Overview
This 2-pack of aftermarket 18-inch replacement chains is designed to fit select Atlas chainsaw models. When the factory chain wears out, loses its edge after multiple sharpenings, or stretches past the tensioner’s range, this chain gets you back to cutting without waiting for a dealer order. It’s built to OEM dimensions for a direct fit.
Key specifications
- Bar length: 18”
- Pitch: 3/8 LP
- Drive links: 62DL
- Quantity: 2-pack
- Type: Semi-chisel (aftermarket replacement)
Compatibility
This chain is manufactured as a direct-fit replacement for select Atlas chainsaws listed in the compatibility section above. Always cross-check the pitch, gauge, and drive-link count stamped on your current bar before ordering — even within the same brand, different models can require different chain specs.
Installation notes
Disconnect power before any chain work. Remove the bar cover to access the sprocket and bar. Take note of the cutter direction, then remove the old chain. Place the new chain in the bar groove with cutters oriented forward on the top rail. Loop it onto the drive sprocket, replace the cover, and turn the tension adjuster until the chain sits snug with minimal sag. Spin the chain by hand to confirm it moves freely.
Common questions
Q: Will this 2PC replacement saw chain fit my ATLAS 80V cordless chainsaw model 56937 with an 18” bar?
Yes, this chain is made for the 18” ATLAS 80V cordless chainsaw model 56937 and matches the required 3/8” low-profile pitch, .050” gauge, and 62 drive links. As long as your saw is still using the stock 18” bar, these chains should fit correctly.
Q: How do I confirm this is the right chain if my old chain markings are worn off?
Check the bar stamp or your saw’s manual for the chain specs: 3/8 LP pitch, .050” gauge, and 62DL for an 18” bar. If those match your ATLAS 56937 setup, this replacement chain is the correct size and type.
Q: Do I need to do anything special when installing or maintaining these 18” 3/8LP saw chains?
When installing, make sure the cutter teeth on the top of the bar face forward and then adjust tension so the chain sits snugly but still pulls around by hand. Keep the chain properly oiled, recheck tension after the first few cuts, and touch up the cutters regularly to help it cut smoothly and reduce wear on the bar and sprocket.
