Question 1

Are you a trading company or manufacturer?

Accepted Answer

We are a factory.

Question 2

How do I choose the right protective cover/drag chain model?

Accepted Answer

The selection mainly depends on the following parameters: Stroke length (protective cover expansion ratio/drag chain bending radius), Load type (number of cables, oil pipe pressure), Environmental requirements (temperature resistance, water proof, corrosion resistance level). We provide a free selection tool and one-on-one guidance from our engineers.

Question 3

Which is better, a nylon bellows cover or a stainless steel bellows cover?

Accepted Answer

It depends on the application: Nylon covers are lightweight, corrosion-resistant, and cost-effective, suitable for general industrial environments. Stainless steel covers are high-temperature and impact-resistant, suitable for heavy-load, highly corrosive environments (such as electroplating and chemical processing).

Question 4

Do you support non-standard customization? How long is the turnaround time?

Accepted Answer

We support full customization, including: Dimensions (extra-long/special-shaped cross-sections), Material (anti-static, food-grade, etc.), Mounting method (magnetic, quick-release, etc.). Standard customization timeframe is 7-15 days, and expedited orders can be shortened to 3-5 days.

Question 5

What should I do if the bellows cover makes a grinding noise after installation?

Accepted Answer

Possible causes and solutions: Insufficient lubrication: Use a special silicone-based lubricant. Assembly deviation: Contact our technical support for remote debugging.

Question 6

Cables in the drag chain are frequently worn. How can I resolve this?

Accepted Answer

Recommendations: Check for overloading (number of cables exceeds the drag chain capacity), Add separators to prevent cable friction, Use highly flexible cables for use with the product.

Question 7

How often should the bellow cover be replaced?

Accepted Answer

It depends on the usage environment. Generally: Nylon cover: 3-5 years (without mechanical damage), Stainless steel cover: 5-8 years. We offer a free lifespan assessment service.

Question 8

Is it in stock? What is the delivery time?

Accepted Answer

Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.

Question 9

How do I resolve product quality issues?

Accepted Answer

Take photos/videos of the problem area and send them to our customer service email address. We will provide a solution within 24 hours (replacement/return/on-site service).
