25mm CNC Folding Arm HUB Mechanism High-Tensile Aluminum for Heavy-Lift Drones

25mm CNC Folding Arm HUB Mechanism | 6061-T6 Aluminum

Engineered for Industrial Reliability.
The nem. D25 Folding HUB is a high-performance folding mechanism designed for professional multirotors using 25mm (0.98") round tubes. Precision-machined from aircraft-grade 6061-T6 Aluminum Alloy, this hub provides a rock-solid connection between your frame and motor arms.
Unlike plastic alternatives, the nem. folding system eliminates vibration and "boom-drop," ensuring your flight controller stays perfectly calibrated even under heavy payloads.

Features:

High-Tensile Construction: CNC processed 6061-T6 Aluminum Alloy side parts and boom holders for maximum rigidity
Zero-Slop Folding: Provides a firm, secure fixing between the frame and 25mm (0.98") tubes.
Professional Grade: Designed specifically by nem. for heavy-lift multirotors.
Ultra-Lightweight: Only 70 grams total weight, including hardware.
Precision Machining: All parts are CNC-cut for perfect alignment and smooth folding cycles.

Specifications:

- Tube Compatibility: 25mm (0.98") Round Carbon or Aluminum tubes.
- Material: CNC Aluminum Alloy 6061-T6 + Carbon Fiber Plates.
- Weight: 70g (including hardware).
- Color: Industrial Black Anodized.
- Hardware: M3 Stainless Steel / Steel Secure Nuts.

nem. Pro-Builder’s Tip:
"When assembling your folding frame, ensure the secure nuts are tightened to a point where the fold is firm but smooth. The nem. 'secure-nut' system is designed to maintain its tension even after hundreds of folding cycles, preventing the 'loose arm' syndrome common in cheaper kits."
