18 Series Silent Drag Chain: Low-Noise & High-Speed Cable Carriers
The 18 series silent drag chain is designed specifically for automated equipment demanding high-frequency dynamic motion, smooth articulation, and minimal operating noise. Built with an internal height of 18mm and a micro 17mm pitch, this low-noise cable carrier significantly reduces vibration during rapid movements, making it an ideal protective solution for sensitive power cables and signal lines in compact installation spaces.
Key Engineering Features & Structural Advantages
Engineered from high-rigidity modified polyamide (PA66 reinforced), the YDLHS18 series offers exceptional tensile strength, wear resistance, and long service life. Its primary architectural features include:
- Bridge-Type Open Design: The open bridge structure allows maximum airflow, superior heat dissipation, and quick visual inspection or replacement of cables without disassembling the entire carrier.
- Micro 17mm Pitch Configuration: Small pitch engineering drastically minimizes the "polygonal effect" during rotation, ensuring ultra-smooth transitions, low acoustic emission (below 30–40 dB), and reduced wear on guiding systems.
- Integrated Buffering & Silent Stops: Multi-point limiting mechanisms and built-in dampening structures absorb kinetic impact, preventing noisy link-to-link collisions during acceleration.
- Modular Internal Separation: Can be fitted with vertical and horizontal dividers to cleanly isolate power, control, and pneumatic lines, preventing twisting and frictional damage.
