Things To Consider When Measuring Chainsaw Bars

There are a few different things that you’ll need to take into account when measuring your chainsaw bar. In this section, we’ll discuss each one in more detail so that you can get an accurate measurement every time.

  • The first thing you need to know is the pitch of your chain. The pitch is the distance between any three rivets divided by two. It’s important to know this because it will determine the gauge, or thickness, of the bar.

You can usually find this information stamped right on the chain itself. If not, consult your owner’s manual or ask a salesperson at your local hardware store for help in determining the pitch of your particular model.

  • Once you know the pitch, you can move on to measuring the length and width of the bar itself.

Now that you know how to measure your chainsaw bar, it’s time to learn about the different types of bars available. In the next section, we’ll discuss the three most common types of chainsaw bars and their best uses. Stay tuned!

Types of Chainsaw Bars

There are three main types of chainsaw bars: solid, sprocket-nose, and double-ended. The type of bar you choose will depend on the size and power of your saw as well as the type of wood you’ll be cutting. Let’s take a closer look at each one.

Solid Bars

A solid bar is just what it sounds like – one solid piece of metal with no moving parts. These bars are the most durable and longest-lasting, but they’re also the heaviest. That’s why they’re mostly used on larger, more powerful saws.

Sprocket-Nose Bars

A sprocket-nose bar has a small wheel with teeth (called a sprocket) at the end. This type of bar is lighter than a solid bar and therefore easier to maneuver.

It’s also less likely to get jammed with branches and other debris. However, because of the way the sprocket is designed, these bars wear out faster than solid bars.

Double-Ended Bars

A double-ended bar is simply two solid bars welded together in the middle. These bars are lighter than solid bars but not as light as sprocket-nose bars.

They’re also more durable than sprocket-nose bars and less likely to get jammed. However, they can be more difficult to maneuver in tight spaces.

Now that you know the different types of chainsaw bars available, you can start shopping for a replacement bar for your saw.
