Husqvarna X-Tough 20-Inch Bar RSN | 3/8-inch Pitch, .050-inch Gauge, 72 Drive Links

Meet the Husqvarna X-Tough 20-Inch RSN Bar

In professional forestry and heavy-duty woodwork, the X-Tough RSN Bar stands out for durability and predictable performance. Its solid steel body, hardened rail, and optimized oil channel work together to reduce friction and keep the bar running smoothly through long workdays. The design also transfers load efficiently to the roller bearing with protective shields, helping components stay cooler and last longer under demanding cuts.

The heart of the RSN system is its replaceable sprocket nose. When wear occurs at the nose, you can swap it out quickly, minimizing downtime, and you can order a spare tip as a ready-to-go replacement. The triple-rivet mount provides a robust anchor that resists flex and misalignment in tough environments.
