Product Description
Custom sizes available | After‑sales guarantee | Factory direct – a coupling you can trust
The DXC series is a one‑piece metal rigid clamp coupling designed for high‑precision power transmission. Zero backlash, no power/motion loss, and extremely high rigidity.
⚠️ Note: This rigid coupling does NOT absorb misalignment – precise shaft alignment is mandatory.
Key Advantages
✅ Zero Backlash & High Rigidity
One‑piece aluminum structure with no elastic elements – absolute zero backlash. Ideal for high‑stiffness, high‑response servo/stepper systems.
✅ High‑Strength Aluminum Alloy
Made of high‑strength aluminum alloy – corrosion resistant, good thermal conductivity, lightweight, reducing inertia for dynamic applications.
✅ Class 12.9 High‑Strength Screws
Clamping screws are grade 12.9 alloy steel – smooth, burr‑free, uniform clamping force, no loosening under vibration.
✅ Easy Installation & Removal
Compact, lightweight, clamp‑type design – simply tighten the screws for fast mounting, adjustment, and maintenance.

FAQ
Q: Can the DXC rigid coupling compensate for shaft misalignment?
A: No. It is a zero‑backlash, high‑rigidity coupling and does not absorb misalignment. Precise alignment is required.
Q: Suitable for high‑torque servo motors?
A: Yes. The DXC series is designed for high torque transmission with no power loss.
Q: What is the MOQ for custom couplings?
A: No MOQ for standard sizes; custom orders typically start at 10 pieces.
