55mm Inner Height Series

CNC Cable Carrier 55mm Series – Bridge Open Type

Heavy-Duty Cable Guidance for Demanding CNC Systems

In high-capacity industrial automation and large-scale manufacturing, selecting a high-rigidity cnc cable carrier system is essential to guard heavy electrical bundles, high-pressure hydraulic lines, and pneumatic supply hoses. The 55mm series cnc cable carrier (bridge open type) is built as a premier heavy-duty cable management solution. Sitting within our heavy-duty series tier (55mm and 65mm inner height models), it bridges the gap before transitioning into ultra-capacity extra heavy-duty systems (80mm and 100mm models).

Featuring a generous **55mm internal height** and customizable **widths ranging from 50mm to 300mm**, this robust cnc cable carrier accommodates large cables and flexible hoses up to 50mm outer diameter. It easily organizes 20 to 25+ cables simultaneously, making it ideal for heavy gantry machining centers, long-bed lathes, large laser cutting platforms, and high-load robotic transfer tracks.

Material Performance: 30% Glass-Fiber Reinforced PA66

Standard plastic drag chains often deform or sag when carrying dense cable bundles across long travels. Our heavy-duty cnc cable carrier series is injection-molded from premium **PA66 nylon compound reinforced with 30% glass fiber**, delivering distinct mechanical superiorities over basic plastic alternatives:

Maximum Load Rigidity: Glass-fiber reinforcement dramatically boosts structural tensile strength, supporting heavy dynamic payloads with minimal flex over extended unsupported spans.
Long Dynamic Lifespan: High fatigue resistance guarantees over 10 million flex cycles under continuous, high-speed travel conditions.
Superior Wear & Abrasion Resistance: High surface hardness minimizes friction wear at chain link joint pins, reducing mechanical play over years of operation.
Wide Thermal Range: Performs reliably from -40°C to +130°C, resisting cold-room brittleness and high-heat deformation near hot cutting zones.
Fluid & Flame Resistance: Highly resistant to cutting coolants, synthetic lubricants, and industrial oils, with a UL94 V-2 flame retardant safety rating.

Open Bridge Architecture Advantages

The open bridge frame incorporates hinged, snap-open crossbars on both top and bottom sides, easily opened using a standard flathead screwdriver:

Rapid Cable Installation: Lay complex, pre-terminated cable harnesses straight into the track without pulling them through link by link.
Effective Air Cooling: Maximizes ambient airflow around heavy-duty power lines, dissipating thermal buildup during continuous high-flex movement.
Lower Motor Drive Load: Weighs roughly one-third of traditional steel carriers, reducing overall deadweight and allowing faster axis acceleration rates.
