Also known as mechanical face seals or heavy-duty seals, they are also called Duo Cone seals or metal seals. Floating seals are designed to solve rotary applications in extremely harsh environments, withstanding severe wear and preventing the ingress of harsh and abrasive external media. It is a high-performance seal that combines a floating ring seal, a gap seal, and a comb seal, utilizing the tension of the oil film to effectively prevent leakage.
