Link: Height 15 mm to 150 mm, Max Speed Up to 10 m/s

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.

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.
