The Browning H120R18 roller chain sprocket is a steel, single‑strand Type 4 drive sprocket for #120 chain with 18 teeth, designed for Browning split‑taper mounting (R1) and hardened teeth for wear resistance. It accepts bore sizes from 1-1/8 in to 3-3/4 in, enabling flexible shaft fitment, and provides an outer diameter of 9.407 in with a chain pitch diameter of 8.638 in, optimized for a 1-1/2 in pitch (#120) roller chain. This 18-tooth sprocket pairs with standard Browning components to deliver reliable power transmission in drives that require split‑taper bushings and steel construction.
