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
