Technical Specifications

Description & Advantages

 

Testing has shown that PTFE based compounds are resistant to virtually all media, cutting fluids and slideway oils. Additionally, these compounds feature outstanding wear resistance and friction characteristics. Head-to-head material testing has shown that NS - 244 Turquoise Sheet outperforms key competitive materials for low friction. NS - 244 Turquoise Sheet was developed to meet the needs of machine tool manufacturers looking to improve machine tool efficiencies through low friction material technology, reduce stick-slip effect in machine transitions while still maintaining positioning accuracy and vibration damping.

 

  • Low friction without stick slip for positional accuracy at different velocities, especially low speeds
  • Low coefficient of friction in intermittent lack of lubrications
  • Chemical resistant to a broad range of lubricants for extended product life
  • Reduces machine tool vibration through damping characteristics
  • Minimal abrasion of hardware, preventing damage to counter surfaces
  • High wear resistance for extended product life
  • Thicknesses to meet design requirements
