The plastic cable drag chain is a PA66 engineering-plastic carrier designed to guide and protect moving cables, oil hoses, pneumatic tubes and water lines during repeated machine travel. Its articulated chain links follow a controlled bending path, helping reduce cable tangling, pulling and direct abrasion.

LONGQIAO supplies compact, reinforced, openable, semi-closed and fully enclosed configurations across 10–100 Series. Available catalogue dimensions cover internal heights from 10 to 100 mm, internal widths from 10 to 400 mm and bending radii from R18 to R400. The range is suitable for CNC machines, laser equipment, woodworking machinery, automation lines and other reciprocating-motion systems.
