We specialize in the production of large-diameter forged main shafts, offering a comprehensive range with outer diameters (OD) spanning from 120mm to 1200mm. This capability allows us to accommodate a wide spectrum of heavy-duty industrial applications, providing robust and reliable solutions tailored to meet diverse operational demands.
Our manufacturing process is highly flexible and customer-centric. We can precisely manufacture main shafts according to customers' detailed drawings and specifications. Moreover, to better support our clients throughout the product development lifecycle, our team of experienced technologists offers complimentary design services. This means we are fully equipped to create custom drawings and provide technical solutions that perfectly align with the unique requirements and functional objectives of your project.
Quality is the cornerstone of our operational philosophy. Adhering strictly to the principle of "Quality First," we have established rigorous quality assurance systems. This commitment is backed by our in-house National Level II Laboratory, which enables us to conduct comprehensive and precise quality control inspections at every critical stage of the manufacturing process. Our laboratory performs meticulous checks, including advanced chemical composition analysis, extensive mechanical properties testing, and thorough hardness inspections. This ensures that every forged main shaft we deliver not only meets but consistently exceeds the highest industry standards for material integrity, structural reliability, and long-term performance.
