Floating seal from wonepart are commonly used in bulldozer and wheel loader construction machines Floating oil seal is a common name of floating seal, which is a kind of mechanical seal in dynamic seal. It has super sealing performance under harsh working environments such as coal powder, sand, water vapor, etc. It is a compact machine Sealed, mainly used in low speed and heavy load occasions. It has the advantages of automatic compensation after wear, end wear, reliable work, simple structure, etc. It 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. Introduction The planetary reducer with a floating oil seal on the walking part of the construction machinery performs dynamic sealing on the end face of the component. Due to its high reliability, it is also used as a dynamic seal for the output shaft of the bucket wheel of the dredger. This type of seal is a mechanical seal, which is generally composed of a floating ring of iron alloy material and a supporting O-ring seal of nitrile rubber. Floating rings are used in pairs, one rotates with the rotating parts and one is relatively stationary, which is very different from the oil seal ring.
