Chain lubrication is a critical aspect of maintenance that often gets overlooked by maintenance practitioners, leading to significant operational issues. The proper lubrication of chains is essential to ensure smooth operation, prevent wear and tear, and extend the life of the equipment. However, many common mistakes are made in chain lubrication practices, such as the use of inappropriate lubricants like used oils and greases. These errors can lead to a range of problems, including chain elongation, breakages, and unsmooth, jerky movements. 

In the industrial sector, particularly in environments where metalworking fluid manufacturers operate, the importance of correct chain lubrication cannot be overstated. Chains are subjected to high-load, metal-to-metal contact, especially at the pin-roller-bushing interface, making it crucial to use the right type of lubricant. The consequences of neglecting this aspect of maintenance can be costly, both in terms of equipment failure and potential safety hazards. 

The Importance of Using the Correct Lubricant 

Understanding the conditions under which chains operate is the first step in selecting the right lubricant. Chains function under boundary lubrication conditions, where there is a minimal separation between metal surfaces. This results to high friction and wear if not properly lubricated. Using incorrect lubricants, such as grease or used oils, can exacerbate these issues. 

Greases, for example, lack the creeping or penetrative capabilities needed to seep into the critical areas of the chain, such as the pin-roller-bushing interface. This inability to reach these areas leads to inadequate lubrication, which can cause chain elongation and eventually result in chain breakages. Similarly, used lubricants, which are often contaminated with sludge or carbon, can clog the entry points of oils into the chain’s moving parts. These contaminants reduce the lubricant’s effectiveness and increase the risk of mechanical failure. 

Inappropriate lubricants also cannot provide the high viscosity and extreme pressure (EP) additives required for chains operating under boundary friction regimes. Hydraulic oils, which are sometimes mistakenly used, do not possess the viscosity levels—such as ISO VG 320—needed to protect the chain from the high pressures and temperatures encountered during operation. The absence of these critical properties in the lubricant can lead to increased wear, reduced efficiency, and ultimately, equipment failure. 

Characteristics of an Ideal Chain Lubricant

An ideal chain lubricant must have specific characteristics to perform effectively under the demanding conditions in which chains operate. One of the most important qualities is the lubricant’s ability to penetrate deeply into the chain’s pin-roller-bushing areas. This creeping capability ensures that the lubricant reaches all the critical contact points within the chain, providing a protective film that minimizes metal-to-metal contact and reduces wear. 

High chain oil viscosity and EP additives are also essential features of a good chain lubricant. These properties ensure that the lubricant can withstand the high pressures and temperatures typically encountered in industrial chain applications. Lubricants with lower chain oil viscosity or without EP additives are less effective at preventing wear and may even contribute to the premature failure of the chain. 

​​Applying ​used lubricants is highly discouraged. Used oils often contain contaminants such as sludge, carbon, and metal particles, which can clog the chain’s moving parts and hinder the lubricant’s ability to protect against wear and tear. The presence of these contaminants can also speed up the degradation of the lubricant, leading to more frequent maintenance and higher operational costs. 

The Role of Tackifiers in Chain Lubrication 

Tackifiers are another crucial component of an effective chain lubricant, especially in the context of industrial chain lubrication. These additives enhance the lubricant’s ability to adhere to the metal surfaces of the chain, reducing the likelihood of drip-offs and ensuring that the lubricant remains in place even under heavy loads and at high temperatures. This adhesion is important in industrial environments, where dripping lubricants can create unsafe working conditions and contribute to contamination. 

In manufacturing environments where chains are often used to convey goods, the use of lubricants with tackifiers can prevent unwanted migration or contamination of the products being handled. This is especially critical in industries where cleanliness and product integrity are paramount, such as in the food and beverage sector or in precision manufacturing. 

Tackifiers also play a vital role in maintaining an even, uninterrupted film on the chain, which is essential for preventing rust and corrosion. By ensuring that the lubricant remains in place, tackifiers help to protect the chain from environmental factors that could lead to degradation, such as moisture and contaminants. This protection extends the life of the chain and reduces the need for frequent maintenance, ultimately lowering operational costs.
