Normal wear can make it difficult to accurately measure chain gauge on a worn chain. “Chain pitch is the size of the chain and is defined as the distance between any three consecutive rivets divided by two. Oregon chain is made in several pitches – 1/4″ is the smallest, 3/8″ is the most popular, and 3/4” is the largest. Saw chain sequences include: standard, semi-skip, and skip.
how to identify chainsaw chain size Related Question:
How do I know what size my chainsaw chain is?
To determine the pitch (chain size), you’ll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.
What is the difference between .325 and 3/8 chain?
The . 325 may be smaller and faster, but it may not be your best bet for your everyday needs. The three-eighths-inch chain is durable and lasts longer than its smaller cousin. This makes it one of the more popular switches for chainsaw users who want to get more out of their saw.
Is 40 and 41 chain the same?
The differences between 41 roller chain and 40 roller chain are the roller width and diameter, plate height and thickness, overall width, and tensile strength.
What’s the difference between 404 and 3/8 chain?
Secondly, the numbers 3/8″ and . 404″ refer to the pitch (distance) between the drive links – these are the bits on the chain that stick down and engage with the drive sprocket on the saw, and the sprocket on the roller-nose end of the bar.
What is the difference between a R56 and a S56 chainsaw chain?
The difference is the width of the chain track. S56 is . 050″ and R56 is . 043″.
What do Stihl chain numbers mean?
Find the gauge of the chain by locating the number stamped on the drive link. A 1 equals a 0.043-inch gauge, 3 equals a 0.050-inch gauge, 5 corresponds to a 0.058-inch gauge, 6 means the chain has a 0.063-inch gauge. A 0 means the chain has a 0.080-inch gauge, but this gauge size is found only on the Harvester chain.
Are .325 and 3/8 chains interchangeable?
You can replace a 3/8 Oregon PowerMatch nose with a . 325 PowerMatch nose on any length of Oregon PowerMatch bar you want. Then when you use up the . 325 chain just put the 3/8 nose and rim sprocket back on.
What is the correct file size for 325 Stihl chain?
325″ Pitch Saw Chains. STIHL Files come specifically designed for each pitch of saw chain, with this particular round file suited for use with a . 325″ pitch chain. The file size is 4.8mm x 200mm.
What does the numbers on a chain saw chain mean?
0.050″ (1.3 mm) and 0.058″ (1.5 mm) are most common, 0.043″ (1.1 mm) and 0.063″ (1.6mm) less common. Pitch and gauge together determine the size of chain. Length is determined by counting the number of drive links, also called drive lugs. (see picture below).
What does 520 mean on a chain?
Usually, bushings separate the rollers from the pins, but there are bushing-less designs. (3) The size of a chain is designated by a three-digit number (520, for example). The distance from the center of one pin to the center of the next is called pitch. Pitch is represented by the first digit, which is 4, 5 or 6.
Whats the difference between 520 and 530 chain?
A 520 chain is a smaller pitch chain. Pitch being the distance between rollers. The 520 is a lighter weight chain than the 530. That is why people switch to the 520, but it may not last as long as a 530.
What the difference between a 520 and 525 chain?
The 5 part just describes the distance between the centers of the link pins (or wherever on the links, basically how long a link is) and the next two numbers describe the width of the chain. So a 520 chain is going to be narrower than a 525(and thus require a narrower front and rear sprocket) and lighter
How do I tell what grade my chain is?
Just look for the “L” and then the number after it. Each number following the “L” corresponds with a grade of chain. On grade 70 this can also show that the chains are DOT approved! The “L” represents Laclede and our commitment to high quality chain products.
What is the difference between 1 8 and 3/32 chain?
A 1/8″ chain is the most common chain found on single speeds, and 3/32″ chain is the most common chain found on derailleur equipped bikes. A 1/8″ chain will fit on parts that are either width. 3/32″ chains will only fit on parts designed to work with 3/32″ chains.
What is a 420 chain?
– All PEER roller chains incorporate solid rollers enhancing rotation on the. bushing while reducing impact loads on the sprocket tooth during operation. – All chain components are heat treated to achieve maximum strength. and greater wear resistance.
