Features

  • For unstepped shafts
  • Single seal
  • Balanced
  • Independent of direction of rotation
  • Encapsulated rotating spring

Advantages

  • Especially designed for solids containing and highly viscous media
  • Springs are protected from the product
  • Rugged and reliable design
  • No damage of the shaft by dynamically loaded O-Ring
  • Universal application
  • Variants for sterile operation available
  • Increased axial movement
  • DiamondFace coating possible
  • Spring protection and vibration damping
  • Insensitive to temperature changes
  • 100 % compatible to HJ9... for l1k

Operating range

Shaft diameter:
d1 = 18 ... 100 mm (0.71" ... 4")
Pressure:
p1*) = vacuum ... 40 bar (vacuum ... 580 PSI)
Temperature:
t = -50 °C ... +220 °C (-58 °F ... +430 °F)
Sliding velocity: vg = 20 m/s (66 ft/s)
Axial movement:
d1 = 18 ... 25 mm: ±0,5 mm
d1 = 28 ... 55 mm: ±0,8 mm
d1 = 60 ... 100 mm: ±1,0 mm

* An integral stationary seat lock is not needed within the permissible low pressure range. For prolonged operation under vacuum it is necessary to arrange for quenching on the atmospheric side.
