37mm Inner Height Series

37 Series Side-Open Multi-Axis Cable Carriers

Managing and protecting high-flex power cables, encoder wires, and pneumatic hoses on 3D articulated automation requires specialized, high-durability guidance systems. The 37 Series multi-axis cable carrier is engineered specifically for multidirectional spatial motion across Axes 1 through 6 on industrial robot arms. Featuring a compact 37mm internal clearance and an advanced circular tubular design, this high-performance 37 Series 3D robotic cable drag chain delivers reliable protection against rotational strain, high-speed twisting, and dynamic friction in demanding factory environments.

Innovative Side-Open Slotted Architecture for Rapid Maintenance

Traditional fully enclosed robotic energy chains or standard rectangular drag chains often require technicians to detach heavy industrial plugs and hardwire connectors during installation or line replacement. The 37 Series multi-axis cable carrier eliminates this operational bottleneck through its innovative staggered side-open slotted profile:

Fast Press-In Cable Insertion

Designed with flexible, offset side slits along the circular chain links, internal cables and pneumatic hoses can be pressed directly into the carrier cavity by hand. Pre-assembled cables with bulky connectors, strain-relief fittings, or multi-pin plugs pass straight into the carrier without electrical pin disassembly.

Round Tubular Geometry for 360° Spatial Motion

The smooth circular outer profile minimizes external resistance against robotic arm brackets, dress pack covers, and adjacent equipment. This round geometry allows continuous multidirectional bending and torsional deflection (±10° to ±15° per link) while eliminating sharp corners that cause premature sheath wear.

Engineering Performance & Material Specifications

Constructed from high-tensile, fiber-reinforced Polyamide (PA66), our 37 Series side-open 3D cable tracks withstand aggressive acceleration, ambient vibration, and chemical exposure in industrial workcells. Review the baseline technical parameters below:

Primary Applications in Industrial Robotics & Automation

By combining high torsional freedom with rapid cable fitting, our 37 Series round multi-axis energy chains are widely adopted across modern automated manufacturing sectors:

6-Axis Industrial Robots: Provides streamlined dress pack line guidance along Axes 3 to 6 on Fanuc, KUKA, ABB, Yaskawa, and Kawasaki articulated arms.
High-Speed Palletizing & Material Handling: Protects pneumatic gripper lines and sensor wiring during fast, repetitive pick-and-place rotational cycles.
Collaborative Robots (Cobots): Lightweight, non-abrasive circular cable routing that prevents snagging on safety covers and cobot joints.
Automated Welding & Cutting Cells: Shields secondary control wiring and gas supply lines operating within space-constrained robotic work envelopes.

Installation & Cable Fitting Recommendations

To maximize operational lifespan and prevent thermal or mechanical binding inside the 37 Series multi-axis cable carrier, maintain a total internal fill ratio below 80%. Ensure that individual cable diameters do not exceed 30mm, leaving adequate rotational clearance inside the 37mm inner cavity. Always integrate strain-relief mounting brackets at both moving and fixed end connection points to isolate tensile forces from internal electrical terminals.
