Dominant Ceramic Hybrid 6203 Main Bearings

  • $ 100.00
  • Save $ 20.00


NEW! We just got our 6203 bearings made, and are excited to get them out to you.

Your build is never complete unless you know what's inside the case. The bearings and the piston take the majority of the abuse in your saw. And, resisting heat build up cut after cut is a saw's fountain of youth.

Hybrid ceramic mains blend the best of both worlds, optimum durability and unequivocal performance. We spec these bearings with chrome steel outer races because we know the outers take the brunt of the force when you put them in. The balls, however, are Si3N4 ceramic. Ceramic balls are 70% smoother than steel, spec'd to ABEC-5 tolerance, and good for rpm well past the mid 30's. This is the most badass chainsaw bearing on the market.

Ceramic balls, when compared to chrome steel balls:

  • 60%+ lighter
  • 50%+ stiffer
  • 70%+ smoother
  • More than 100% better rolling contact fatigue life
  • Much, much, harder than steel balls

Stainless steel bearing retainers round out the package. Overall friction is more than 10% less than an all-steel bearing of the highest quality. On our 6202 hybrid bearings, we've seen an increase in 500 free rpm on a Husky 357. This translates into speed in the wood, under load.

This the known list of what these bearings will fit. "Credited" to Scott at  www.chainsawr.com If you don't see your bearing listed in the drop-down menu, just select a saw of similar displacement. We are mainly just trying to keep track of what saws these are going in. Some of these saws take 1 and some take two of these 6203. Please be responsible and make sure you order the right number for your saw.
