What they don't teach you in engineering school about gear design

It’s this:

  1. The life of plastic gears can be calculated – just like metal gears.
  2. Plastic gears can replace metal gears in most open gearing applications.
  1. When designing gears for non-lubricated applications, the tooth root stress calculation is no longer sufficient.

Flank wear also has to be considered.

  1. A tooth profile modification can reduce wear.
  2. Plastic gears allow a unique way to eliminate backlash.


Only Power-Core “plastic-on-metal” gears give you all these advantages!

  • Fabricated to AGMA Class 9+   - machined to high accuracy.
  • Outer diameters from 1 inch to 3 feet and larger- handles a wide range of applications.
  • Precision-matched tooth geometry – tooth mesh designed to match application; gear material dimensionally stable.
  • Light weight – reduces inertia and drive power requirements.
  • Does not grow or swell in moisture – reduced backlash; suitable for wash down and sub-zero applications.
