Sprocket and Gear Teeth Heat Treating

Heat treating teeth doubles the life of a sprocket and gear.  Typically the Rockwell hardness (Rc) of the teeth ranges from 30-63 Rc depending on the type of steel.

• Sprockets - The part's outside diameter is almost unlimited.  Any normal sprocket tooth can be hardened.
• Gears - The gear must be made from medium carbon / direct hardening steel.   2-1/2" wide face and smaller.
