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.

In order to solve the problem of oil leakage in the transmission device of the coal mine face conveyor, floating oil seals are used in the design of low-quality transmission structures such as high-power reducers and sprockets, which completely solves the problem of oil leakage and short service life of the transmission device for a long time big problem.

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