Precision CNC Machined Crank Arm – Durable Performance for Demanding Applications
The crank arm is a core component in various mechanical systems, especially in bicycles, motorcycles, and electric mobility equipment. Its main function is to convert linear motion into rotational force, making it essential for efficient power transmission and smooth motion control.
At HKAA, we specialize in the CNC machining of high-precision crank arms, offering full customization in dimensions, materials (such as aluminum alloy, stainless steel, or titanium), and surface treatments. Whether you're developing parts for performance bikes or industrial machinery, our CNC capabilities ensure every crank arm meets tight tolerances, excellent surface finishes, and optimal strength.
We also support anodizing, sandblasting, and custom logo engraving for your crank arm projects, making them not only functional but also visually refined. With our ISO and AS9100-certified production processes, we are a trusted global supplier of CNC crank arm components for both OEM and aftermarket applications.
