Browning H4019X3/4 is a finished-bore, single‑strand roller chain sprocket designed for No. 40 chain. It features 19 teeth and a 3/4 in bore, compatible with 1/2" pitch drives, and is built from steel for durability in mid-duty industrial and agricultural applications. The sprocket’s outside diameter is 3.3 inches and its pitch diameter is 3.038 inches, providing reliable tooth engagement and torque transfer in compact drive setups. With the finished bore, this Browning part arrives prepared to install at the exact bore size, enabling quicker assembly in equipment such as conveyors, farm machinery, or general machinery that use Browning No. 40 chain. The H4019X3/4 designation identifies a 19‑tooth, 3/4" bore configuration, a common choice when a precise, compact sprocket is needed to fit space-constrained drives and maintain consistent chain alignment and performance.
