25 Series Double Bending Radius Cable Carrier (H25)
Engineered for non-linear motion trajectories and tight operational spaces, the 25 Series Double Bending Radius Cable Carrier (H25) provides exceptional bi-directional flexibility and robust dynamic protection for flexible cables and hoses. Unlike traditional single-direction drag chains, this series features an innovative dual-directional bending mechanism, allowing seamless "S-shape" movements along opposing axes. It is the premier guidance solution for modern multi-joint robotic arms, medical articulated scanners, dual-axis gantries, and compact automated machinery.
Key Engineering Features & Technical Advantages
- Precision Bi-Directional Motion (R55 Bending Radius): Specially designed with an R55 mm reverse bending radius, enabling smooth forward and backward flex patterns without compromising structural integrity or cable wear limits.
- Optimized Structural Dynamics: Standardized with a precise 46 mm pitch requiring exactly 22 links per meter, delivering quiet operation, low friction, and long-service-life performance during high-speed reciprocating movement.
- Bridge Openable Architecture: Features a user-friendly bridge openable principle across both inner and outer radii, allowing rapid cable installation, effortless line inspection, and hassle-free maintenance without disconnecting whole assemblies.
- High Capacity Inner Clearance: Accommodates a maximum external cable/hose diameter of up to 22.5 mm, providing optimal internal space utilization and efficient heat dissipation for power, control, and pneumatic lines.
- Versatile Material Options (Standard PA66 & Glass Fiber Reinforced PA66): Available in both standard unreinforced Polyamide (PA66) for cost-effective standard operations, and high-performance Glass Fiber Reinforced Polyamide (PA66+GF) for demanding environments requiring extreme tensile strength, higher load capacity, and enhanced fatigue resistance under high-speed acceleration.
