Greenworks 18" Chainsaw Bar & Chain Combo – 3/8" LP Pitch, 0.05" Gauge, 62-Link Replacement

Greenworks 18" chainsaw bar and chain combo is a genuine replacement assembly engineered to restore cutting performance for compatible Greenworks 18" chainsaws.

When a worn bar or dull chain slows your yard work, swapping in an original-equipment Greenworks 18-inch bar and 62-link chain brings back reliable cutting, safer operation, and consistent fitment. This kit matches the factory specifications — 3/8" low-profile pitch and 0.05" gauge — so it installs easily on supported Greenworks models and helps you tackle pruning, limb cleanup, and light felling with the intended tension and bar alignment.

Which Greenworks saws will this bar and chain fit?

This 18" bar and 62-drive-link chain is designed as a replacement for specific Greenworks chainsaw models and other saws that use 3/8" LP pitch, 0.05" gauge, and 62 drive links. Always check your saw’s manual or existing chain markings to confirm compatibility before purchasing.

• Direct replacement for Greenworks model numbers such as GCS80450, GCS80420, and 20332.
• Fits saws requiring an 18" bar, 3/8" low-profile pitch, 0.05" gauge, and 62 drive links.
• Not suitable for saws with different pitch, gauge, or drive-link counts.

How does the low-kickback design affect use and safety?

The chain in this combo is manufactured with low-kickback geometry to reduce the chance of sudden snatch during operation, helping you maintain control when performing everyday cutting tasks. Reduced vibration and lower kickback characteristics make longer sessions more comfortable and lower user fatigue.

• Low-kickback cutters help limit reactive forces that can cause loss of control.
• Lower vibration profile improves comfort during repetitive cuts.
• Still requires standard safe cutting practices and protective gear.

What should I know about installation and maintenance?

Installing this Greenworks bar and chain is straightforward with basic tools; tensioning, lubrication, and periodic sharpening are essential to preserve cutting performance and extend component life. Follow the saw manufacturer’s instructions for correct tension, proper chain oiling, and torque settings.

• Fit the bar, loop the chain, and set correct chain tension according to your owner’s manual.
• Use recommended bar and chain oil, and check oiling system flow before each use.
• Sharpen or replace the chain when cutting efficiency drops or cutters are damaged.

What are the technical specifics and performance benefits?

The combo contains an 18-inch bar sized to the chain’s 62 drive links; the 3/8" low-profile pitch and 0.05" gauge match Greenworks factory tolerances, ensuring smooth engagement with the drive sprocket and stable rail support. This preserves the saw’s cutting dynamics and helps avoid premature wear caused by improper fitment.

• Bar length: 18 inches — suitable for medium pruning and small felling jobs.
• Chain specs: 3/8" LP pitch, 0.05" gauge, 62 drive links for correct sprocket mesh.
• OEM part helps maintain intended bar alignment, chain tension, and oiling characteristics.

Who this is for: This Greenworks 18" chainsaw bar and chain combo is for homeowners, landscapers, and maintenance pros who own compatible Greenworks 18" chainsaws and want an authentic replacement part that restores factory fit and cutting behavior. Choose this kit if you value correct specifications, low-kickback performance, and easier maintenance between sharpening cycles. If your saw uses a different pitch, gauge, or drive-link count, verify compatibility or consult Greenworks support before ordering.
