Overview of Corrugated Tube Dust-Free Drag Chain

GuangRou Corrugated Tube delivers precision cable management for controlled environments where contamination control is critical. Engineered with smooth inner surfaces and flexible construction, this tube protects sensitive cables while maintaining cleanroom compliance standards. The corrugated design provides structural integrity and kink resistance, ensuring reliable performance in pharmaceutical, semiconductor, and medical device manufacturing facilities. Easy to install and route through tight spaces, it minimizes cable exposure and maintains system cleanliness. Ideal for applications requiring both protection and environmental integrity.

Introduction to Corrugated Tube Dust-Free Drag Chain

Guangrou Corrugated Tube Dust-Free Drag Chain (GRS Series) FAQ

1. What is the opening and closing structure of the GRS series corrugated tube dust-free drag chain?

The GRS series uses a claw-type reverse zipper structure, where the side of the sheath can be opened and closed using a special locking clip. The advantage of this design is that it allows quick access to the interior for inspection, cable routing, and maintenance without disconnecting cable connectors. It is more efficient than traditional drag chains that require link-by-link disassembly. Internal spacers are used to separate cables, reducing friction and tangling.

3. What application scenarios are suitable for the GRS series corrugated tube dust-free drag chain?

The GRS series is suitable for short-to-medium travel applications with limited space and cleanliness requirements. Common applications include:

• Semiconductor inspection equipment
• Medical devices and cleanroom equipment
• Precision automation equipment
• Small assembly and handling systems
• Cleanroom applications where installation and maintenance convenience is important

Its zipper-style open design makes it particularly suitable for applications requiring frequent inspection or quick cable replacement.

4. What are the key installation considerations for the GRS series?

When installing the GRS series corrugated tube dust-free drag chain, the following points should be noted:

1. Both upper and lower covers must be tightened simultaneously. Tightening only one side may cause the covers to crack during operation.
2. Ensure adequate fixed length. A minimum straight fixed section of 100 mm must be maintained from the clamp outlet to the start of the bend.
3. Reserve sufficient safety clearance. The drag chain must not interfere with any machine structure at its maximum travel position.
4. Distribute spacers evenly. For models with internal spacers, the spacers must be evenly distributed and securely locked into the slots. Concentrating them at one end may cause cable compression, wear, or noise.
5. Mount the moving end at the end of the travel path. This prevents the drag chain from tangling with cables or other components.

5. What is the difference between the GRS series and the GRC open-style series?

Comparison Item	GRS Corrugated Tube Series	GRC Open-Style Series
Opening Method	Claw-type reverse zipper, secured with special locking clips	Side snap-open design
Sheath Structure	Corrugated tube outer shell, higher flexibility	Flat pod structure, slightly higher rigidity
Internal Separation	Uses spacers to isolate cables	Independent tube compartments
Suitable Applications	Compact spaces requiring good flexibility, short travel	Applications requiring frequent cable changes, larger cable connectors
Material	PTFE + TPU	PTFE / E-PTFE
Cleanliness Class	ISO Class 1	ISO Class 1

Both series offer easy-access designs for maintenance. The main difference lies in the sheath structure and opening mechanism. The choice between them depends on the available installation space and maintenance preferences.
