Plastic Drag Chain 38mm Snap-Open Bridge Series

Specially engineered for high-load CNC machinery and long-travel automation systems, this premium plastic drag chain series features a 38mm inner height combined with a snap-open bridge design. Manufactured from high-tensile PA66 polyamide reinforced with 30% glass fiber and specialized thermal additives, this heavy-duty plastic drag chain provides maximum structural rigidity, exceptional wear resistance, and long-term operating stability under demanding industrial conditions. Equipped with interlocking side plates, heavy-duty bolt fasteners, vibration-damping positioning inserts, and steel end brackets, this series ensures accurate cable tracking and quiet articulation across extended strokes.

Key Advantages & Structural Features

1. Snap-Open Crossbar Design for Rapid Access

The bridge-type architecture allows crossbars to be snapped open effortlessly along the inner or outer radius. Maintenance personnel can inspect, lay, or replace heavy power lines, fiber optic cables, and pneumatic hoses up to 34mm in diameter without disconnecting pre-wired assemblies, saving significant labor and reducing machine downtime.

2. Glass-Fiber Reinforced PA66 Polymer Body

Formulated from virgin PA66 nylon modified with 30% glass fiber, this plastic drag chain exhibits elevated tensile strength, superior impact resistance, and extended fatigue life. The material retains excellent mechanical properties across a wide temperature spectrum (-40°C to +130°C) and resists corrosion from industrial oils, lubricants, and chemical fluids.

3. Heavy-Duty Bolted Side Plates & Damping Inserts

Designed for long-travel strokes, each chain link features reinforced side plates held together with heavy-duty bolt fasteners to prevent joint separation during intense acceleration. Integrated positioning inserts absorb articulation vibrations, reducing operational noise and minimizing cable friction during continuous back-and-forth movement.

4. Heavy-Gauge Steel Mounting Connectors

Supplied with thick steel mounting brackets featuring standardized hole patterns, the plastic drag chain securely anchors to machine beds and moving gantries. This robust strain relief interface prevents stress concentrations from transferring directly to internal cables or hydraulic hoses.

Industrial Applications

The 38mm inner height snap-open plastic drag chain series is engineered for high-performance industrial equipment:

• CNC Gantry Routers & Milling Machines: Guides power leads, control wires, and cooling hoses along high-speed X/Y axes.
• Automated Material Handling & Stacker Systems: Delivers smooth cable management across long horizontal travel paths in automated warehousing.
• Laser, Plasma & Waterjet Cutting Machinery: Organizes multi-core control cables and gas supply lines cleanly and safely.
• Heavy Machinery & Woodworking Equipment: Keeps dynamic supply cables secure from accidental twisting or external abrasion.
