Husqvarna X-Tough 20 RSN 3/8" 1.5 SM 72DL Forged Bar

Husqvarna X-TOUGH™ RSN (Replaceable Sprocket Nose) bars offer increased durability and reduced maintenance. Featuring a solid steel body with increased guide hardness and an optimized oil hole, the RSN bar design ensures high productivity. Load is transferred to a high-quality roller bearing with support shields, resulting in reduced friction and longer life. The patented, robust shape of the RSN and the three-rivet attachment provide high durability and make the bar less susceptible to abuse. A replacement bar tip is available as a spare part.
