　　Floating seal, also known as a mechanical face seal or heavy duty seal, is specifically engineered for rotating applications in extremely harsh environments where they withstand severe wear and prevent the ingress of harsh and abrasive external media. It is a high-performance seal that integrates floating ring seal, gap seal, and comb tooth seal, and uses the tension of the oil film to effectively prevent leakage.

　　There are two different types of Mechanical Face Seals: Type DO, which uses an O-Ring as a secondary sealing element, and Type DF, which has an elastomer with a diamond-shaped cross-section as a secondary sealing element instead of the O-Ring. Both types consist of two identical metal seal rings mounted in two separate housings face-to-face on a lapped seal face. The metal rings are centered within their housings by an elastomer element. One half of the Mechanical Face Seal remains static in the housing, while the other half rotates with its counter face.

　　Mechanical Face Seals are predominantly used for sealing the bearings in construction machinery or production plants operating under extremely arduous conditions and subject to severe wear. These include tracked vehicles such as excavators and bulldozers, conveyor systems, heavy trucks, axles, tunnel boring machines, agriculture machines, and mining machines. They are also proven for use in gearboxes, mixers, stirrers, wind-driven power stations, and other applications with similar conditions or where minimized maintenance levels are needed.
