7 × 7mm Closed Nylon Cable Drag Chain – 1m Length

Nylon cable drag chain for guiding and protecting flexible wiring during repeated movement in 3D printers, CNC machines, robots and automation equipment. This compact version has a nominal internal cross-section of 7 × 7mm and an approximate length of 1 metre.

Its small size is suitable for installations with only a few conductors and limited available space. The closed links keep the wiring inside the chain; cables normally need to be fed through from one end.

Main features

• Material: black nylon.
• Approximate length: 1 metre.
• Nominal internal cross-section: 7 × 7mm.
• Construction: closed links.
• Guided movement in one plane.
• Good wear resistance.
• Integrated mounting ends, as shown in the product images.
• Mounting hardware not included.

Typical applications

• Wiring for moving 3D-printer axes and toolheads.
• Sensors, endstops and small fans.
• CNC machines, engravers and laser cutters.
• Small-format robotics and automation.
• Guiding conductors subjected to repeated movement.

Checking compatibility

The 7 × 7mm measurement refers to the nominal internal space, not the outside dimensions. Before selection, check the total cable-bundle diameter and particularly the size of any connectors that must pass through the closed links.

Cables should not completely fill the internal section. Leave enough room for them to move slightly during bending without rubbing, compression or strain on their connectors.

Also check:

• The complete required travel.
• Available space when the chain is curved.
• Position and geometry of the mounting points.
• Minimum bend radius of every cable.
• Whether the cables are rated for repeated flexing.

Installation recommendations

• Feed the cables through without twisting them before securing the ends.
• Arrange them without crossings or knots.
• Leave slight slack and prevent tension.
• Mount both ends so that the chain remains aligned.
• Move the axis manually through its full travel before powering the motors.
• Make sure that no cable exceeds its minimum bend radius.
• Provide strain relief at both ends.

The chain controls the cable path, but it does not turn ordinary wire into continuous-flex cable. Use motion-rated conductors in high-cycle applications.
