25mm Inner Height Series

25mm Series CNC Drag Chain - Bridge Open Type Cable Carrier, 30% GF Nylon

Series Overview

The 25mm series is the most compact option in our CNC drag chain bridge open type lineup. With 25mm inner height, it is specifically designed for small to medium cable bundles (up to 23mm OD per cable) on light to medium-duty CNC equipment.

⌈What makes this series different from other sizes? The 25mm series is optimized for tighter machine spaces where larger 35mm or 45mm cnc cable chains simply don't fit. It offers the smallest bend radius options (from R55), making it ideal for compact CNC designs.

Also referred to as 25mm cable carrier, 25mm cable chain, or 25mm cable track.

When to Choose 25mm Series

The 25mm series is the right choice when your CNC machine has limited installation space and cannot accommodate larger 35mm or 45mm drag chains. It is ideally suited for small to medium cable bundles — typically up to 6 to 8 standard cables or hoses, depending on the width you select. This series works best on light to medium-duty CNC equipment such as compact machining centers, small lathes, routers, engravers, and pick-and-place machines. The open bridge design also makes it a great fit for applications requiring frequent cable access, as the snap-open links allow quick changes without disassembling the chain.

Not recommended for: heavy cable bundles, cables over 23mm outer diameter, or heavy-duty machining environments with large chip loads and aggressive coolant flow. For those applications, consider our 35mm or 45mm series instead

Material (30% GF + PA66)

Our 25mm series CNC drag chain is molded from 30% glass-fiber reinforced PA66 nylon. This material formulation delivers significantly higher strength and impact resistance compared to unfilled nylon, making it well-suited for the repeated flexing and mechanical stress encountered in CNC applications. The glass-fiber reinforcement also provides exceptional wear resistance, giving the chain a service life of over 10 million cycles under normal operating conditions.

The material maintains stable performance across a broad temperature range from -40°C to +130°C, ensuring reliable operation in both cold workshops and high-heat machining environments. It offers good resistance to oils, coolants, and mild acids or alkalis, so it won't swell or crack after prolonged exposure to industrial fluids commonly found in machine tool applications. The compound is UL94 V-2 rated for flame retardancy, adding a layer of safety protection. Additionally, the material's natural damping properties keep operating noise below 60dB, which is beneficial for precision machining environments where low noise is preferred.

Bridge Type Advantages

1.Fast heat dissipation – open-top design allows airflow

2.Easy installation – snap-open links, no threading required

3.Visual inspection – cables partially visible

4.Lightweight – 1/3 the weight of steel

Typical Applications for 25mm Series

The 25mm series cnc cable carrier is commonly used on smaller CNC equipment where space is limited and cable bundles are light to medium in size. Typical applications include compact CNC machining centers, small CNC lathes, CNC routers and engravers, pick-and-place machines, industrial-grade 3D printers, and smaller automation arms. For larger machines with heavier cable loads, we recommend moving up to the 35mm or 45mm series — the 25mm series is best suited for equipment with moderate cable requirements and tighter routing spaces
