Wolf Kunststoff-Gleitlager GmbH

Wolf 50Jahre clean

50+ years of experience

Our company now offers over 50 years of experience in the production, development and processing of high-performance plastics.

According to requirements, no more and no less – w/o unnecessary safety properties

The company was founded based on this credo by Mr. Wilfried Wolf in the late ’60s. He began to fill up both knowledge and far-sightedness gaps present in the high performance & engineering plastics market merging customer support in materials selection to the sales of stock shapes.

Few years later, the company area was expanded introducing the machining departmenttribological tests on materials were introduced (1972) in the brand new laboratory and the volume production was started by injection moulding. In the late ’80s the company invests in the first extrusion and compounding lines focusing on the manufacturing of the new developed ZEDEX® materials.

After these first important steps, the company Wolf took its flow and was continually improved and expanded over the years, and since the beginning of this century Mr. Gunter Wolf, son of Mr. Wilfried Wolf, has expanded the manufactoring area and improved the laboratory with test benches, mechanical and thermal analyses.

Cross-process Know-How and responsibility from a single source is the base of our success and one of the very great advantages we offer to our customers.

Our mission

Fun and passion in developing new materials,
to exceed current feasibility limits.

Cross process Know-How and Responsibility in one hand

Valuable creativity is restricted by lack of knowledge & foresight, communication problems and the resulting limitations. A product passes through more steps during its developing. Normally the processing is the bottleneck of the creativity, and it does not let your idea to be incorporated in the product. In the same way, the developer has not possibilities, to be creative in doing the compound formulation. Besides, unwanted aggravating influences are added between the various processes, such as e.g. characteristics’ changes of the material during machining, since processing conditions are often not specified or followed. The interactive influence and the information flow between the various processes can & must be efficiently used for the product conception.

From the idea to the end-product, we offer our customers the possibility to lean back and relax whereas we establish & realise all the process step of their successful product, reacting flexibly and creatively where needed.


Of course if wished the customer can always decide to enter into the process chain in a later point than the beginning or to jump out of it before the end. Have a look to the process steps below

Polymer testing, compound development and damage analysis

R&D build the foundation of our success. We do it since 1972 in our own laboratory in Kerpen, Germany. Through intensive research and continuous development of materials, our high performance plastics ZEDEX® have exceptional properties.

If the material for a specific application is not be present in our product range, we can modify an existing material making it suitable for the application or even develop it specifically. Our key competences are modifications to optimise tribological properties.

In failure cases of your components, we can mostly determine the cause of the malfunctions through mechanical tests, thermal tests, micro or macroscopic examinations of the defective parts. Optionally, we recommend you our appropriate high performance polymer ZEDEX® for your application.



Since 1968 we resolve problems, which come into being using plastic for machine elements.

A component made of plastic should be designed respecting the requirements, without having unnecessary safety properties. Every type of over-dimensioning has got negative effects, both economically and technologically. Only through experience, know-how and creativity, this target can be achieved.

We provide our support dimensioning your technical components and designing them suitable for material, processing condition and applied loads. We inform you about the optimal shape and thus, how to obtain the maximum efficiency.



Semi-finished, granules, 3D tribofilament, coating

We offer you the high performance plastics ZEDEX® in almost any shape:

  • As semi-finished with a finely coordinated range of dimensions
  • As cut-offs
  • As granules for further processing e.g. in the injection moulding
  • As 3D tribofilament for additive 3D printing
  • As coating to optimise the tribological properties of the pairing.

Additionally we offer tailor-made products as compound, blends and semi-finished based on construction and high-performance polymers such as PAI, PEEK, PEI, PESU, PET, PK, POM, PVDF, PPS, PU, TPI, PPSU, LCP, ETFE, PVDF etc.




Extrusion, injection moulding, machining, 3D printing, casting

We manufacture your component according to your drawing or you name your application and we design your component according to your requirements. No matter if extruded & machined, injection moulded or 3D printed, we determine the optimal manufacturing process for each component.

For the pump & naval sector we produce our new Blue Water & Dirty Water products by casting. These are available as cast semi-finished product or as bushing according to the customer’s drawing or based on our design.




Final parts such as precise plain bearing, slotted bearing, stave bearing, half shell bearing, foil bearing, hydrodynamic bearing, slideway, spindle nuts, track roller, gear, seal, scraper, wear part and insulating part, metal-plastic part, 3D printed part etc.

Since 1968 we have begun to successfully introduce plastic materials’ components from us designed, manufactured and made of engineering & high-performance ZEDEX® polymers, in fields of application considered visionary. We have learned a lot in our path, but our most precious spring of our Know-How is formed by the results of material tests and subsequently by those of the components, that we have been conducting since 1972.

Our core competences are modifications to optimise the tribological properties (no maintenance, transfer layer – dry running – wear resistance – low friction), nevertheless on construction & high-performance polymers we carry out all the usual and unusual modifications as well, e.g. fibre reinforcing, detectability, thermal and electrical conductivity, colouring, antistatic properties, mechanical resilience, thermal stability etc.

Through our experience we understand how technical components work and which reactions and processes inside the plastic materials take place during the use and which modifications are necessary to reduce negative reactions.



Our Vision

We want everyone to know, that we have the most appropriate product solutions.
