Precision Forged and CNC Machined Gear Shaft
The precision gear shaft is a vital component in modern power transmission systems. At Weforging, every gear shaft is manufactured through our integrated forging + CNC machining + testing process to ensure superior strength, dimensional accuracy, and surface finish. Combining advanced forging techniques with precision gear cutting, we deliver components that maintain high efficiency and reliability under heavy mechanical loads. Weforging gear shafts are trusted by OEM customers in automotive, industrial, and heavy machinery sectors, offering consistent performance and long-term durability.
What Is a Gear Shaft
A gear shaft is a combined gear and shaft structure that transmits torque and motion between rotating components. It integrates the gear teeth directly with the shaft body, achieving both power transmission and mechanical support in one unit.
At Weforging, our gear shafts are designed to maintain tight concentricity, optimized tooth geometry, and smooth engagement for long-term reliability.
Manufacturing Process
Weforging applies a strict production workflow to ensure precision and consistency:
Material preparation – alloy or carbon steel (42CrMo, 20CrMnTi, 8620, 4140).
Closed-die forging – forms the shaft and gear structure with refined grain flow.
Heat treatment – normalizing, quenching, and tempering to enhance hardness and fatigue strength.
CNC machining – turning, milling, and drilling for perfect fit and alignment.
Gear cutting & grinding – achieving precise tooth profile and surface accuracy.
Inspection & testing – dimensional check, hardness test, and tooth contact verification
