Wear-resistant plastic gears

A plastic gear is a round component that has uniformly distributed teeth around its circumference. It transfers force between two rotating gears or between a gear and a rack. Depending on the application, further types are used.

The most common kinds of pinion gears are:
• Spur gears (you can find them in our online shop)
• Racks
• Worm gears
• Bevel gears
Different kinds of gear and toothing are often combined with each other in order to implement certain sequences of movement.

At igus®, gears are made with the help of three manufacturing methods:
• Injection moulding with iglidur® granulate materials
• Mechanical processing with iglidur® bar stock as the material
• 3D printing with iglidur® SLS or FDM materials
Depending on the enquiry, we will advise you on manufacturing methods and work with you to find the best economical solution

The module indicates the size of a gear. The module is calculated by dividing the pitch circle diameter by the number of teeth (m= d/z).
Please note that only gears with the same module can be combined.

Yes, the production of special geometries is possible and can be realised for all quantity scenarios thanks to our diverse manufacturing processes. We will be happy to advise you individually on your special geometry and the appropriate material. You can request your customised gear here 

The iglidur® gears are used in all industries. Depending on the area of application, we offer special materials which, for example, have FDA conformity or certain fire standards (e.g. the automotive sector) or similar.

Our  gears require no external lubrication and are therefore maintenance-free. With our gears, you also benefit from a long service life thanks to wear-resistant materials, which we achieve through the formulations of the iglidur® materials. Compared to metal gears, plastic gears are low-noise and offer optimum emergency running properties. The tribological optimisation of the materials also results in a low coefficient of friction.

We have test rigs in our test laboratory to test our gear made from a wide range of iglidur® materials in various scenarios. We are also happy to provide you with samples for your application-related tests.
