The gears made of the tribologically optimised iglidur high-performance polymers prove that a significantly longer service life is possible over gears made of commercially available plastics. Due to fine-tuned additives of reinforcement materials and solid lubricants, they do not require additional lubrication. Our plastic gears can be used in various applications.
Our product range
In our gear shop, you can purchase various types of plastic gears with no minimum order quantity. Here you will find spur gears, gear racks, bevel gears and angled gearboxes.
Gears brochure and samples
The gears made of iglidur high-performance polymers enable lubrication-free and maintenance-free use.
Thanks to their special combination of base polymers, fibres, fillers and solid lubricants, they are extremely wear-resistant. Our gears have already successfully proven themselves in different applications.
The iglidur materials are put through their paces in our own test laboratory.
In accordance with the parameters in your application, we provide you with free advice on the right material and manufacturing and tool technology needed to make your individual gear (toothed component) in a reliable process without obligation.
You can place an order with igus without any minimum order quantity.
Our CAD database
Our CAD library makes work much easier for all designers.
Here you can create CAD models of our gears and gear racks, download them in various file formats and even transfer them directly to your CAD program.

Application examples with polymer gears
That's why we developed 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.
Your questions and our answers (FAQ)
What is a gear?
The gear is a round component with uniformly distributed teeth around its circumference. It is used to transmit power between two rotating gears or between a gear and a gear rack. Other types are used depending on the application.
What types of gears are there?
The most common types of gears/gearing components are
spur gearsgear racks* worm gears
bevel gears
Different kinds of gear and toothing are often combined with each other to produce certain motion sequences.
When do gears fit together?
For gears to move smoothly, it is important that the teeth can mesh with each other. To achieve this, the teeth of the gears must be the same size and therefore have the same module. This applies to all gearing components, e.g. also for gear racks, bevel gears, etc.
What is the module of a gear?
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.
How long does a gear last?
The service life of a gear depends on various factors. Firstly, which specification (e.g. module or number of teeth) the gear has and how the gear is used (e.g. application temperature, torque or speed).

How are the gears made from the iglidur® high-performance polymers?
At igus, gears are manufactured using three production processes:
- Injection moulding with iglidur® granules
- Mechanical processing from iglidur® bar stock
- 3D printing with iglidur® SLS or FDM materials
Depending on your enquiry, we will advise you free of charge and without obligation with regard to production in order to find the most economical solution together with you.
How are the iglidur® gears tested?
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.
What is the minimum order quantity?
There is no minimum order quantity for our gears. You can request and order any quantity from 1 upwards.
Can the iglidur® gears be lubricated?
External lubrication of the gears is not necessary. All the materials we use are already tribologically optimised and designed for dry operation. However, if lubrication is required, this is possible in conjunction with a silicone-free lubricant.
I need a special type, is this possible?
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.
What are the advantages of iglidur® gears?
The iglidur® 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 quiet and offer optimum emergency running properties. The tribological optimisation of the materials also results in a low coefficient of friction.
When does a gear need to be replaced?
As soon as the gear is no longer able to transmit power due to wear, it must be replaced. By making geometric adjustments such as module, number of teeth or by selecting the right material, the service life of the gear can be increased.
What areas of application are there?
The iglidur® gears are used in all industries. Depending on the area of application, we offer special materials which, for example, are FDA-compliant or meet certain fire standards (e.g. the automotive sector) or similar.
