Stens sprocket nose bars combine exceptional strength with light weight for your chainsaw. Heat treated steel delivers strength for durability and long service life, while lighter weight reduces operator fatigue from handling a chainsaw. The bar is designed to maximize the speed at which the chain moves, which boosts the efficiency of the chain’s cutting action. When choosing a sprocket nose bar, you’ll have a choice of ones with either a replaceable or hard nose. The replaceable version provides the option to replace only the nose if it becomes damaged or worn. This benefit offers a cost-saving advantage as opposed to replacing the entire bar. The replaceable nose version also provides additional adaptability when changing the pitch of the chain. The hard nose version is a complete piece of metal to the nose, which is preferred when the bar needs extra sturdiness due to more difficult conditions. Stens sprocket nose bars meet the standards required by professional arborists.
