Husqvarna X-TOUGH RSN (Replaceable Sprocket Nose) bars are our toughest sprocket nose bars. Thanks to the design, characterized by a solid steel body with increased rail hardness and the optimized oil hole, the maintenance effort are reduced, and high productivity can be achieved. The load is transferred to the high-quality roller bearing with supporting shields, resulting in less friction and a prolonged lifetime. The robust and patented RSN shape and the triple-rivet mount offer high durability and make the bar less sensitive to abuse. A replacement tip is available as a spare part.
