Replace bronze with ZEDEX-410 plastics?

ZEDEX-410 (based on polyetherimide) plastics are ideal if you want to reduce the cost and weight of components. Due to their unique sliding properties, ZEDEX-410 have a longer service life in sliding element applications. For most applications, ZX-410 is also suitable for dry running. A particular advantage of ZX-410 plastics, despite their hardness, is their elasticity. The material is able to compensate for geometric errors. In addition, the elastic surface of ZX-410 absorbs abrasive foreign particles from dusty environments, thus ensuring longer maintenance-free operation. At the same time, this also protects other components. Another advantage of ZX-410's elasticity is that it distributes point forces over its entire surface, reducing the chances of material fatigue due to one-sided loading. ZX-410 plastics have a damping effect compared to bronze, which makes them resistant to impacts and reduces the acoustic volume of individual components in operation.


ZEDEX-410 (based on polyetherimide) is a corrosion-resistant material and resistant to numerous external influences such as radiation or liquids:


  • Resistant to alcohols, fuel for motor vehicles and aircraft, lubricants, cleanser

  • Resistant to weak acids and alkalis (PH-value <9)

  • Resistant to salt solutions and ether

  • Resistant to hydrolysis of hot water and steam

  • Resistant to UV radiation
