The number on a chain saw chain refers to the pitch, which is measured in a fraction of an inch. The “pitch” of a chain saw chain is defined as the distance between any three consecutive rivets divided by two.
This number is usually stamped onto the drive link of the chain.
The most common pitches are. 050 (1/4 inch). 058 (3/8 inch) and. 063 (3/8 inch). Generally, the bigger the gauge of the chain the more power it can handle, and the lower the number, the faster the chain can cut.
Therefore, a higher number on a chain saw chain indicates a larger, more powerful chain suitable for thicker, tougher woods. Conversely, a lower number indicates a smaller, less powerful chain ideal for smaller and softer woods.
How can I tell what size chain is on my chainsaw?
In order to tell what size chain is on your chainsaw, you need to measure the drive link thickness. The drive link is the part of the chain that fits into the drive sprocket and moves the chain around the bar.
To measure it, first make sure the chain is installed and tensioned correctly, then you should use calipers to measure the link on the bottom of the chain where it runs around the guide bar. The measurement should be taken at the point where the link touches the bar.
Once you have this measurement, you can compare it to the size specifications found in the owner’s manual or on the inside of the chain cover or the chainsaw box. Common sizes range from 0.043 inches (1.09mm) to 0.
058 inches (1.47mm), with different brands having their own letter and number codes to denote chain size and pitch. Once you have determined the chain size, you can buy the appropriate chain for your chainsaw and install it.
How do you read a chainsaw bar number?
Reading the numbers on a chainsaw bar can be done quickly and easily. The bar number is typically printed near the bar, and it can be identified by its model number followed by the size of the bar. For example, if you have a bar labeled “M420120,” the numbers indicate that the bar is a model 4, 2.
0 mm (or 20 cm) in length. You can then look up the model number in the manufacturer’s manual to identify the exact specifications of the bar. Always make sure you are using the correct chainsaw bar size and type for best results and safety.
What size file do you use on a 3/8 chain?
When using a 3/8 chain, it is important to use a file that is the appropriate size in order to ensure safe and efficient operation. The ideal size of file to use with a 3/8 chain is a 5/32 file. This size is considered to be the standard size file and is recommended to be used as it will provide the best results.
Additionally, it is important to check the specifications of your chain to make sure that the 5/32 file is the correct size for the application. A file that is too big can damage the chain, whereas a file that is too small may not be able to remove debris from the chain’s cutting teeth, leading to a decrease in effectiveness.
In order to ensure optimal performance and life of your 3/8 chain, use a 5/32 file and check the specifications before use.
What do chain numbers mean?
Chain numbers refer to a type of measurement of a bicycle chain’s overall length. They are typically expressed as a two- or three-digit number, and they measure the length of a single link in fractions of an inch.
Generally, the first number is the integral number of inches, and the second is the fractional inches, with a third number for partial-link chains. The current standard for new bicycles is the block link, with a chain number of 1/2 X 11/128.
This means that each individual link is 1/2 inch long and has 11 edges, each with a radius of 1/128ths of an inch. Knowing the chain number of a particular bicycle chain is important because the length needs to match the number of teeth on the sprocket, or else the chain won’t run smoothly or possibly won’t fit at all.
What Stihl chain cuts the fastest?
The Stihl Rapid Super chain is their fastest cutting chain. This chain has been designed with a narrower nose profile and a shallow cut depth compared to other chains. This reduces the number of teeth passing through the wood at each stroke, resulting in faster cutting speeds.
Additionally, the Rapid Super chain is made with a special carbide cutting profile that allows it to stay sharper for longer and make faster shallow cuts. This helps reduce the amount of time spent on a single cut, allowing you to cut faster, with less effort.
Finally, the Rapid Super chain is equipped with a Full Chisel 3/8” pitch design that has fewer filing requirements, allowing you to get more consistent performance and max cutting speed over time.
Whats the difference between green and yellow Stihl chains?
The main difference between green and yellow Stihl chains is in the type of chain. Green Stihl chains are quick-cutting chains meant for general-purpose saw applications, while yellow Stihl chains are semi-chisel chains that use more powerful cutters for more specific jobs.
Green chains are more versatile and can be used for multiple applications, while yellow chains are better suited for more specific projects and professional use. As far as strengths go, yellow chains generally have greater cutting power than green chains due to their sharper cutters, but it is important to keep in mind that the factors of speed and wear are also affected by the type of chain.
All in all, the decision between green and yellow Stihl chains really depends on what your sawing needs are.
How are chains numbered?
Chains are numbered according to the number of links in the chain. The number of links can range from as few as eight to as many as 130. Chains are divided into three different categories based on the size of the link pitches: 0.25”, 0.
375” and 0.5”. Each of these categories has its own numbering system, which can be found in the chain manufacturer’s specifications. Generally, the number displayed on the chain is a measurement of how long the chain is if it were fully extended in one line.
This measurement is referred to as the Pitch Length and is divided into how many links are in the chain. For example, a #25 chain has a Pitch Length of 25″ and contains 25 individual links or pins. Alternatively, 1/2″ pitch chains are often referred to as #50 chains and have 50 links, while 3/8″ pitch chains are referred to as #35 chains and have 35 links, respectively.
Some chains, particularly those used in heavy-duty applications, are also marked with a rivet length, which represents the length of the individual links in the chain.
How do I measure my chain size?
Measuring your chain size is relatively simple and can be done with a few tools. The most accurate way to measure your chain size is to use a chain checker tool or ruler. Most chain checker tools have a row of pins that are used to measure the out-side distance between the rollers on your chain.
To use the tool, simply insert the pins into the side plates of your chain and line the pins up with the inner plates of the same links. Then measure the distance between the pins with a ruler to get an exact measurement of your chain.
Another, simpler method of measuring your chain size is to take your chain off the bike and measure it straightened out on a flat surface. To do this, line up two consecutive chain links and lay a ruler over them.
Then measure the pitch, which is the distance between the two link pins and should read exactly half an inch for a 1/2 inch pitch chain. Once you have an accurate pitch reading, you can then measure the length of your chain to get an exact measurement.
When measuring your chain size, it is important to use an accurate ruler and chain checker tool to ensure that your chain is the correct size. With the right tools, measuring your chain size should be a quick and easy process that will help ensure that your bike is running in peak condition.
What size is a 525 chain?
A 525 chain is an industry-standard size for smaller sprocket-style motorcycles, consisting of 80-links accompanied by a 1/8 inch width. Generally, a 525 chain is found on lightweight, 125cc – 1000cc motorcycles, quad-bikes, dirt bikes and Go-Karts.
It is a racing standard chain and its design gives it a lower weight and a smooth transition of power. Their high strength and low weight make them particularly suited for the high performance and drag racing applications, while their increased flexibility and non-riveted design makes them suitable for everyday use.
This chain is also a great option for custom builds and repairs, thanks to its compatibility with most standard sprockets and offering an alternative to the heavier 428 chain.
