Features

  • Cartridge seal
  • Standardized dimensions
  • Short axial installation length (8.4 mm)
  • Dry running
  • Seal ring bears radial shaft movements
  • Compensates axial shaft movements
  • No sealing components mounted on the shaft and hence no additional shaft vibrations
  • Seal rings running contact-free - sliding faces and machine consume no additional power
  • One-piece seal ring (initial delivery)

Advantages

  • Easy installation
  • High reliability
