Floating oil seal is a common name of floating seal, belonging to a kind of mechanical seal in dynamic seal. It has super sealing performance under the harsh working environment of many pulverized coal, sediment, water and gas. It is a compact mechanical seal, mainly used in low-speed and heavy-duty occasions. It has many advantages, such as wear resistance, automatic compensation after end face wear, reliable operation, simple structure and so on. It is widely used in coal mine machinery. For example, bulldozer traveling mechanism, scraper conveyor head (tail) sprocket assembly, roadheader loading mechanism and cantilever section, left and right cutting drum and reducer of continuous shearer, etc.

Floating oil seal is a special type of mechanical seal. It is a compact mechanical seal developed to adapt to the harsh working environment. It has the advantages of strong anti pollution ability, wear resistance, impact resistance, reliable operation, automatic compensation for end wear, simple structure and so on. It is widely used in engineering machinery products. It is used in various conveyors, sand processing equipment, coagulation equipment, etc Soil equipment is also widely used. In coal mine machinery, it is mainly used in chain wheel of scraper conveyor, reducer, transmission mechanism of shearer, rocker arm, drum, etc. This kind of sealing products are widely used and mature in construction machinery and equipment, but in other industries, due to the small consumption, lack of basic theoretical data and use experience, the failure phenomenon is more common in the use process, and it is difficult to achieve the expected effect.
