20mm Bridge Nylon Drag Chain – High-Performance Plastic Drag Chain Series

Product Overview

Our 20mm bridge series is a versatile, heavy-duty plastic drag chain engineered to protect and route cables, pneumatic hoses, and control lines in dynamic automated systems. Precision-molded from premium PA66 (Nylon 66) engineering polymer, this robust plastic drag chain delivers superior mechanical strength, excellent wear resistance, and long-term fatigue durability. Featuring a self-lubricating joint structure and a wide operating temperature tolerance (-40°C to +120°C), it ensures whisper-quiet, low-vibration operation during continuous reciprocating movement.

The open bridge structure allows for efficient heat dissipation and clear visual inspection of internal lines, preventing dust buildup while extending cable flex life. For applications requiring complete protection against flying swarf or debris, view our 20mm Enclosed Nylon Drag Chain.

Key Advantages & Modular Features

• High-Toughness PA66 Construction: Molded from virgin PA66 polymer to prevent link cracking, withstand chemical exposure, and endure high-speed travel.
• Flexible Bending Radii Options: Available in 7 radius variants (R55 to R200) to meet tight enclosure allowances or generous cable bend requirements.
• Custom Interior Separation: Supports vertical separators and horizontal shelves to keep power lines, signal wiring, and pneumatic hoses organized and strain-free.
• Heavy-Duty Mounting Connectors: Fitted with steel or reinforced nylon end-brackets to ensure rigid anchor points at both fixed and moving ends.

Industrial Target Applications

The 20mm series plastic drag chain is designed for high-cycle industrial automation equipment, including:

1. CNC Router & Milling Tools: Protects servo motor power cables and feedback lines along X/Y/Z motion axes.
2. Robotics & Automated Assembly Lines: Guides pneumatic tubes and sensor lines in high-speed pick-and-place systems.
3. Packaging & Material Handling Equipment: Delivers reliable cable protection in continuous multi-axis sorting machinery.
4. Semiconductor & Medical Machinery: Ensures clean, low-particulate, and whisper-quiet operation in controlled environments.
