One of the most important components of a chainsaw is the chainsaw chain. It is made up of steel links that are connected by rivets. While it superficially resembles a roller chain like those used on bicycles, the chainsaw chain design is actually more akin to a leaf chain design.

When replacing a chainssaw chain, be sure to follow the manufacturer's recommendations for length. The manufacturer will specify the length on the package of the chain. It is also helpful to know the bar length, gauge, and pitch of the chain before buying a replacement. You can use this information to determine whether the chain you're buying will work with your chainsaw.

The chain of a chainsaw is arranged in a particular way, with a cutter on each end. The chain is powered by a motor, which powers the drive cog. The length of the chain is determined by the number of lugs, sometimes called drive links. Most home-use chainsaws have this configuration.

During routine use, the chain may become worn and need to be replaced. This happens because the links of the chain can become dull and fragile. The best solution is to replace the chain at least twice as often as you replace the blade.
