Precision plastic bearings

  *POM Engineering plastics elucidation
      POM Polyoxymethylene can be used in tem-peratures ranging from -60≧to +100≧. The high surface strength is only surpassed by a few materials. POM shows good sliding roperties and high resistance to wear and tear because of the high strength and smooth surface. There is a very low risk of stress cracks. POM (Copolymere) exhibits a high thermal stability and a high resistance to chemicals (high resistance to hydrolysis).

  *PEEK Engineering plastics elucidation
PEEK Polyether etherketone can be used at very high temperatures (+260≧) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength, PEEK exhibits excellent chemical resistance, very good dielectric properties up to +260≧ and a very good resistance to all kinds of radiation. Lmportantl it is self-extinguishing according to UL 94.
