Flexible Cable Conduits & Tubing

Flexible Enclosed Metal Drag Chains & Cable Carriers

Discover next-generation heavy-duty cable protection with our premium flexible enclosed metal drag chains. Specially engineered to bridge the performance gap between heavy steel cable carriers and lightweight plastic drag chains, these advanced cable enclosures offer unmatched structural shielding combined with superior dynamic flexibility. Designed to protect power cables, hydraulic lines, coolant tubes, and sensor wires from the harshest industrial environments, they represent the ultimate cost-effective solution for modern high-precision CNC machinery and automated equipment.

Why Choose Advanced Flexible Enclosed Metal Cable Carriers?

Traditional steel cable carriers are exceptionally rugged but can be heavy, rigid, and expensive. On the other hand, standard nylon drag chains often fail prematurely when exposed to sharp, red-hot flying metal chips or intense cutting fluid spray. Our fully enclosed metal drag chain systems eliminate these limitations by combining a toughened steel or stainless steel protective outer shield with flexible internal architecture:

100% Chip & Coolant Barrier: The fully interlocking sealed structure prevents red-hot metal swarf, abrasive dust, high-pressure cutting fluids, and oil mist from penetrating the interior.
Outperforms All-Steel Drag Chains: Delivers higher bending flexibility, significantly lighter deadweight, lower operational noise, and superior budget efficiency without sacrificing strength.
Outperforms Plastic Drag Chains: Provides vastly superior impact resistance, heat tolerance, and chemical stability, extending overall cable service life in demanding industrial settings.

Series Overview & Comparison: DGT vs. JR Series

To accommodate varying travel distances, mounting envelopes, and cable capacities, we supply two distinct enclosed metal conduit architectures:

Model	DGT Series	JR Series
Series Name	Flexible conduit cable carrier	Closed metal drag chain / hose
Protection Type	Fully enclosed	Fully enclosed
Material Structure	Stainless steel SUS430 + PA (Nylon) lining	Steel & galvanized steel spiral band
Cross Section Shape	Square	Rectangular
Inner Size (H×W mm)	25x45, 38x73, 45x90, 52x102, 60x120, 65x150, 72x162	20x30, 25x50, 35x60, 38x73, 40x80, 50x90, 52x102, 60x120, 60x130, 72x162
Cross-Reference Models	Conduflex cable carrier equivalent	Tubiflex cable carrier equivalent
Core Advantages	1. Closed shield prevents entry of burning debris and coolant. 2. Lighter weight, higher flexibility, and better budget efficiency than traditional all-steel chains. 3. Exceptional durability, wear resistance, and service life compared to standard plastic drag chains.
Main Applications	Heavy-duty CNC machine tools, CNC lathes, gun drilling machines, CNC deep hole drilling machines, and automated industrial sliding axes.

Precision Structural Design & Manufacturing Processes

Our enclosed metal cable carriers are manufactured through specialized metalworking procedures to guarantee structural integrity and smooth dynamic operation:

1. DGT Armored Link Assembly Process

The DGT series incorporates carburized heat-treated steel side pins and precision-stamped SUS430 stainless steel C-profile cover plates. These interlocking armor plates slide seamlessly over an internal wear-resistant polyamide (nylon) profile, guiding cables along a controlled bending radius while deflecting flying metal debris.

2. JR Spiral Winding & Lock-Seam Fabrication

The JR rectangular metal hose is manufactured using continuous cold-roll forming and spiral interlock winding of high-grade galvanized steel or stainless steel strip. Featuring a double-groove interlock joint profile, it is internally reinforced with a spring steel flat wire skeleton to prevent crushing, twisting, or collapsing under continuous dynamic flexing.

3. Smooth Inner Passage & Precision Mounting Flanges

Both design architectures feature a burr-free interior surface that minimizes cable jacket friction. They are completed with die-cast aluminum or heavy-duty steel end connection brackets (available in square, octagonal, or custom flange patterns) to ensure effortless mounting and direct drop-in replacement on modern machine tools.

Industrial Applications & Custom Direct OEM Supply

Our flexible enclosed metal drag chains are widely deployed across global manufacturing sectors, including heavy-duty CNC turning centers, gantry machining equipment, gun drilling machinery, deep hole drilling tools, and automated steel mill processing lines. Whether you are seeking a direct replacement for international brands like Conduflex or Tubiflex, or require custom end-bracket mounting flanges, custom inner dimensions, or specialized stainless steel grades (SUS304/SUS316), we deliver factory-direct engineering and OEM solutions tailored to your technical specifications.
