LY9TCS-F

Features

  • API 682 Category 2 and 3, Type C seal
  • Dual seal, face-to-face
  • Balanced
  • Cartridge unit
  • Stationary metal bellows
  • Shrink fitted seal rings and solid mating rings

Advantages

  • Suitable for higher speeds
  • Good followability du to no influence from run-out, squareness or vibration of the shaft
  • Compact design
  • Also available in double ply design
  • Suited for application with extreme high and low temperature
  • Absence of dynamic O-ring eliminates/reduces seal face hang-up
  • Bellows design minimizes variation in face load due to shaft expansion or face wear
  • Resistant to abrasive particles in the medium, no shaft or sleeve fretting
