METAL BELLOW SEALS

Metal Bellow Seals SSI-16G

Features

  • Rotating bellows seal

  • Balanced

  • No dynamic O-Ring, no hang-up, no shaft sleeve damage

  • Uniform seal face loading

  • Independent of direction of rotation
  • Ideally suited for highly corrosive and abrasive media
  • Compact design

Advantages

  • Resistant to abrasive particles

  • Self-cleaning, non-clogging design

  • Long seal life due to vibration dampeners at bellows

  • Ideal seal for very low as well high temperatures
