Husqvarna 18″ Sprocket Nose Chainsaw Bar X-Tough HT258-72 OEM #596689872

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 is 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 prolonged lifetime. The robust and patented RSN shape and the triple-rivet mount offers high durability and makes the bar less sensitive to abuse. Replacement tip is available as a spare part.
