Properly maintaining and lubricating chains is essential to optimize performance and extend the lifespan of machinery and equipment. Choosing the right chain lubricant and applying it correctly are important to enhance chain performance, reduce operational costs, and increase durability.

Remove the coating from a new chain

Chains are often coated with an oil, wax, or other protective product. These coatings are applied to prevent corrosion during storage and transportation but do not provide anti-wear properties. Before a chain can be lubricated and installed, these coatings must be removed to allow the chain lubricant to effectively reach the critical wear points.

Failure to remove the protective layer can lead to various problems:

• Forming a barrier that prevents the chain lubricant from penetrating the key wear areas of the chain.
• Retaining metal particles and production residues that can cause premature chain damage.
• Increased friction and wear, shortening the chain's lifespan.
• Thorough cleaning is a crucial first step in preparing the chain for lubrication and installation. Skipping this step can negate even the best maintenance efforts.

Clean first, then lubricate

Effective lubrication starts with a clean chain. All traces of wax, oil, dirt, and other residues must be removed. Use a powerful cleaner that quickly dissolves contamination, such as the Eurol Specialty Swift Clean 130. For applications in the food industry, the H1-certified Eurol Swift Clean 110 FD is a suitable choice.

Lubricate with grease or oil?

Whether to use grease or oil depends on the specific application. Both options have advantages and limitations.

Grease: Grease is best for chains equipped with grease nipples. However, grease applied to the surface of a chain can form a barrier that prevents lubrication of critical wear points. Over time, grease can mix with contaminants, resulting in a grinding paste that accelerates wear and shortens the chain's lifespan. Chains operating underwater are often lubricated with grease because they provide better protection in this situation.

Oil: Oil is typically the better choice for chain lubrication. Oil can penetrate hard-to-reach areas, such as pins and bushings, providing long-lasting lubrication and protection. When applied correctly, oil reduces friction, minimizes wear, and extends the chain's lifespan.

Use a dry lubricant

Our practical experience shows that a dry lubricant is ideal for chains in industrial applications. Dry lubricants are often oils that prevent dirt and contaminants from adhering to the chain, keeping chains clean and operational. An important property of a dry lubricant should be its ability to penetrate deeply into wear areas and provide protection there. Make sure the dry lubricant you intend to use is compatible with automatic lubrication systems, making it suitable for industrial applications.

An example of a dry lubricant is Eurol Specialty Lube PL. There is also the Eurol Specialty Lube PL FD food-grade variant, which is NSF H1-certified and developed for the food industry and chains in the agricultural sector, such as harvesting machinery. For chains operating in extreme conditions within the food industry, such as baking ovens, there is the Eurol Specialty Chain Lube S-HT 220 FD. Finally, there is the Eurol Specialty Lube PL BIO, which is a biodegradable dry lubricant.

All these dry lubricants contain the SYNGIS Technology, which ensures protection even under the most extreme conditions.

If you want to lubricate a chain that runs in (salt) water, we recommend spraying it first with a dry lubricant and then greasing it. The Eurol Specialty CS-2/502-S grease with high-viscosity base oil is highly suitable for this purpose. This product is also resistant to extreme temperatures.

Uncertain? Seek advice!

Choosing the right lubricant for chains is essential for extending the lifespan of your machines and optimizing performance. Whether you opt for grease, oil, or a dry lubricant, it is important to properly prepare the chain by removing protective coatings and ensuring a thorough cleaning before you start lubricating.
