PTFE Rotary Shaft Seals - PTFE Lip Seals - Best Choice

PTFE Rotary Shaft Seals (PTFE lip seals) are often used in applications where traditional elastomer solutions would be unable to deliver the required level of performance. 

Equipment which is required to operate with high pressures, high speeds or that requires a dry running rotary seal, can often only be accommodated by using  products where the seal lips are manufactured from the latest filled PTFE polymer technology.  

Several standard ranges of PTFE lip seals are  available to cover a broad range of applications.  In the case of very demanding or extreme applications, a custom designed solution may present the best opportunity to deliver the required level of performance. 

Properties PTFE Rotary Shaft Seals - PTFE Lip Seals

  • Excellent chemical resistance
  • Suitable for applications with high thermal loads
    from –60°C to +200°C
  • Suitable in case of insufficient lubrication and dry runs
  • Also suitable for unhardened shafts
  • Highly wear-resistant sealing lip compound
  • Friction-optimized designs for minimum power loss
  • Suitable for high circumferential speeds
  • Low breakaway forces after prolonged downtimes (no stick-slip)
  • Antiadhesive behavior of the sealing lip
  • Special types available for the food processing and pharmaceutical industries

PTFE Rotary Shaft Seals (PTFE Lip Seals) - Application Examples:

  • Mineral and synthetic lubricants
  • Pharmaceutical products and foodstuffs (FDA recommendations for certain PTFE compounds)
  • Chemical waste water and wash water
  • Corrosive, fluid, and gaseous media
  • Powders and granulates
  • Coolant and lubricant fluids
  • Water and steam
  • Resins, glues, and pastes
  • Air/oxygen (BAM tests for certain PTFE compounds)
  • Heat transfer oils
