Mechanical face seal is widely used in the slow speed operation and the place required high lubrication reliablity and long working lifetime, such as mining machinery, agricultural machinery, construction machinery, heavy truck, coal cutter, tunneling machine, scraper conveyor and cultivated land machine, etc.

Due to the harsh mining environment, impact load, high vibration, and continuous intrusion of mineral dust and dust, it is easy to cause oil seals on mechanical equipment to fail and cause serious oil leakage. Therefore, mining equipment mostly uses floating oil seals. The advantage of mechanical face seals is resistance. Abrasion, impact resistance, a certain degree of self-adaptability, simple structure, long life, especially good anti-pollution performance. These advantages determine that the mechanical face seal is particularly suitable for mining machinery. It is precisely based on this consideration that mining trucks often use mechanical face seals.

Applied in all kinds of construction machinery, agricultural machinery, building machinery and mining machinery.
