Cable Drag Chain 55x200 Snap Open Bridge Type Cable Carrier for CNC Machine Tools & Industrial Automation

Specifically engineered for high-load applications, long travel distances, and high-dynamic motion, our heavy-duty cable drag chain 55x200 (55mm inner height x 200mm inner width) snap open bridge type cable carrier provides extra-wide interior clearance. It accommodates complex multi-conduit bundles, including thick servo power cables, control lines, pneumatic tubes, and high-pressure hydraulic hoses. Molded in an all-black aesthetic finish from high-strength 30% glass-fiber reinforced PA66 nylon (PA66 + 30% GF), this robust energy chain guarantees exceptional wear resistance, impact strength, flame retardancy (UL94 V-0), and smooth, low-noise operation for 24/7 industrial environments.

The innovative snap-open bridge structure allows crossbars to be unlatched quickly from either side using a standard flathead screwdriver, significantly simplifying cable laying, inspection, and retrofitting—even in tight machine envelopes. With high chemical resistance, thermal stability (-40°C to +130°C), and anti-aging properties, the 55x200 series is the ideal cable protection system for large gantry machining centers, heavy CNC lathes, automated welding lines, industrial robots, and mobile material stackers.

Virgin PA66 resin compounded with 30% high-tensile glass fibers, providing superior rigidity, wear resistance, and heat tolerance for cable drag chain 55x200 manufacturing.

Technical Specifications

Heavy-Duty Manufacturing & Quality Control

Every unit of our cable drag chain 55x200 series is manufactured in our modern injection molding facility under rigorous ISO quality management systems. Utilizing high-tonnage precision molding equipment and modified PA66 engineering resins, each link undergoes stringent dimensional inspection and dynamic fatigue testing to ensure zero sagging and minimal wear during continuous long-travel operations.

Our large-scale automated injection molding workshop equipped with heavy machinery for high-capacity drag chain manufacturing.

Primary Industrial Applications

• CNC & Metalworking Machine Tools: Gantry machining centers, heavy-duty CNC lathes, vertical/horizontal boring mills, floor-type machining tools, and CNC punch presses.
• Laser & Cutting Equipment: Fiber laser cutting machines, plasma cutting systems, flame cutters, waterjet cutting gantries, and stone/glass CNC cutting machinery.
• Automated Production Lines & Robotics: Automotive robotic welding/coating lines, 3C electronic packaging, ASRS warehouse stacker cranes, logistics sorting systems, and 6-axis/7-axis/truss manipulators.
• Large Woodworking & Stone Machinery: Heavy CNC panel saws, automatic edge banders, marble/granite bridge saws, and stone CNC machining gantries.
• Heavy Machinery & Renewable Energy: Injection molding machines, die-casting equipment, construction machinery, wind turbine pitch equipment, port cranes, and photovoltaic module production lines.

55mm Series Dimensions & Inner Height 50mm Cross-Reference

Our 55mm inner height series is available in standard inner widths to match various conduit capacities:

• 55 x 75 mm: Ideal for standard CNC tools holding 4 to 10 standard cables.
• 55 x 100 mm: The most popular 'golden size' for general automation and robotics, holding 6 to 15 standard cables.
• 55 x 125 mm: Upgraded choice for CNC lathes, automated lines, and light cranes, holding 8 to 20 cables.
• 55 x 150 mm: Wide-body carrier for port machinery, heavy gantries, and complex multi-hose routing (10 to 25+ cables).
• 55 x 200 mm: Extra-wide heavy-duty carrier for large gantry systems, heavy manipulators, and extensive industrial hose bundles.

Selection Note for Inner Height 50mm Series (e.g., 50x150mm, 50x120mm, 125x50mm): If your equipment requires a non-standard 50mm inner height cable carrier, we strongly recommend upgrading to our 55mm inner height series (such as 55x150mm or 55x200mm). The additional 5mm height clearance provides superior flexibility, reduces cable friction, and accommodates thicker cable connectors effortlessly. Alternatively, if your installation space is strictly limited in height and cable outer diameter is under 40mm, you may also refer to our 45mm inner height series (such as 45x150mm).

Selection Guide: Bridge Type vs. Fully Enclosed Drag Chains

Snap-Open Bridge Nylon Drag Chain (55x200): Best suited for dry, clean, or dust-controlled workshop environments requiring optimal heat dissipation, fast visual cable inspection, and easy line maintenance.

Fully Enclosed Nylon Cable Chain: Essential for severe industrial environments filled with hot metallic chips, grinding swarf, dust, and aggressive cutting fluids, offering 360-degree sealed cable protection. For heavy machining applications, explore our heavy-duty cable drag chain 55x150 enclosed type.
