The piston ring speed on the average chainsaw travels 2,500 surface feet per minute. A chain slides across the surface of the sawbar rail at around 5000 feet per minute. The chain is moving at 55 to 60 m.p.h. or a mile per minute (88 feet per second).
Posts: 3,090. I actually adjusted my chain yesterday it was way to loose. While riding it was tapping the chain guard and was making the tapping noise while between 4k rpms and 5k rpms. No noise now I have about 15k miles on it but there's no real way of telling how long a chain is gonna last u. It all depends on how well you take care of it I've had the chain for 2 yrs now and next year or should I say for my winter project I think I'll be buying and installing a new one.
