80 Series Drag Chain - Heavy-Duty Bridge Cable Track for Large CNC & Automation

The 80 series drag chain is a premium, open-style cable management solution engineered from high-strength reinforced PA66 nylon. Designed specifically for heavy-duty industrial machinery, this open-bridge energy chain delivers high mechanical tensile strength, outstanding wear resistance, and long service life during continuous high-speed movement. Featuring an 80mm inner height, it organizes and protects large electrical cable bundles, thick hydraulic lines, and pneumatic hoses from structural fatigue and premature friction on demanding CNC equipment.

Premium Raw Materials & High-Rigidity Molding

Our 80 series drag chain tracks are manufactured from 100% virgin PA66 raw polymer enriched with anti-wear, flame-retardant, and heat-stabilizing compounds. This high-density construction ensures exceptional torsional stability, preventing chain sagging or deformation across long unsupported travel distances. The material resists chemical degradation from cutting fluids, synthetic oils, and harsh industrial solvents.

Modular Design & Convenient Cable Installation

Featuring a open bridge design with snap-open crossbars on both sides, the 80 series drag chain significantly reduces maintenance downtime. Field technicians can rapidly lay in new wiring, adjust internal vertical separators, or perform routine inspections without disassembling the entire track or disconnecting machinery cables.

Heavy-Duty Application & Factory-Direct Delivery

With inner widths spanning from 75mm to 400mm and bending radii ranging from R150 to R400, this robust track handles long strokes and demanding load capacities seamlessly. Typical applications include heavy gantry machining centers, large-format fiber laser cutters, automated warehouse equipment, gantry robots, and stone carving machinery. For environments exposed to high flying chips, metal swarf, or sparks, consider our 80 series enclosed drag chain for complete internal protection.

As a factory-direct OEM supplier, we maintain extensive inventory for standard configurations to support fast global dispatch, competitive bulk pricing, and custom options like steel mounting brackets, fiber clips, and custom color branding.
