Floating oil seal is a common name for floating seal, which is a kind of mechanical seal in dynamic seal. It has super sealing performance in harsh working environment such as coal powder, silt, moisture, etc. It is a compact mechanical Sealed, mainly used for low-speed and heavy-duty occasions. It has the advantages of wear resistance, automatic compensation after end face wear, reliable work, simple structure, etc., and is widely used in coal mine machinery. Such as bulldozer walking mechanism, scraper conveyor head (tail) sprocket assembly, roadheader loading mechanism and cantilever section, continuous shearer left and right cutting drum and reducer, etc.

Floating oil seal is a special type of mechanical seal. It is a compact mechanical seal method developed to adapt to the harsh working environment. It has strong anti-pollution ability, wear resistance, impact resistance, reliable work, and automatic end face wear. The advantages of compensation and simple structure are the most common applications in construction machinery products, and are also widely used in various conveyors, sand processing equipment, and concrete equipment. In coal mining machinery, it is mainly used for the sprocket of the scraper conveyor, the speed reducer and the transmission mechanism, rocker arm, drum, etc. of the coal shearer. This kind of sealing products are more common and mature in construction machinery and equipment, but in other industries, due to the small amount of use, the lack of basic theoretical data and use experience, the failure phenomenon is more common during use, and it is difficult to achieve the expected results.
