35mm Inner Height Series

35mm Series Cable Chain CNC Carriers – Bridge Open Type

Medium-Duty Cable Protection Built with Reinforced PA66 Nylon

For medium-duty CNC machinery, choosing a reliable cable chain CNC system is essential to guard wiring, avoid dynamic fatigue, and prevent operational downtime. The 35mm series cable chain CNC carrier (bridge open type) is designed specifically as a medium-duty cable management solution. It bridges the gap between narrow 25mm light-duty tracks and heavy-duty 45mm/55mm series, making it the ideal choice for medium-to-large cable bundles.

With an internal height of 35mm and flexible widths from 50mm to 300mm, this cable track comfortably holds power cables, signal wires, and air hoses up to 31.5mm outer diameter. It handles up to 10–14 standard cables simultaneously, making it suitable for CNC milling machines, routers, engravers, and automated production machinery.

Engineered for Strength: 30% Glass-Fiber Reinforced Nylon

Unlike low-cost, economy plastic drag chains that wear out rapidly under continuous motion, our cable chain CNC carriers are injection-molded from premium PA66 nylon reinforced with 30% glass fibers. This industrial-grade compound gives the chain significant performance advantages over basic nylon alternatives:

Superior Wear Resistance & Service Life: High tensile strength and impact resistance deliver an operating service life exceeding 10 million dynamic cycles under normal operating conditions.
Higher Load-Bearing Capacity: Glass-fiber reinforcement prevents sagging over long travel distances, supporting heavier cable bundles with minimal structural flex.
Wide Thermal Tolerance: Operates reliably from -40°C to +130°C, performing consistently in unheated cold workshops and high-heat machining environments alike.
Oil & Chemical Resistance: Highly resistant to coolants, cutting fluids, lubricants, and mild chemicals without swelling or degradation.
Low Operating Noise: Features natural vibration-damping properties that maintain working noise levels below 60dB, ideal for modern automated production environments.

Open Bridge Design Advantages

The bridge open configuration features snap-open crossbars on both top and bottom that can be easily popped open with a standard flathead screwdriver:

Quick Cable Layout: Lay cables directly into the track without pulling them through the entire length, cutting maintenance and installation time.
Efficient Heat Dissipation: Open airflow keeps high-flex cables cool during continuous, high-speed traverse motion.
Reduced Drive System Load: Lightweight relative to steel drag chains, reducing motor load and permitting faster machine acceleration.
