HUNGER RSI ROTARY SEAL

    RSI ROTARY SEAL

    The HUNGER rotary seal type RSI consists of a highest wear-resistant PTFE-compound slide ring and three
    (double-acting) or two (single-acting) O-Rings made of Fluoro Rubber Monomer, which provide the pretension
    of the sealing lips.
    Additional axial fixing of the seal ensures that dynamic movement takes place at the internal diameter.
    Depending on the specifications and operating conditions it is recommended to have the running surface hardened to approx. 56 HRC or hard chromium plated.
