Our steel forged pinion gear shafts are made for gearbox. And our gear shafts are mainly made of 18CrNiMo7-6.
We can do large diameter gear shafts. The OD is from 120mm-1200mm.
The gear shafts can be manufactured as per customers' drawings. And our technologists also can design the drawings for customers.
Quality first is our principle. Our national level II lab can control the quality( chemical composition inspection, mechanical properties inspection,hardness inspection.
Product Introduction
Our steel forged pinion gear shafts are precision-engineered for application in industrial gearboxes, offering reliable power transmission in demanding environments. These critical components are primarily manufactured from the high-performance alloy steel grade 18CrNiMo7-6, selected for its exceptional hardenability, high core strength, and superior resistance to wear and fatigue—qualities essential for the rigorous operational demands placed on gear systems.
Our production capabilities include the manufacture of large-diameter gear shafts, with outer diameters (OD) available from 120mm to 1200mm, allowing us to support a wide range of heavy machinery, wind turbine, marine propulsion, and mining applications. Each gear shaft can be produced strictly in accordance with customer-supplied drawings, ensuring exact specification compliance. Furthermore, to better serve our clients, our experienced technical team is fully equipped to provide end-to-end design support, developing custom gear shaft drawings tailored to your specific mechanical requirements and operating conditions.
Quality is the fundamental principle governing every stage of our manufacturing process. This commitment is reinforced by our in-house National Level II laboratory, which enables comprehensive quality control through advanced testing procedures. Our laboratory conducts rigorous inspections, including precise chemical composition analysis, thorough mechanical properties testing, and detailed hardness verification. This integrated quality assurance system ensures that every forged pinion gear shaft we deliver meets the highest standards of performance, durability, and reliability.
