CNC Cable Drag Chain 45x250 – Bridge Open Type

Product Overview

The 45x250 bridge open type cnc cable drag chain is one of the premier middle-duty models in our 45mm series, precision-molded from 30% glass-fiber reinforced PA66 nylon. Featuring a 45mm inner height and an extra-wide 250mm inner clearance, this high-capacity cnc cable drag chain accommodates up to 18–22 standard power cables, hydraulic hoses, or pneumatic lines. It is the perfect dynamic cable protection solution for large CNC machining centers, gantry milling equipment, heavy-duty lathes, and industrial laser cutting tables.

Compared to narrower 45x150 models, the 45x250 cnc cable drag chain provides 100mm of additional internal width. This extra space allows for clean separation of multi-layer cable bundles, significantly reduces frictional wear between lines, enhances internal airflow for cooling, and leaves generous room for future machine upgrades.

Technical Specifications

Injection Molding Precision Manufacturing

Our production facility uses high-tonnage industrial injection molding machines to craft every link of the 45x250 cnc cable drag chain. By utilizing high-grade 30% glass-fiber PA66 raw materials, we ensure strict dimensional accuracy, high tensile strength, and uniform structural density across all chain components.

Quality Control & Load Bearing Test

To ensure long-lasting dynamic movement on heavy machinery, each 45x250 cnc cable drag chain batch undergoes rigorous toughness and load capacity evaluations. The glass-fiber reinforcement prevents structural sagging on long unsupported travels, enduring high impact and flex cycles without fracture or deformation.

Customization Options

We offer versatile customization options for the 45x250 cnc cable drag chain to suit specific equipment layouts:

• Vertical Inner Separators: Adjustable dividers to isolate high-voltage power cables from delicate signal lines and minimize friction.
• Side Fiber Optic Clips: External mounting clips to route optical fibers separately and protect them from crushing.
• Steel Mounting End Brackets: High-strength steel brackets available to replace plastic brackets for extreme heavy-duty mounting needs.
• Custom Color Coding: Standard black body with yellow pins, or full custom RAL colors (MOQ = 1,000m).
• Brand Logo Marking: Custom laser marking or molded logos on link side plates.

Applications

The 45x250 cnc cable drag chain is specifically built for large-scale industrial machinery requiring high cable payloads and long travel distances. It supports unsupported travel spans up to 5 meters, and can be used in gliding configurations with guide troughs for longer machine strokes. Typical uses include gantry milling centers, heavy CNC lathes, large laser cutters, and robotic transfer units.

Professional Packaging & Shipping

All finished 45x250 cnc cable drag chain orders are packed into reinforced export cartons, stacked onto pallets, and bound securely with stretch film and heavy-duty strapping to guarantee pristine condition upon arrival at your workshop.
