Wear-resistant polymer gears

From a single part to high-volume production of up to several millions

Gears made of iglidur® high-performance polymers enable lubrication-free and maintenance-free use.
Thanks to their special combination of base polymers, fibres, extenders and solid lubricants, they are extremely wear-resistant. Our gears have already successfully proven themselves in different applications.
iglidur® materials are thoroughly tested in our own Testlab.
In accordance with the predominant parameters in your application, we provide you with free, non-binding advice on the right materials and manufacturing and tool technology needed to form your individual gears (toothed component) in a reliable process.
You can place an order with igus® with no minimum order quantity.

Application examples with polymer gears


Why we developed our gears

iglidur® gears have proven their worth in different gearboxes and have also been tested under realistic conditions of use in the igus test laboratory. For example, torque fluctuations, efficiency and backlash of the gearboxes with polymer gears are electrically measured and evaluated. The gathered empirical values allow for continuous optimisation of our gears and use in wear-intensive continuous application.
iglidur® gears are characterised by their special wear resistance in use. Due to their special material composition of base polymers, fibres, fillers and solid lubricants, they have very low wear properties and do not require additional lubricants. This extends maintenance intervals and reduces expensive downtime minutes.

Frequently asked questions about gear pinions

What is a gear pinion?

A gear pinion 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. 

What kinds of gear pinions are there?

The most common kinds of gear pinions 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.  

How are the gear pinions made from plastic?

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 – free of charge, no strings attached.

Polymer gear instead of metal gear

Tech up and cost down - now

Polymer gears are cost-effective, do not require external lubrication and are maintenance-free.
In contrast to metal gears, our polymer gears contain solid lubricants, which reduce friction. Furthermore, certain fillers ensure an additional improvement of the mechanical properties.
Overview of benefits

  • Lubrication-free
  • Maintenance-free
  • Lightweight
  • Noise-reducing
  • Corrosion-free
