Gears are the most commonly found transmission parts. In a typical gear assembly, one toothed steering wheel interlocks with another. Gearboxes are often used to deliver power or switch direction.
plastic worm gear plastic gears, as the name suggests are made of plastic instead of metal. Included in these are worm gears, spur gears, helical gears, pinion gears, tooth gears, bevel gears, and planetary gears. The materials can be a combo of Nylon (Nylon PA6 or Nylon PA66) and POM (Polyoxymethylene).
Advantages of Plastic Gear:
They can easily can be found in various shapes.
Plastic-type gears are relatively low cost.
They produce lower noise in comparison to metal gears.
They are resistant to wear and tear as they have low friction coefficient.
Lightweight
Resistant to corrosion 
Self-lubricated
These gears are used extensively in various power transmission and motion control systems. Though we’ve listed simply five types of plastic material gears, we also provide customized gears according to client’s specifications.
