So, the best way to prevent chain failure is to create and enforce a maintenance program that outlines how often lubrication is needed for your chains.

There are many reasons why these chains and chain drives suddenly fail, including contamination, fatigue, or wear and tear. However, chain failures are almost always a direct result of lubrication issues.

Lastly, automatic chain lubrication systems operate continuously. When working correctly, daily inspection of the chain or sprocket during operation is typically not necessary. Automatic systems help reduce maintenance and service costs while increasing machine utilization. The most common lubrication chain systems are force-feed and oil-ring.

Another way to keep your chains constantly lubricated is by implementing a semi-automatic drip lubrication system. This chain lubrication system manages the number of drops per minute and hour and ensures that the lubricant covers the entire chain width, rollers, and inner and outer link plates. Most drip lubrication systems drop anywhere from five to 20 drops a minute. The drip system manages the frequency and uniformity of the drops, and the number of links in the chain defines the number of drops.

This system is typically used when the driven chain must handle high operating speeds and loads or high temperatures, such as in excavators, bulldozers, robotic systems, turbines, and generators, or in a highly contaminated environment.

In the industrial world, manual lubrication is typically reserved for smaller productions where there wouldn’t be much impact from turning off machinery or equipment.

Drip lubrication is often used in conveyor systems in multiple industries, such as automotive, mining, and food and beverage, where chains need to operate continuously.

Oil-ring systems are commonly used in moderate-speed, continuous-duty applications. They are preferred over force-feed systems when there are budget constraints or when there are a large number of units or equipment that need to be maintained, like HVAC systems.

Force-feed lubrication systems provide a timed and continuous spray through a distribution pipe where the oil covers a specific surface area of the chain.

Manual lubrication involves using hand-held tools like grease guns, filler pumps, grease pumps, brushes, small oil cans, or aerosol sprays to lubricate specific points. This method should be done every eight to ten hours, depending on the machine or equipment’s operating procedures, and equipment must be offline/powered off. This method is known for being very time-consuming and sometimes even dangerous, based on the type of machinery or equipment being maintained.

Oil-ring systems use rotating discs that gather the oil from a reservoir at the bottom of the drive chain system. The oil is then sprayed or jettisoned against a collector plate, which is then dropped on the bottom of the chain. With these systems, the amount of lubricant is managed to ensure the chain is never entirely immersed in the lubricant. The primary difference between oil-ring and force-feed systems is that oil-ring systems don’t need pumps or external power—they rely on gravity and the rotational motion of the ring to provide lubrication.
