35 Series Medium-Duty Bridge Plastic Drag Chain - Standard Nylon Cable Carrier

The 35 series plastic drag chain is a standard medium-duty, open-bridge cable management system engineered with a 35mm internal height. Positioned between micro/light-duty carriers and heavy-duty steel-reinforced chains, this highly popular medium-duty series is widely chosen by machine builders for its ideal balance of cable payload capacity, structural rigidity, and economical pricing. Precision-molded from 100% virgin PA66 engineering nylon—without recycled fillers or low-grade additives—it delivers exceptional tensile strength, low friction, and long-term fatigue resistance under continuous reciprocating movement.

Featuring a lightweight open-bridge architecture, this medium-duty plastic drag chain reduces moving mass on equipment gantries while allowing quick cable insertion, visual inspection, and easy routine maintenance without dismantling the entire chain. The open crossbars promote efficient airflow around power leads, servo feedback wires, and pneumatic lines, preventing thermal degradation. For harsh machining environments where flying coolants, chips, or dust pose a hazard, consider our fully sealed 35 series enclosed drag chain range.
