Gear Rod Stock
Machine your own gears to fit the exact face width and shaft diameter required. Rod stock has teeth with a 20° pressure angle, the current industry standard. 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Teeth are not hardened so you can machine and harden them to fit your application. Hardening a gear’s teeth increases its wear resistance. Also known as spur gear rod stock.
For gears to mesh correctly, they must have the same pressure angle and pitch.
