DO Type Duo Cone Seals
The DO type is the most commonly used mechanical face seal type, featuring two identical metal rings and two elastomer O-rings. This compact mechanical seal is primarily utilized in low-speed, heavy-load situations. It offers high wear resistance, automatic compensation after end face wear, reliable operation, a simple structure, and minimal maintenance.
Duo cone seals are widely applied in various machinery operations, including coal mining and infrastructure machinery, bulldozers, scraper conveyor head (tail) sprocket assemblies, and tunnel boring machines.

Operating Principles and Longevity of Duo Cone Seals
When the shaft rotates, it also drives the sealing ring surrounding it to rotate. Meanwhile, the other sealing ring remains static. This rotational force creates axial pressure at the sealing interface, enhancing the sealing effect by pushing out contaminants and fluids. As one sealing ring rotates relatively to the other, the compression of the O-rings presses them against each other, generating a sealing force between the two sealing faces.
The sealing faces maintain good contact, preventing the entry of dirt, sewage, and other contaminants from the outside. As the sealing faces wear down evenly over time, the elastic energy stored in the O-rings is released, providing axial compensation that ensures the duo cone seal remains effective for as long as possible. Typically, the service life lasts up to 5000 hours.
