Feature of floating seal
Floating seals are simple products, consisting of two components: a seal ring made of special cast iron and a rubber component (O-ring/gasket). In use, two identical seals make a pair. The seal ring, which is a sliding component, is not in contact with the shaft since it is sustained by the rubber component, and therefore follows the radial and thrusting motions of the shaft closely.
Since they were developed for slurry applications, seal rings are made of an extremely hard, wear-resistant and corrosion-resistant material. The rubber component presses the seal ring's sliding surfaces and also serves as a seal. Therefore, it is made of a material that is highly resistant to cold temperatures and heat with little compression set for a longer useful life.
Main uses of floating seals include crawler rollers, travel drives and idlers of construction and agricultural machinery, and also for conveyors, mixers and various digging machines. In other words, they are used widely in relatively low-speed applications exposed to foreign matter.
