Brief: Discover the 180℃ PTFE Ball Bearings, designed for extreme corrosion resistance in harsh chemical environments. Ideal for strong acids, alkalis, and high-temperature applications up to 260℃. Learn about their unique properties and limitations in this detailed overview.
Related Product Features:
  • PTFE bearings offer the best anti-corrosion performance among all known engineering plastics.
  • Suitable for use in strong acids and alkalis, including HF, H2SO4, HNO3, and HCL (98% above).
  • Can withstand high temperatures with a short-time highest application temperature of 260℃.
  • Χαμηλός συντελεστής τριβής ολίσθησης 0,09-0,10 για ομαλή λειτουργία.
  • Rings and cage made with PTFE or PVDF; balls made with glass, ceramic, or stainless steel.
  • Not recommended for heavy load or high-speed applications due to low mechanical strength.
  • Density of 2.18 g/cm3 ensures lightweight yet durable performance.
  • Large dimension changes with temperature fluctuations, requiring careful application consideration.
Faqs:
  • What makes PTFE bearings suitable for corrosive environments?
    PTFE has the best anti-corrosion performance among all engineering plastics, making it ideal for strong acids and alkalis, including HF and concentrated H2SO4, HNO3, or HCL.
  • What is the maximum temperature PTFE bearings can handle?
    PTFE bearings can withstand short-time temperatures up to 260℃, though they are generally recommended for use at 180℃ for long-term applications.
  • Are PTFE bearings suitable for high-speed or heavy-load applications?
    No, PTFE bearings have low mechanical strength and are prone to deformation, making them unsuitable for heavy-load or high-speed applications.
