Preventive Maintenance Tips for Plastic Drag Chains

Plastic Drag Chains in Use

Plastic drag chains are an essential component of many industrial systems. They are used to guide and protect cables and hoses, ensuring that they remain safe and organized during the movement of machinery. However, like any other mechanical component, plastic drag chains require regular maintenance to ensure optimal performance and extend their lifespan. In this article, we will provide preventive maintenance tips for plastic drag chains that will help you keep your system running smoothly.

1. Inspect the Drag Chain Regularly

Regular inspection is the first and foremost preventive maintenance tip for plastic drag chains. Inspecting the drag chain on a regular basis enables you to identify and correct any potential issues before they turn into bigger problems. Inspect the drag chain for any signs of wear and tear such as cracks, chips, or broken links. If you notice any damage, replace the affected section of the chain immediately.

2. Keep the Drag Chain Clean

Dirt and debris can accumulate on the drag chain over time, leading to increased friction and wear. To prevent this, it is important to keep the drag chain clean. Use a soft brush or cloth to remove any dirt or debris that may have accumulated on the chain. Avoid using harsh chemicals or abrasive materials that could damage the chain.

3. Lubricate the Drag Chain

Lubrication is another important preventive maintenance tip for plastic drag chains. Lubricating the drag chain reduces friction, minimizing wear and tear and extending the lifespan of the chain. Use a high-quality lubricant that is specifically designed for plastic drag chains. Be sure to apply the lubricant evenly and avoid over-lubricating the chain.

4. Check the Tension of the Drag Chain

The tension of the drag chain is an important factor that can affect its performance. A chain that is too loose or too tight can cause premature wear and tear. Check the tension of the drag chain regularly and adjust it as needed. A general rule of thumb is to maintain a tension of around 3-5% of the chain’s total weight.

5. Replace the Drag Chain When Necessary

Despite regular maintenance, plastic drag chains will eventually wear out and need to be replaced. The lifespan of a drag chain depends on several factors, including the frequency of use, the environment it is used in, and the amount of wear and tear it experiences. When the drag chain shows signs of significant wear, it is time to replace it. Using a worn-out drag chain can lead to increased downtime, reduced productivity, and even safety hazards.


Preventive maintenance is crucial for ensuring the optimal performance and longevity of plastic drag chains. Regular inspection, cleaning, lubrication, and tension checks are all essential. When a drag chain shows signs of wear and tear, it should be replaced promptly. By following these preventive maintenance tips, you can keep your plastic drag chains in top condition and ensure the smooth operation of your industrial systems.
