The LiftMaster 71-1550B50LKH Sprocket Kit is a precision-engineered 50-tooth drive sprocket designed for LiftMaster operator systems that utilize a 1" shaft with a 3/8" keyway. The larger tooth count supports smooth power transmission and controlled chain movement in heavy-duty and high-load applications.
Built for durability in commercial and high-cycle environments, this sprocket helps maintain proper drive alignment while reducing wear on chains and related components. Replacing worn sprockets with the correct bore size, keyway, and tooth count supports efficient operation and long-term reliability of the operator drive assembly.
