25x75 CNC Drag Chain R55 - Bridge Open Type Reinforced Nylon Cable Carrier

Product Overview

The 25x75 bridge open type CNC drag chain R55 is high-precision cable track molded from premium 30% glass-fiber reinforced PA66 engineering nylon (PA66 + 30% GF). Featuring a compact 25mm inner height, a 75mm inner width, and a tight 55mm bending radius (R55), this model safely houses up to 8 standard power cables, feedback leads, or pneumatic hoses. The tight R55 curve allows smooth reciprocating travel inside narrow machine housings, while the open bridge design ensures rapid thermal dissipation and easy snap-open cable access without disassembling the track assembly.

Technical Specifications

Injection Molding Workshop & Raw Material Advantages

Every link of our 25x75 CNC drag chain R55 is manufactured in our automated injection workshop using 30% glass-fiber reinforced PA66 nylon. Incorporating glass fibers into the nylon matrix delivers substantial mechanical performance advantages over unfilled plastics:

• Superior Tensile Strength & Rigidity: Holds heavy conductor loads over extended unsupported spans without drooping or flexing sideways.
• High-Speed Flexural Fatigue Resistance: Withstands over 10 million continuous high-speed reciprocating stroke cycles without joint degradation.
• Compact R55 Bending Clearance: The R55 radius enables short loop heights, allowing smooth operation inside compact machine enclosures.
• Enhanced Thermal & Dimensional Stability: Operates reliably at temperatures up to +130°C and maintains tight pitch tolerances even in humid environments.
• Chemical & Wear Endurance: Resists oil mist, synthetic cutting lubricants, greases, and mild washdowns.

Precision Automated Link Production

Molded using high-precision multi-cavity tooling, each link maintains an exact 46mm pitch distance to minimize hinge friction and ensure quiet operation below 60dB. The open bridge design features snap-open crossbars along the inner radius, allowing operators to lay cables directly into the carrier without tedious threading. Internal vertical separators can also be installed to prevent cable crossover and jacket abrasion during rapid acceleration.

Industrial Equipment Applications

The 25x75 CNC drag chain R55 is widely deployed across compact automated equipment where installation space is tight and high flexural durability is essential:

• CNC Milling & Lathe Turning Centers: Guiding tool changer wiring and coolant lines on compact axes.
• Laser Cutting & Engraving Equipment: High-speed gantry cable guidance with minimal loop height.
• CNC Wood Routers & Stone Carving Gantries: Reliable dust-resistant cable support over long stroke paths.
• Pick-and-Place Robotics: Dynamic power and signal line protection on multi-axis automated lines.

Export Packaging & Factory Stocking

As a direct factory supplier, we maintain large stock reserves of assembled 25x75 CNC drag chain R55 units and component links to ensure quick order processing and worldwide delivery. All orders are packed in heavy-duty corrugated export cartons and reinforced with poly strapping for safe international transit.
