High Temperature Chain Lubrication

12 June 2023

In industries where high-temperature environments and heavy mechanical loads are commonplace, proper chain lubrication becomes crucial. Chains are essential components in many applications, including manufacturing, automotive, and food processing. To ensure optimal performance and extend the life of chains operating in extreme conditions, understanding the impact of evaporation rates, choosing high-performance oils, avoiding over-lubrication, and minimising power consumption are key considerations.

1. The Influence of Evaporation Rate on Oil Lifespan:

High temperatures accelerate the evaporation of lubricating oils, leading to decreased oil life and diminished protection for the chain. This evaporation phenomenon is particularly critical when temperatures exceed 220 degrees Celsius. Oils with slower evaporation rates are more resilient and provide prolonged lubrication under extreme conditions. By selecting oils that have been specifically formulated for high temperatures, the risk of premature oil degradation can be significantly reduced.

2. Cost-Effectiveness of Higher Performance Oils:

While higher-performance oils may come at a higher initial cost, they often prove more cost-effective in the long run. These oils are engineered to withstand extreme temperatures, resist evaporation, and maintain their lubricating properties over an extended period. By investing in such oils, businesses can avoid frequent oil replacements, reduce maintenance downtime, and enhance the overall lifespan of chains, ultimately leading to cost savings in the long term.

3. The Pitfalls of Over-Lubrication:

Applying excessive lubrication to chains can be detrimental, particularly in high-temperature environments. Over-lubrication can result in excess oil accumulation, leading to the formation of gumming and deposits on the chain surfaces. These deposits attract contaminants, increase friction, and impede the smooth operation of the chains. Striking the right balance between adequate lubrication and avoiding over-lubrication is crucial for maintaining optimal chain performance and preventing unnecessary maintenance issues.

4. Power Consumption Reduction with Correct Lubrication:

A properly lubricated chain operates with reduced friction, resulting in lower power consumption. Inefficient or inadequate lubrication increases friction, requiring more energy to overcome resistance and power the system. By employing the right lubrication practices, businesses can optimise energy usage, enhance efficiency, and potentially realise substantial energy savings over time.

5. Differential Evaporation Rates at High Temperatures:

When considering high-temperature chain lubrication, it's essential to note the variations in evaporation rates among different oils. Some oils exhibit slower evaporation rates at temperatures above 250 degrees Celsius, while others may evaporate more slowly around 220 degrees Celsius. Understanding these differences allows businesses to choose oils tailored to their specific operating conditions, maximising chain performance and minimising the need for frequent re-lubrication.


In high-temperature environments, effective chain lubrication is vital for maintaining productivity, preventing premature chain wear, and optimising energy usage. By selecting oils with slower evaporation rates, investing in higher performance lubricants, avoiding over-lubrication, and considering differential evaporation rates at extreme temperatures, businesses can significantly enhance chain longevity, reduce maintenance costs, and improve overall operational efficiency. Prioritising proper chain lubrication ensures smooth operations, increased equipment reliability, and a more sustainable business model in the long run.
