How is chainsaw bar measured

However, longer bars do exist and can exceed 24 inches. When taking a measurement, you should round to the nearest even whole number. Note: Bar lengths and other metrics like pitch, gauge, and drive links can be found on the existing bar in some cases. Pictured below is my husqvarna with chainsaw bar and chain metrics detailed. Once you have the bar length you can simply buy a replacement bar that meets that length requirement.

Note: While these numbers are usually indicative of the noted length, certain brands like Stihl like to be different. Stihl however, can use The rivets are the small, round studs that hold the chain segments together.

Do not measure the overall length as this will give you the wrong size. When you measure the cutting length as shown above round it up to the nearest inch, This will give you your length. Chainsaw Chains come in all types and sizes, if you have the correct information for your Chain then its very simple to get a replacement, if not then i am going to explain to you the best ways to ensure you get the right chain.

As you can see in the image above you will need to measure the distance between three consecutive rivets, this can be done anywhere on the chainsaw. This information will include everything you need to find a matching chain.

Fortunately, with the information you learned here, you no longer have to wonder how do you measure a chainsaw bar or chain because you now know how to do it. Or see what else is available, regardless of price, in my post on the top chainsaws.

That page includes the best of the best when it comes to high-quality chainsaws. Replacing the Bar Once you have the effective cutting length as well as the true length of the bar, you only need to match up the two numbers for a perfect fit. Measuring the chain is more complex than measuring the bar, and it requires you to take and match two main measurements: pitch, and gauge. To take the first measurement, you will need to count the number of links from end to end.

This measurement may seem strange to many people, but it affects the way the chain goes around bends at the tip and base. If the chain has the wrong number of links, it will not move across the bar smoothly, and it could get jammed up in the base.

Pitch is the distance between drive links in your chain. To get this measurement, you need to measure the distance between any three consecutive rivets, then divide that number by two. Gauge is the measurement of the groove that keeps the chain on the bar as it cuts. There are several common gauges, including. You can use a tape measure or ruler to measure the gauge, or you can also use a penny, dime, or quarter if you have the most common gauges.

Most brands put the information you need right on the bar for you. You can see it by removing the cover that hides the end of the bar. If you measured the bar earlier in this guide, you have likely seen numbers printed on it. You only need to match up these numbers with the number on your package, and for a perfect fitting chain. You should always take the time to get the measurements you need and never estimate or guess at the measurements.

Besides wasting money and dealing with frustrating returns, you can permanently damage your saw and injure yourself. Keeping the chain well-oiled while you are working is vital to its longevity.
