Browning H4017X3 Sprocket Wheel Assembly 40 Teeth

Browning H4017X3 is a finished-bore sprocket for No. 40 chain drives, featuring 17 teeth and a 3/4" bore size. Designed for 40-chain (1/2" pitch) power transmission, it provides a 2.721" pitch diameter and an overall outside diameter of 2.96" in steel with hardened teeth to resist wear in demanding service. The bore is finished for straightforward mounting on a compatible shaft, aligning with Browning’s family of finished-bore sprockets to facilitate easy replacement in existing installations. The 17-tooth geometry is tailored to deliver a specific gear ratio when paired with the appropriate driver or driven components, making it suitable for medium-duty drive applications that use No. 40 chain. When replacing or upgrading, ensure the chain size (No. 40) and bore size (3/4") match your current setup to maintain proper chain engagement and alignment. This model is part of Browning’s extensive line of steel, hardened-tooth sprockets designed to extend service life in modular drive assemblies that rely on standard Browning bushings and adapters.
