Oregon 280RNDD009 .050" Gauge 3/8" Pitch 28" Power Match Bar, White

What It Is

This is a 28-inch, .050-gauge, 3/8-pitch Power Match replacement chainsaw bar from Oregon, designed for medium-duty cutting on EGO battery-powered chainsaws. It’s a direct-fit upgrade or replacement bar for models requiring a 28” bar length.

Fitment & Compatibility

Before buying, confirm your saw’s bar mount pattern. This bar uses the Power Match system (Oregon’s universal mount), which fits many EGO cordless chainsaws, but not all. Check your owner’s manual for bar mount type—typically “K095” or “Oregon 80” mount. Also verify:

• Bar length: Must match your saw’s max bar length (e.g., EGO CS1804, CS2000 use 28” bars).
• Gauge & pitch: Your chain must be .050” gauge and 3/8” pitch. Using a different gauge chain will not fit the bar groove.
• Nose sprocket: This bar has a replaceable sprocket tip. Ensure your saw’s chain tensioner and oiler align with the bar’s oil holes (standard Oregon pattern).

If you have an older EGO model or a non-EGO saw, measure your current bar’s mount slot (width, length, and oil hole position) and compare to Oregon’s Power Match specs.

Key Things to Know

• Quality: Oregon is a top-tier aftermarket brand. This bar is durable, with a hard-faced steel body and a sealed bearing sprocket tip that outlasts cheap OEM bars.
• Installation: Easy—just swap bars, adjust chain tension, and check oil flow. No special tools needed. Ensure the bar studs fit snugly.
• Common gotcha: The .050” gauge is thinner than standard .058” or .063” bars. Double-check your chain’s gauge before buying. If you have a .058” chain, this bar won’t work.
• Chain compatibility: 3/8” pitch chains with .050” drive links (e.g., Oregon 91V or 91PX) are required. Your existing chain may not fit if it’s a different pitch or gauge.

Should You Buy It

Yes, if you own a compatible EGO 28” chainsaw and want a reliable, long-lasting bar that outperforms many OEM options. It’s ideal for homeowners and light commercial users who need a drop-in replacement without paying dealer prices. Skip it if your saw uses a different bar mount or chain gauge.
