Carbon seal

for aircraftspring

In certain extreme applications, a part made of individual segments may meet your critical performance requirements better than a single-piece unit. Segmented seals ride directly along the shaft and are primarily used in low-pressure applications. These seals contain a series of segmented carbon rings which contact the shaft or rotor. Segments inside the seal housing are kept in the proper location by anti-rotation keys or pins. A secondary seal is formed by the axial spring loading of the seal rings against the internal surface of the housing face. During movement, a continuous seal is always in contact with either the primary or secondary sealing surfaces. PRODUCT APPLICATIONS Aerospace Industry Industrial Industry Ideal For: Gas seals and for sealing low-pressure liquids FEATURES & BENEFITS Benefits: Tolerance to unlimited shaft axial movement Prevents oil and contaminant migration into the process gas side Leakage rates remain constant over the life of the seal Features: Rides directly along the shaft Special gap segments permit the seal to adjust dimensionally for minimal leakage Compression and garter springs ensure that segments remain in contact with mating surfaces during low delta pressure and shutdown conditions Design Configurations: Various seal ring segment configurations Pressure-balanced segments Fractured rings Multiple seal labyrinth Internally pressurized seal Internally vented seal
