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 form a pair. The sealing ring, which is a sliding component, is not in contact with the shaft as it is supported by the rubber component and, therefore, closely follows the radial and shaft thrust movements.
Since they were developed for sludge applications, the sealing rings are made of an extremely hard material, resistant to wear and corrosion. The rubber component presses the sliding surfaces of the seal ring and also serves as a seal. Therefore, it is made of a material that is highly resistant to low temperatures and heat with little compression established for a longer lifespan.
The main uses of floating seals include caterpillar rollers, displacement transmissions and crazy wheels of construction and agricultural machinery, and also for conveyors, mixers and various excavation machines. In other words, they are widely used in relatively low-speed applications exposed to foreign matter.
