Material-Based Classification

• Stainless Steel Custom Shafts

Made of 304/316 stainless steel, featuring corrosion resistance and high strength. CNC precision-machined and polished with tolerances up to ±0.01mm. Ideal for food machinery and chemical equipment, ensuring long-lasting stable connections.

• Carbon/Alloy Steel Custom Shafts

Crafted from 45# or 40Cr steel, with quenching/tempering for high hardness, wear resistance and fatigue resistance. Withstand heavy and alternating loads. Widely used in construction machinery and auto parts for transmission and articulation. Custom irregular designs available.

Structure-Based Classification

• Custom Shafts with Pin Holes (Type B)

With standard holes for cotter pins/R-clips for anti-loosening and anti-disengagement, enhancing reliability in vibrating environments. Custom diameters 3–100mm, lengths 10–300mm. Perfect for excavators and vehicle suspensions in dynamic articulation.

• Solid Custom Shafts (Type A)

Smooth round head without holes, with precision fit and low friction. Surface finish up to Ra0.8. Ideal for static connections and precision mechanisms like medical devices and automation hinges. Custom knurled, threaded or stepped designs available.

Application-Based Classification

• Construction Machinery Custom Shafts

Designed for excavators and cranes, featuring high strength, impact resistance and heavy load tolerance. Alloy steel forged + heat-treated, with Dacromet/zinc plating. Custom eccentric, splined or flanged structures for heavy-duty articulation and transmission.

• Precision Equipment Custom Shafts

For automation equipment and instruments, with ultra-high precision (±0.005mm), low runout and high concentricity. Stainless steel/aluminum with mirror polishing. Ideal for high-speed rotation and precision positioning. Custom micro sizes (<5mm diameter) available.
