Husqvarna 599303272 Chainsaw Guide Bar 18in .325 .050 72DL

Product Description

The HUSQVARNA 599303272 is an OEM replacement chainsaw guide bar designed for professional-grade and residential chainsaw applications. This 18-inch bar is machined from high-strength steel and spec'd for .325-inch pitch chains with a .050-inch gauge groove and 72 drive links. The bar maintains precise chain alignment throughout the cut, reducing wear on both the bar and drive sprocket. Licensed HUSQVARNA technicians and experienced chainsaw operators use this bar as a direct factory replacement when an original bar shows wear, damage, or kerf deformation.

This guide bar suits chainsaws operating in residential yard maintenance, light land clearing, and firewood processing. The 18-inch cutting length is a common working length for mid-displacement saws handling timber up to roughly 16 inches in diameter. Installation is straightforward for any technician familiar with bar and chain service procedures. Compatible models cited in product data include the Husqvarna 450 Rancher and 445, as well as select Husqvarna models accepting an 18-inch bar with .325-inch pitch and .050-inch gauge chain.
