Description
This spur (differential) gear is precision made using injection molded POM (Polyoxymethylene aka Delrin or Acetal).
POM is the perfect material for gears as it has high mechanical strength and rigidity, toughness and high resistance to repeated impacts and long-term fatigue endurance.
It also has excellent resistance to moisture, gasoline, solvents, and many other neutral chemicals.
Bottom line is that this is the right material for gears over what other makers are using such as Nylon or ABS plastic. Not to mention these are super quiet.
