Wear-resistant polymer gears
From a single part to high-volume production
The gears made from the tribologically optimised iglidur high-performance plastics impress with a significantly longer service life than gears made from 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 catalogue range
In our gear shop, you have the option of buying different types of plastic gears with no minimum order quantity. Here you will find spur gears, gear racks, bevel gears and angular gearboxes.
Gears brochure and samples
The gears made of iglidur high-performance plastics 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.
The iglidur materials are put through their paces in our in-house 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 easier for all designers.
You can create CAD models of our gears/gear racks here, download them in various file formats and even import them directly into your CAD program.
No registration is necessary.

Application examples with polymer gears
This is 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.
Your questions and our answers (FAQ)
What is a gear?
A gear is a round component with evenly distributed teeth around its circumference. It is used to transmit force between two rotating gears or between a gear and a gear rack. Depending on the application, further types are used.
What types of gears are available?
The most common types of gears/gear components are:
- spur gears
- Racks
- Worm gears
- Bevel gears
Different gear and toothing types are often combined with each other to realise certain motion sequences.
When do gears fit together?
In order for gears to move easily, it is important that the teeth can mesh with each other. For this, the teeth of the gears must have the same size and therefore the same module. This applies to all gear 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).
It should be noted 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. On the one hand, the specifications (e.g. module or number of teeth) of the gear 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 manufacturing processes:
- Injection moulding with iglidur® granulates
- Mechanical machining 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 regarding production in order to find the most economical solution together with you.
How are the iglidur® gears tested?
In our test laboratory, we have test rigs to test our gears made of the various iglidur® materials in different scenarios. We are also happy to supply 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 enquire and order with no minimum order quantity.
Can iglidur® gears be lubricated?
External lubrication of the gears is not required. All of the materials we use have been tribologically optimised and designed for dry operation. If you should want to lubricate, however, you can do so in combination with a silicon-free lubricant.
I need a special type, is this possible?
Yes, the production of special geometries is possible and feasible for all quantity scenarios due to our wide range of manufacturing processes. We would be happy to provide you with individual advice on your special geometry and the appropriate material. You can request your customised gear here.
What advantages do the iglidur® gears offer?
The iglidur® gears do not require any external lubrication and are therefore maintenance-free. In addition, you benefit from the long service life of our gears, which is due to wear-resistant materials, which we achieve with the formulations of 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 have to be replaced?
As soon as power transmission is no longer possible due to wear on the gear, they must be replaced. Through geometric adjustments such as module, number of teeth or by selecting the right material, the service life of the gears can be increased.
What are the available areas of application?
The iglidur® gears are used in all industries. Depending on the area of application, we offer special materials that, for e.g., have FDA conformity or certain fire standards (such as the automotive sector), or similar criteria.
Polymer gear instead of metal gear
Tech up and Cost down now
Plastic gears are cost-effective, require no external lubricants and are maintenance-free.
In contrast to metal gears, our plastic gears contain solid lubricants that reduce friction.
Furthermore, certain fillers provide an additional
improvement of the mechanical specifications.
