Chainsaw Facts - Did You Know That....

A chainsaw piston goes up and down in the cylinder 20,000 times per minute.

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 ).

The drive links impact the sprocket an average of 1,300 times per second.

The chainsaw bar sprocket rotates nearly 1 million times daily when sawmilling so grease that sprocket daily .

The higher the chain speed, the faster the sawmilling speeds and to calculate this:

Take the chain pitch and multiply by 2. Multiply the above number by the number of teeth of the saw sprocket.
Multiply that number by the saw R.P.M.
The final answer will be the chain speed in inches per minute, just divide by 12 to convert to feet per minute.
