DS/DL Aluminum Alloy Shaft Coupling
Our DS/DL aluminum alloy shaft coupling are made of high-strength aviation aluminum and are designed specifically for servo motors, stepper motors, and precision transmission systems. This model of product features lightweight, zero backlash, and high torsional rigidity, making it suitable for high-precision applications such as automation equipment, robots, and CNC machine tools.
- Lightweight design – made of aviation grade aluminum alloy material, with a weight reduction of 40% compared to steel couplings
- Zero backlash transmission – eliminates transmission clearance to ensure high-precision positioning.
- High torsional rigidity – optimized structural design, increased torsional stiffness by 30%
- Maintenance free operation – long-term use without lubrication, reducing maintenance costs.
- Anti fatigue and durable – special heat treatment process, suitable for high-frequency start stop working conditions.

Product Description
The DS/DL aluminum alloy shaft coupling is a high-performance coupling solution developed by us based on the transmission requirements of high-end equipment. It uses 7075-T6 aviation aluminum alloy forging blanks, which are precision CNC processed and anodized to achieve ultimate lightweight while ensuring strength. It reduces weight by 40% compared to traditional steel couplings, significantly reduces rotational inertia, and improves the dynamic response performance of servo systems.
This series of products adopts a gapless elastic buffer design and achieves zero backlash transmission through high-precision conical clamping sleeves or diaphragm structures. The repeated positioning accuracy can reach ± 0.02mm, perfectly adapting to high-precision CNC machine tools, industrial robot joints and other scenarios that require extremely high transmission stability.
