Floating Oil Seal/mechanical Face Seal

Oil seal is the seal of lubricant oil. It is an important and indispensable original of lubrication sealing system of rotary shaft of general purpose machinery. Commonly used in a variety of mechanical bearing point, especially the position of rolling bearing. its function is isolation the oil cavity and outside.

Mechanical Face Seals or heavy duty seals are specifically engineered for rotating applications in extremely arduous environments where they withstand severe wear and prevent ingress of harsh and abrasive external media. A Mechanical Face Seal is also known as Heavy Duty Seal, Face Seal, Lifetime Seal, Floating Seal, Duo Cone Seal, Toric Seal.

Type DO is the most common form that uses an O-Ring as a secondary sealing element
Type DO 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.



Product Applications

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
Mining machines
Mechanical Face Seals are proven for use in gearboxes, mixers, stirrers, wind-driven power stations and other applications with similar conditions or where minimized maintenance levels are needed.
