What Are the Differences Between Sealed and Lubricated Track Chains?

Track chains are an essential component for construction equipment such as bulldozers, excavators, and loaders. They provide traction and movement for these construction machines. However, not all track chains are created equal. There are sealed and lubricated track chains, each with its advantages and disadvantages.

Sealed track chains are also known as dry chains. They are manufactured with seals to prevent dirt and other debris from entering the chain, thus reducing the need for frequent maintenance. The seals also prevent oil from leaching out of the chain. This type of chain is ideal for use in areas with high levels of dust and debris. It is also environmentally friendly as the seals help prevent oil leakage which can be harmful to the environment.

On the other hand, lubricated chains require regular greasing, typically after about 50 hours of machine operation. They are designed to hold oil or grease between the pins and bushes, which helps reduce the amount of wear and tear on the chain. Lubricated chains offer superior durability and last longer than sealed chains. The downside is that they require more maintenance, including regular oil or grease changes.

The choice between sealed and lubricated chains will depend on the specific job requirements. If you are working in dusty and dirty environments, sealed chains are a better option because they require less maintenance. On the other hand, lubricated chains provide superior durability and are therefore ideal for harsh environments with heavy machinery operation. Additionally, lubricated chains are preferred for heavy-duty construction jobs such as excavating and mining.

In conclusion, the choice between sealed and lubricated chains will ultimately depend on the specific requirements of the job. Both types have their own advantages and disadvantages, and it is important to consider these before making a final decision. Proper maintenance and regular inspections can help extend the life of the chains, regardless of the type chosen.
