Chainsaw Chain Speed Calculator
FAQs
What is a good chain speed for a chainsaw? A good chain speed for a chainsaw is typically around 60 to 80 feet per second (fps). This speed allows for efficient cutting while maintaining safety and control.
How is chainsaw chain speed measured? Chainsaw chain speed is typically measured in feet per second (fps) or meters per second (m/s). It’s calculated by multiplying the RPM (revolutions per minute) of the chainsaw engine by the circumference of the chainsaw bar.
What does 72 mean on a chainsaw chain? The number 72 on a chainsaw chain refers to the number of drive links on the chain. Each drive link engages with the chainsaw’s drive sprocket, and the number helps identify the correct replacement chain for the chainsaw.
What does 20 mean on a chainsaw chain? The number 20 on a chainsaw chain usually refers to the chain’s pitch, which is the distance between any three consecutive rivets divided by two. It helps match the chain to the correct bar and sprocket.
What type of chainsaw chain cuts fastest? Full-chisel chains are generally considered the fastest-cutting chainsaw chains. They have aggressive cutting teeth, making them effective for quick cutting in hardwoods. However, they require skilled handling and maintenance due to their tendency to dull quickly.
What is the difference between a 3/8 and a .325 chainsaw chain? The numbers 3/8 and .325 refer to the chain pitch. A 3/8 chain has a larger pitch, meaning the distance between drive links is greater compared to a .325 chain. Chains with different pitches are not interchangeable between bars and sprockets.
What is the maximum chain speed? The maximum chain speed varies depending on the chainsaw model and application. Generally, it’s around 100 feet per second (fps) for professional chainsaws and slightly lower for consumer models.
How do you calculate chain speed? Chain speed is calculated by multiplying the engine RPM by the chain’s pitch (distance between drive links) and dividing by a constant (usually 12 to convert inches to feet).
How do you check RPM on a chainsaw? You can use a tachometer, a tool designed to measure engine RPM, to check the RPM of a chainsaw. Attach the tachometer to the spark plug wire and start the chainsaw to get an accurate reading.
Can you use a .050 chain on a .043 bar? No, you cannot use a .050 chain on a .043 bar. The chain’s gauge (.050 or .043) must match the gauge of the bar to ensure proper fit and function.
Should chainsaw chains be 30 or 35 degrees? The choice between 30 and 35-degree angles for chainsaw chain teeth depends on the type of cutting you’ll be doing. Generally, a 30-degree angle provides a sharper cutting edge but may require more frequent sharpening.
What does the C stand for in a chainsaw? The “C” in a chainsaw model often indicates that it’s designed for occasional or consumer use, as opposed to “P” which stands for professional or “XP” for extra professional use.
Are all chainsaws 50 to 1? No, not all chainsaws use a 50:1 fuel-to-oil ratio. Different chainsaw models and brands may have varying recommended fuel mix ratios. Always follow the manufacturer’s guidelines.
What does S56 mean on chainsaw chain? “S56” is likely a code that represents a specific type or model of chainsaw chain. The exact meaning can vary based on the manufacturer’s labeling system.
What do chain numbers mean? Chain numbers often refer to specifications of the chainsaw chain, such as its pitch, gauge, and number of drive links. These numbers help identify the correct replacement chain for a specific chainsaw.
Does cutting wet wood dull a chainsaw? Yes, cutting wet wood can lead to faster chain dulling. Wet wood contains more moisture, which can increase friction and wear on the chain, leading to quicker dulling.
Why does my chainsaw chain dull so quickly? Several factors can contribute to rapid chain dulling, including hitting the ground or hard objects, cutting dirty or abrasive materials, incorrect filing angles, and using the wrong chain for the application.
What’s the most aggressive chainsaw chain? Full-chisel chains are often considered the most aggressive due to their sharp cutting teeth and faster cutting speed. However, they require more skill to operate and maintain.
What chainsaw chain do professionals use? Professional chainsaw users often use full-chisel chains for their aggressive cutting capabilities. However, the choice depends on the specific cutting tasks and the operator’s preferences.
What size chainsaw is best? The best chainsaw size depends on your intended use. Smaller chainsaws (12 to 16 inches) are suitable for light tasks, while larger ones (18 to 24 inches) handle heavier cutting.
What is the most common chainsaw chain size? The most common chainsaw chain sizes are 3/8″ pitch with a .050″ gauge or a .325″ pitch with a .050″ gauge.
Can I use a 10-speed chain on an 8-speed? No, a 10-speed chain is not compatible with an 8-speed drivetrain. The chain width and compatibility must match the gear system.
What is the most common single speed chain size? The most common single speed chain size is 1/8 inch width.
What is the recommended speed ratio for chain drives? The recommended speed ratio for chain drives depends on the application. Generally, a 1:1 ratio provides equal speed, while other ratios determine speed differences between the driving and driven sprockets.
What does 10-speed chain mean? A 10-speed chain refers to a bicycle chain designed for a bike with a 10-speed drivetrain. It has narrow plates to accommodate the closely spaced cogs.
What is the formula for calculating chain drive? The formula for chain drive calculation involves the number of teeth on the driving sprocket, the number of teeth on the driven sprocket, and the pitch diameter of the sprockets. The formula is: Speed Ratio = (Number of Teeth on Driven Sprocket) / (Number of Teeth on Driving Sprocket).
What does the speed of a chain mean? The speed of a chain, often expressed as chain speed, refers to how fast the chain travels along the bar of a chainsaw. It’s calculated by multiplying the engine’s RPM by the chain’s pitch.
What is the maximum RPM of a Stihl chainsaw? The maximum RPM of a Stihl chainsaw varies depending on the model and engine size. Professional Stihl chainsaws can reach RPM values of around 13,000 to 15,000.
What is the RPM of a Stihl saw? The RPM of a Stihl chainsaw varies depending on the model, engine size, and throttle setting. It can range from around 2,800 to 15,000 RPM.
How do I manually check RPM? To manually check RPM, you can use a tachometer, which measures engine speed. Attach the tachometer to the spark plug wire and run the engine at different throttle settings to get accurate RPM readings.
What is the difference between size 40 and 41 roller chain? Size 40 and 41 roller chains have different pitches (0.5 inch for size 40 and 0.625 inch for size 41). They are not interchangeable, and the sprockets and other components must match the chain size.
Can you put a different size bar on a chainsaw? Chainsaw bars must match the specific chainsaw model and its recommended bar length. You cannot arbitrarily put a different size bar on a chainsaw without proper compatibility.
Is Picco the same as low profile? Yes, Picco is a term used by Stihl to describe their low-profile chainsaw chains. They are designed to reduce kickback and are often used on homeowner chainsaws.
Do chainsaw chains need to be tight? Chainsaw chains need to be properly tensioned. They should have just enough tension to stay on the bar without sagging, but not so tight that they bind or restrict movement.
Should chainsaw chain be tight or loose? Chainsaw chains should not be too loose or too tight. The correct tension allows the chain to move freely but prevents it from coming off the bar during operation.
How do I know if my chainsaw is sharp enough? A sharp chainsaw should produce fine wood shavings while cutting. If you see dust or the chainsaw struggles to cut, it’s likely time to sharpen the chain.
