Drag chain cables in CNC machines and robotic arms fail too often — cracking, fraying, signal loss — forcing unplanned downtime and costly replacements. The root cause? Standard PVC jackets can’t handle millions of flex cycles. Abrasion from chips, coolant, and debris eats through insulation fast.This imported 12-core drag chain cable is built for exactly that. 0.25mm² fine-strand signal conductors carry control signals reliably through constant bending. The outer jacket is flex-grade PUR polyurethane — tough against abrasion, oil, coolant, and UV. It moves with your machine, not against it.Core Specifications

Why This Cable Holds Up Where Others Don’t— Million-cycle flex life. PUR polyurethane resists micro-cracking under repeated bending. Tested beyond 5 million cycles at rated bend radius — ideal for high-speed reciprocating axes on machining centers.— Abrasion and chip resistance. The PUR jacket surface handles metal swarf, coolant splash, and dust without thinning. No premature jacket failure in chip-heavy milling or stamping environments.— Fine-strand conductors stay intact. 0.25mm² Class 5 flex conductors resist work-hardening and breakage. Signal continuity holds even after thousands of directional changes in energy chains.— Oil and coolant compatible. PUR does not swell or degrade in contact with standard cutting fluids, hydraulic oil, or lubricants. No jacket softening that leads to conductor exposure.Typical ApplicationsCNC machine tools, robotic welding cells, automated assembly lines, pick-and-place systems, packaging machinery, laser cutting machines, gantry systems, and any moving carriage requiring multi-core signal transmission inside cable carriers.** sourcing, Customization & Support**We supply this drag chain cable with flexible MOQ for prototyping and volume runs.
