45mm Inner Height Series

CNC Cable Chain 45mm Series – Bridge Reinforced Nylon Type

Middle-Duty Cable Protection Built with Glass-Fiber Reinforced PA66

For middle-duty industrial machinery and long-stroke motion systems, selecting a high-load cnc cable chain is crucial to shield power cables, hydraulic lines, and pneumatic hoses from structural sagging and mechanical wear. The 45mm series cnc cable chain (bridge open type) is specifically engineered as a robust cable management carrier for large equipment. It provides a spacious routing solution that bridges the gap between medium 35mm carriers and ultra-heavy 55mm systems.

Featuring an internal height of 45mm and generous **internal widths ranging from 50mm to 300mm**, this heavy-duty cnc cable chain comfortably houses thick cables and hoses up to 40.5mm outer diameter. It handles large bundles of 14 to 20 standard cables simultaneously, making it the premier choice for gantry milling machines, heavy CNC lathes, large machining centers, and industrial laser cutting systems.

Engineered for Strength: Superior Performance of Reinforced Nylon

Unlike standard plastic cable tracks that flex excessively or wear down under heavy loads, our cnc cable chain carriers are precision injection-molded from premium PA66 nylon reinforced with 30% glass fibers. This industrial compound delivers far superior mechanical performance compared to basic, economical plastics:

Higher Load-Bearing Capacity & Rigidity: Glass-fiber reinforcement dramatically improves tensile and flexural strength, preventing chain sagging across long unsupported spans under heavy cable loads.
Extended Dynamic Service Life: Exceptional fatigue strength and impact resistance ensure a continuous dynamic operating life exceeding 10 million bending cycles under standard conditions.
Superior Wear & Abrasion Resistance: High surface hardness minimizes friction at link connection points, drastically reducing long-term joint wear.
Broad Temperature Stability: Performs reliably across extreme thermal environments from -40°C up to +130°C without brittleness or heat deformation.
Fluid & Chemical Endurance: Highly resistant to cutting coolants, synthetic lubricants, oils, and mild industrial chemicals without swelling or cracking.
Flame Retardant & Quiet Operation: Rated UL94 V-2 for flame retardancy, featuring natural vibration damping that keeps running noise strictly below 60dB.

Bridge Open Design – Practical Advantages

The bridge open configuration features snap-open crossbars on both top and bottom sides, easily opened using a standard flathead screwdriver:

Effortless Cable Installation: Lay heavy cable bundles directly into the carrier without threading them through long sections, saving significant installation and maintenance labor.
Optimal Heat Dissipation: The open frame maximizes airflow to keep high-flex power cables cool during continuous high-speed movement.
Lightweight Efficiency: Weighs roughly one-third of traditional steel cable chains, reducing drive motor load and enabling faster machine acceleration and deceleration rates.

Note: R100, R150, and R200 are the most widely selected bending radii for the 45mm series. For internal widths over 125mm, selecting a radius of R150 or larger is recommended for smooth dynamic motion.

Common Applications

The 45mm series cnc cable chain is widely specified across heavy-duty industrial machinery, including large CNC machining centers, gantry mills, heavy CNC lathes, plasma and laser cutters, woodworking CNC routers, and automated material handling equipment.
