This is the feeder gear that pushes filament inside the extruder on Creatbot F430, PEEk300, D600 Pro v1, & F160 series 3d printers.
These cogs are made of hardened nickel stainless steel composite for optimum durability without being brittle.
Most cheaper black feeders are made of carbide steel that can crack teeth & cause a jam in the hot end.
This drive gear is mounted on the stepper motor inside the head.
It is the cog that grips the filament & pushes it down the heat brake towards the hot end.
Needs to be changed after a while when its teeth start to wear.
Will wear more if using lots of Carbon or Glass Filled filaments.
