Husqvarna 585639072 Chainsaw Chain 20 Inch .050 Gauge

Product Description

The HUSQVARNA 585639072 is a 20-inch replacement chainsaw chain designed for professional-grade cutting performance. Built to the S83G specification, this chain runs on a 3/8-inch pitch and a .050-inch gauge, with 72 drive links to match the correct bar length. It is a direct-fit replacement chain intended for use by arborists, forestry professionals, landscapers, and experienced operators who need a reliable, ready-to-run chain without modification. The S83G designation indicates a semi-chisel cutter style, which balances cutting speed with durability in dirty or abrasive wood conditions.

This chain is suited for residential and light commercial chainsaw use where a 20-inch bar is standard. The 3/8-inch pitch and .050-inch gauge are among the most common specifications across a wide range of mid-to-large displacement gas-powered chainsaws. Typical applications include felling, limbing, bucking firewood, and land clearing. It is designed for operators who require a replacement chain that meets OEM specifications without the need for custom fitting or modification.

Key Features

• 20-inch chain length matches standard 20-inch guide bars
• 3/8-inch pitch for compatibility with a broad range of drive sprockets
• .050-inch gauge fits standard .050 bar groove tolerances
• 72 drive links for precise bar-length matching
• S83G semi-chisel cutter profile offers durability in abrasive cutting conditions
• OEM replacement specification — no modification required for correct-fit installations

Compatibility

Designed as an OEM-style replacement chain for chainsaws requiring a 20-inch bar with 3/8-inch pitch, .050-inch gauge, and 72 drive links. Verify pitch, gauge, and drive link count against the existing bar and sprocket before installation.

Installation Notes

Chain installation should be performed by a qualified operator with the saw powered off, the ignition disabled, and cut-resistant gloves worn at all times when handling the chain. Ensure the drive links seat fully into the bar groove and sprocket before tensioning. After tensioning, rotate the chain by hand to confirm it moves freely without binding. Always follow the saw manufacturer torque guidance for bar nuts and re-check tension after the first few cuts, as new chains stretch during break-in.
