Hey there! I'm a supplier of welded chains, and today I wanna chat about the lubrication requirements for welded chains. Welded chains are used in a whole bunch of industries, from manufacturing to agriculture, and proper lubrication is super important for their performance and longevity.
First off, let's talk about why lubrication is necessary. Welded chains are constantly in motion, with the links rubbing against each other and the sprockets. This friction can cause wear and tear, leading to chain elongation, reduced efficiency, and even premature failure. Lubrication helps to reduce this friction, protecting the chain and ensuring smooth operation.
There are several types of lubricants that can be used for welded chains. The most common ones are mineral oils, synthetic oils, and greases. Mineral oils are the most basic and affordable option. They're good for general-purpose applications where the operating conditions aren't too extreme. Synthetic oils, on the other hand, offer better performance in high-temperature, high-speed, or heavy-load situations. They have better oxidation resistance, lower volatility, and can provide longer-lasting lubrication. Greases are thicker and stickier than oils, which makes them ideal for applications where the chain is exposed to dirt, dust, or water. They can form a protective barrier that keeps contaminants out.
Now, let's get into the specific lubrication requirements based on different chain types.
Din763 Link Chain
Din763 Link Chain is often used in light to medium-duty applications. For this type of chain, a light to medium-viscosity mineral oil is usually sufficient. You should apply the lubricant evenly along the length of the chain, making sure it gets into the spaces between the links. It's recommended to lubricate the chain regularly, especially if it's operating in a dirty or dusty environment. A good rule of thumb is to lubricate it every few hundred hours of operation, but you might need to do it more often if the conditions are harsh.
Grade 80 Alloy Chain
Grade 80 Alloy Chain is known for its high strength and is commonly used in heavy-duty lifting and towing applications. Due to the high loads it can handle, this chain requires a high-quality lubricant. Synthetic oils are a great choice here because they can withstand high pressures and temperatures. You need to make sure the lubricant penetrates deep into the chain links to provide maximum protection. Lubrication intervals for Grade 80 Alloy Chain are typically shorter, maybe every 100 - 200 hours of operation, depending on the usage intensity.
Din764 Link Chain
Din764 Link Chain is used in various industrial applications. Similar to the Din763, a medium-viscosity lubricant is suitable. Whether it's a mineral oil or a synthetic blend depends on the specific operating conditions. If the chain is exposed to moisture, you might want to consider a lubricant with anti-corrosion properties. Apply the lubricant at regular intervals to prevent rust and wear.
Ordinary Mild Steel Link Chain
Ordinary Mild Steel Link Chain is more commonly used in less demanding applications. A basic mineral oil can work well for this type of chain. However, since mild steel is more prone to rust, it's important to lubricate it regularly, especially if it's used outdoors or in a humid environment. You can apply the lubricant by brushing it on or using a spray application for more even coverage.
Din766 Link Chain
Din766 Link Chain is often used in conveyor systems and other machinery. For this chain, a lubricant that can provide good adhesion is important because the chain might be subject to vibration and movement. Greases are a popular choice for Din766 Link Chain as they can stay in place better. Make sure to apply the grease to the critical areas of the chain, like the pin-bushing interfaces.
When it comes to applying the lubricant, there are a few things to keep in mind. First, clean the chain before lubrication. Dirt and debris on the chain can mix with the lubricant and cause more damage. You can use a mild solvent or a chain cleaner to remove any contaminants. Second, apply the lubricant evenly. You can use a brush, a spray gun, or an automatic lubrication system. If you're using a brush, make sure to get into all the nooks and crannies of the chain. If you're using a spray, hold the can at a proper distance to ensure a good spray pattern.
It's also important to store the lubricant properly. Keep it in a cool, dry place away from direct sunlight. Follow the manufacturer's instructions for storage temperature and shelf life. Expired or contaminated lubricants might not work as effectively and could even cause damage to the chain.


In conclusion, proper lubrication is crucial for the performance and lifespan of welded chains. Different chain types have different lubrication requirements based on their application, load, and operating conditions. By choosing the right lubricant and applying it correctly at the right intervals, you can ensure that your welded chains operate smoothly and last longer.
