35mm Series CNC Drag Chain - Bridge Type

35mm Series Overview

The 35mm series CNC drag chain (bridge open type) is molded from 30% glass-fiber reinforced PA66 nylon for medium to heavy-duty CNC applications. With 35mm inner height, this series accommodates cables up to 32mm outer diameter and offers wider internal widths than the 25mm series — making it the ideal choice for CNC equipment with larger cable bundles. Available widths range from 50mm to 300mm. Also referred to as 35mm cable carrier, 35mm cable chain, or 35mm cable track.

When to Choose the 35mm Series

The 35mm series is the right choice when your 25mm series is too narrow for your cable bundle, but you don't quite need the bulk of a 45mm or 55mm cnc cable chain. It is ideally suited for medium to large cable bundles — typically up to 10 to 14 standard cables or hoses, depending on the width you select. This series works best on standard CNC equipment such as machining centers, milling machines, and larger lathes where moderate cable loads and standard routing spaces are common. The open bridge design also allows for fast heat dissipation and easy cable access, making it a versatile choice for a wide range of machine tool applications.

Not recommended for: very tight installation spaces that require a smaller 25mm series, or extremely heavy cable bundles that demand a 45mm or larger drag chain. For those applications, consider our 25mm or 45mm series instead.

Material - 30% Glass-Fiber Reinforced PA66

Our 35mm 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 economical 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.

R75, R100, and R150 are the most frequently requested options for the 35mm series. For widths above 125mm, R100 or larger is recommended to ensure proper cable clearance.

Bridge Type - Key Advantages

The bridge open type design means the  cnc cable chain is openable at the top and bottom with a screwdriver. This provides three key benefits: fast heat dissipation – airflow keeps cables cool during high-speed operation; easy installation –  links allow cables to be laid in without threading; visual inspection – cables remain partially visible, making it easy to spot wear or damage. Additionally, the bridge type is significantly lighter than steel drag chains — about one-third the weight — which reduces the load on your machine's drive system and allows for faster acceleration and deceleration.

Common Applications for 35mm Series

The 35mm series is commonly used on standard CNC equipment where cable bundles are medium to large in size. Typical applications include CNC machining centers, CNC milling machines, CNC lathes, CNC laser cutters, CNC routers, and industrial automation equipment. For larger machines with heavier cable loads, we recommend moving up to the 45mm or 55mm series — the 35mm series is best suited for equipment with moderate to large cable requirements and standard routing spaces.
