Browning 40P18 Split Taper 18 Tooth Machined Sprocket

Browning 40P18 Split-Taper Sprocket is a precision steel sprocket for 40-series roller chain drives, delivering 18 teeth and a split-taper mounting (P1) for easy installation and removal on standard shafts. Designed for a 1/2-inch chain pitch (chain size 40), this sprocket features hardened teeth for wear resistance and a robust, durable construction typical of Browning split-taper offerings. Its geometry yields a pitch diameter of 2.879 inches and an outer diameter of about 3.14 inches, making it a compact, exact-fit option for small-to-midsize drives. The 40P18 works with Browning’s P1 bushings to accommodate a range of bore sizes, enabling secure mounting on a variety of shafts in industrial power transmission systems.
