—is machined to tight tolerances on advanced CNC equipment. We offer gear grinding to achieve high AGMA/DIN quality levels for smooth, quiet, and efficient operation.

• Optimized Heat Treatment: We perform tailored heat treatment processes, such as carburizing and quenching or induction hardening, to create extremely hard, wear-resistant gear surfaces while maintaining the core toughness required to withstand high torque and impact forces.
