Heavy-Duty Forged Stainless Steel Shaft

Forging distinguishes this shaft from cast alternatives by eliminating internal defects like porosity or cracks, resulting in superior mechanical performance. The Forged Stainless Steel material offers exceptional corrosion resistance, critical for motors in humid, chemical, or outdoor environments. Additionally, the forging process aligns the metal’s grain structure, boosting fatigue resistance—essential for high-speed, continuous-operation motors in appliances, autos, and industrial machinery.

Core Features

Precision Forged Manufacturing

The Forged Stainless Steel Motor Shaft undergoes precision forging, ensuring uniform grain structure and enhanced load-bearing capacity. This process delivers higher tensile strength and impact resistance compared to cast or machined shafts, making it suitable for heavy-duty motor applications.

Ultra-High Precision Tolerances

With a High Precision Motor Shaft design, the shaft boasts dimensional tolerances of +/-0.001mm, roundness of 0.001mm, and straightness of 0.001mm. This level of accuracy ensures smooth rotation, reduces friction, and extends the lifespan of motor bearings and other components.

Versatile Material Selection

Beyond Stainless Steel Shaft, materials include carbon steel, brass, or custom options per customer requirements. Stainless steel variants offer optimal corrosion resistance, while carbon steel provides cost-effective strength for general applications.

Custom Forged Shaft Solutions

We specialize in Custom Forged Shaft production, supporting OEM services with customer-provided drawings. Whether adjusting diameter, length, or surface treatment, our engineering team tailors the shaft to fit unique motor designs—from micro motors to industrial machinery.

Advanced Heat Treatment

Options include Quenched Hardening and point hardening, enhancing the shaft’s surface hardness (measured in HRC/HV) and wear resistance. Heat treatment is tailored to application needs, ensuring the shaft withstands high torque and friction without deformation.

Multiple Surface Treatment Options

Surface finishes include Zinc-Plated Motor Shaft, nigrescence, chrome plating, and nickel plating. Zinc plating offers cost-effective corrosion protection, while chrome plating enhances wear resistance—ideal for shafts in high-friction environments.

RoHS & ISO 9001 Certification

As a RoHS-Certified Motor Shaft and ISO 9001 Motor Shaft, it meets international environmental and quality standards. SGS testing validates compliance, ensuring the shaft is safe for use in electronics, appliances, and automotive applications worldwide.
