Component Specifications

Definition
A link is a standardized, interlocking component that constitutes the building block of an internal cable carrier (also known as an energy chain or drag chain). Multiple links are assembled in series to create a flexible, enclosed conduit that guides, protects, and organizes cables, hoses, and tubing in automated machinery and industrial equipment. It is designed to withstand repeated bending cycles, mechanical stress, and environmental factors while preventing cable abrasion, entanglement, and failure.
Working Principle
Links operate on a modular interlocking principle, where each link features male and female connectors (e.g., snap-fit, hinge, or pin mechanisms) that allow it to securely attach to adjacent links, forming a continuous chain. This assembly creates a segmented, flexible track that bends along a defined radius as the machine moves, enabling cables and hoses to travel safely without overextension, twisting, or wear. The links' design distributes mechanical loads evenly and maintains cable separation to prevent interference.
Materials
Typically engineered thermoplastics (e.g., polyamide/PA, polypropylene/PP, or polyoxymethylene/POM) for lightweight, corrosion-resistant, and low-friction properties; may include reinforced variants (glass-filled) for higher strength. Metal links (e.g., stainless steel, aluminum) are used in heavy-duty or high-temperature applications.
Technical Parameters
  • Width 10 mm to 200 mm (internal width for cables)
  • Height 15 mm to 150 mm
  • Length Varies by model (e.g., 25 mm to 100 mm per link)
  • Max Speed Up to 10 m/s
  • Load Capacity 1 kg/m to 50 kg/m (dynamic)
  • Bending Radius 50 mm to 500 mm (depends on link design)
  • Max Acceleration Up to 50 m/s²
  • Temperature Range -40°C to +120°C (plastic), up to +500°C (metal)
Standards
ISO 12098, DIN 55142

Engineering Analysis

Risks & Mitigation
  • Link fracture under excessive load
  • Cable abrasion from improper installation
  • Chain jamming due to misalignment
  • Reduced flexibility from wear or contamination
  • Thermal degradation in high-temperature environments
FMEA Triads
Trigger: Overloading beyond specified capacity
Failure: Link cracking or breaking, leading to cable exposure and machine stoppage
Mitigation: Design with safety margins, use load calculations, and select reinforced materials.
Trigger: Misalignment during installation
Failure: Uneven wear, increased friction, and premature link failure
Mitigation: Follow manufacturer guidelines, ensure proper alignment tools, and conduct pre-operation checks.
Trigger: Exposure to harsh chemicals or extreme temperatures
Failure: Material degradation (e.g., brittleness, swelling), reducing link integrity
Mitigation: Use chemically resistant or high-temperature materials (e.g., stainless steel, specialized plastics).

Frequently Asked Questions

How do I select the right link for my application?

Consider cable/hose dimensions, bending radius, speed, acceleration, environmental conditions (temperature, chemicals), and load capacity. Match link material (plastic vs. metal) to mechanical and thermal demands.

Can links be replaced individually if damaged?

Yes, most links are designed for easy replacement without disassembling the entire carrier, minimizing downtime. Ensure compatibility with the existing chain model.

What maintenance do cable carrier links require?

Regular inspection for wear, cracks, or debris; lubrication of hinges/pins if specified; and cleaning to prevent contamination. No routine maintenance is needed for sealed designs.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
