HUNGER DS-I ROTARY SEAL

    DS-I ROTARY SEAL

    The space-saving rotary seal DS-I is designed specifically for sealing fast rotating components.

    From profile width 3.9 mm it has axial lubricant grooves in the slide ring surface which guarantee sufficient lubrication at higher speed.

    The gap between rotor and stator must be smaller than that of the RDI due to seal design.

    The DS-I is preferred to the DS-A due to its greater static contact surface.

    Depending on the specifications and operating condition it is recommended to have the running surface
    hardened to approx. 56 HRC or hard chromium plated.
