Husqvarna 505303661 Rim 3/8" - 8T

Cutting through rebar-reinforced concrete slabs demands reliable power transmission from your chainsaw, and this rim sprocket delivers consistent performance in demanding demolition work. The 3/8-inch pitch with 8-tooth configuration provides the standard drive ratio for professional-grade concrete cutting chains. This replacement rim fits Husqvarna concrete cutting saws and allows you to swap out worn sprockets without replacing the entire drum assembly, reducing downtime on the jobsite. The hardened steel construction handles the stress of cutting through aggregate and reinforced materials. Regular sprocket replacement maintains proper chain speed and prevents premature chain wear that can slow your progress. Built for concrete cutting contractors and demolition crews who need dependable replacement parts that keep their equipment running through high-volume cutting operations.
