Chainsaw bar ?

Will any brand bar work successfully with a stilh ms 250c , thanks for your response

Beand doesn’t matter but it needs to match your saw/chain specs.

Bingo.

Confirming, any brand bar will work, but it has to match the length of your chains AND it has to be the correct gauge. The gauge is a measurement of the width of the drive links of the chain, or to say it another way, it’s a measurement of the width of the groove that runs down the middle of the bar.

You need the correct bar, in the right length (16 inch, 18 inch, etc) and in the correct gauge. .050 is the most common gauge out there, but you need to know for sure.

The Stihl MS250 has the Stihl “small mount” pattern for mounting the bar. It uses .325″ pitch sprockets, and the kerf, (the slot in the bar the chain rides in) is .063 inches. Any bar with these specifications will fit. The chain will have to be the right length for the bar you choose, and the MS250 typically uses an 18 inch bar with a 68 link chain – bars actually longer than 18 are uncommon in the “small mount” pattern, bars that claim 18″ or longer, may not actually be the full claimed length. The MS250 is reputed to have a good amount of torque so it will pull a more aggressive profile chain nicely in soft wood, but probably not in hardwoods – pick your chain profile accordingly.

As a point of order, the kerf is the width of the cut made by the teeth. .063 is the gauge, which is the width of the drive links.

This kind of chain saw. Just kidding.

This thread reminds me of a phone call I sat through with my IT guy and a software vendor a long time ago. I didn’t understand a thing they talked about. When the call was over my IT guy said “we’re all good.” All I could say was ok.

The bar has to be made for that model saw, my husky 455 and 372 don’t use the same one as the chain tensioner is located in a different place

Have to look at the tensioner pattern. I run different bars on my Husqvarna and stihl then what they say I can. I will have to look when I get home at what they are

Grouse, you are 100% correct. I knew there was a term for the drive tooth width, and kerf popped in my head.

So James O Wade, you need a bar with the Stihl “small mount” pattern (where the bar attaches to the saw body), a .325″ pitch, and a .063″ gauge, and the chain needs the correct number of links for that particular bar.
