How-to: Bar and Chain Fit-Up

*You can find the parameter on your old saw chain package or the stamp on your guide bar. If you still cannot find them, you must measure the values manually.

How to measure?


  • Bar length: Determine guide bar length by measuring from the base of the guide bar to the tip of the bar.
  • Chain Gauge: Chain gauge is the thickness of each drive link. Find your gauge by measuring the section of the drive link inside the groove of the guide bar.
  • Chain Pitch: Pitch is the distance between drive links. Measure pitch by counting three links in a row and dividing by two.
  • Drive Links: Count each drive link to know the total number of drive links on your saw chain.

Raw Materials

Raw Materials


  • The raw materials of the main components of the UPFOREST sawchain are directly imported from Germany. This is different from other manufacturers in that they only use imported raw materials in some of the parts, or even do not use imported raw materials.
  • The raw materials of cutters, drive links, tie straps are called 68CrNiMo, rivet is called GCr15, which is the same raw material used by Stilh.
  • Each batch of raw materials has a product quality inspection report, and passes through our quality inspection department to ensure that our saw chain has the best performance.
