ZX-750V5T - is a thermoplastic material with antifriction characteristics based on polyimide (PI).

The form of technical specifications for bushings and guides   The form of technical specifications for sliding nuts   The form of technical specifications for gears
 
The latest development in the field of materials for high speeds and high temperatures. Particularly suitable for sliding speeds beyond 200 m/min and temperatures exceeding 300 °С.
Plain bearings slideways made of polymers ZX-750 should be applied if the use temperature exceeds +100°С, and the durability and dimensional stability need some improvement.
To apply

 

  • Stiff, hard, tough
  • High dimensional stability
  • High fatigue strength
  • Chemical resistance to solvents, dilute acids, alkalis, petroleum products
  • Good machinability, suitable for bonding and welding
  • Suitable for use in vacuum
  • Contains PTFE
  • Working temperature: -250°C to +300°C (+320°C);
  • Surface pressure (p): max. 41 (125) MPa;
  • Sliding speed (v): max. 350 m/min;
  • Fatigue (S): tensile fatigue strength at 20 °C and 1E06 stress cycles, 1 Hz = 35 MPa;
  • UV-radiation: resistant (1000 hours Xenon DIN 53597). Gamma-radiation: Limit absorbed dose 8000 kGy;
  • Water: max. water absorption: 0.7 %, up to +120°C resistant;
  • Fire behavior: Oxygen index (LOI): 52 %, classification: V-0 (UL94). Fireproof.

The advantages of ZX-750V5T over PEEK (polyetheretherketone):

  • 10 times higher pv-value, the best results of the work without lubrication
  • 5 times higher notch impact strength
  • 20-80 times higher durability when operating up to +100°C
