Common Conveyor Chain Failure Issues and How to Avoid Them

Conveyor chains are essential components in all kinds of material handling systems. They are used extensively across a wide range of industries, from manufacturing, cement production and mining to food production and bakery operations. However, even the highest-quality chains can fail if they are not properly maintained or correctly fitted. At John King Chains, we understand how costly unexpected downtime can be for your business, and how important it is to spot potential conveyor chain failure early.

So, what are some of the most common conveyor chain failures? And more importantly, how can you avoid them?

1. Overloading the Conveyor Chain

Overloading is one of the most common causes of conveyor system failure. This occurs when a chain is subjected to loads beyond its designed capabilities, leading to excessive strain being placed on its components. This can lead to accelerated wear, elongation, and even breakage.

How to avoid it: Always ensure that the chain you select matches the load requirements of your application. Partnering with an experienced manufacturer and conveyor chain supplier like John King Chains ensures you receive a chain with the correct tensile strength and load capacity for your operations.

2. Poor Lubrication

Insufficient lubrication or application of the wrong products can significantly reduce the lifespan of conveyor chains. Lubrication is vital to reduce friction between moving parts, which can lead to increased wear on pins, bushers and rollers.

How to avoid it: Implementing a regular lubrication schedule will help to ensure your conveyor systems are properly maintained at all times. In addition, you should always check that you are using the correct lubricant. In high-temperature or dusty conditions, specialised lubricants may be required to maintain optimal performance.

3. Misalignment Issues

Misalignment between the chain and sprockets is another common cause of conveyor system failure. When chains are misaligned, the risk of conveyor issues such as uneven wear, increased noise, and premature failure can be significantly increased. Even minor misalignment can place unnecessary strain on the chain.

How to avoid it: Ensure your conveyor systems are inspected regularly to maintain proper alignment of chains and sprockets. Correct installation and routine maintenance checks are essential for preventing misalignment and the resulting long-term damage it can cause.

4. Environmental Factors

Conveyor chains are often required to operate in harsh environments. They may be exposed to moisture, chemicals, extreme temperatures, or abrasive materials that can affect their integrity. Such conditions can lead to wear, corrosion, and reduced performance over time.

How to avoid it: Always select chains made from materials suited to your environment. For example, corrosion-resistant coatings or heat-treated components can significantly improve the durability of conveyor chains in challenging conditions. In addition, regular cleaning and maintenance checks will help to minimise environmental impact.

5. Incorrect Chain Selection

Finally, using the wrong type of chain for your application is a major contributor to system failure. Each industry and application has unique requirements, and a standard conveyor chain may not always be the most suitable choice.

How to avoid it: Work with a trusted manufacturer who can help you identify the most suitable chains and accessories for your operations. An experienced engineer can select the right conveyor chain design, material, and configuration for your application. At John King Chains, we provide both standard and bespoke solutions tailored to your specific needs.
