Walk into a big-box hardware store, and you will see blister packs labeled "Universal 18-Inch Chain." They claim to fit Stihl, Husqvarna, and Echo.
In the world of precision engineering, "Universal" is a lie. A chain that fits everything fits nothing perfectly.
1. The Drive Link Count Reality We have said it before, and we will say it again: Bar length is a marketing term.
-
The Conflict: An 18-inch Stihl bar usually requires 66 Drive Links. An 18-inch Husqvarna bar usually requires 72 Drive Links.
-
The Universal Fail: A "Universal" chain might come with 68 links to try and split the difference, or use a generic gauge.
-
The Result: If you put a 72-link chain on a Stihl bar, the tensioner will max out before the chain is tight. The chain will hang loose, creating a lethal safety hazard. If you put a 66-link chain on a Husky, it won't even mount.
2. Matching Mass to Torque Generic chains often use a standard "chassis" weight. This is fine for a 60cc farm saw, but it kills the performance of a 40cc homeowner saw.
-
The Alpine Advantage: We offer Narrow Kerf (Pixel) options for smaller saws. These chains remove less wood (a narrower cut), which requires less horsepower.
-
The Physics: By fitting a specific Narrow Kerf chain to a small saw, you liberate horsepower. The saw maintains higher RPMs, cutting faster and cooling better. A "Universal" chain is a heavy anchor that bogs your engine down.
3. The Bespoke Standard At Alpine Chain Co., we do not sell blister packs. We cut from bulk industrial reels to the exact Drive Link count your machine requires.
-
Stihl 026? You get.325 pitch,.063 gauge, 67 links.
-
Husqvarna 455? You get 3/8 pitch,.058 gauge, 68 links.
Don't settle for "close enough." Your chainsaw operates at 13,000 RPM. You want a custom fit.
Measure your bar. Count your links. Order the Alpine Standard.
