Description
Track vehicles and construction machinery are constantly evolving, as they face extreme environments and come into contact with dust, water and mud splashes, and stone, as well as the effects of ultra violet rays and aggressive fluids. Such restrictions mean that strong floating seals must be used that are able to resist abrasion and corrosion.
Floating seals are characterised by two identical metal friction rings mounted one on top of the other and centred in their groove by two rubber components that exercise a uniform axial pressure between the seal and the housing. The first metal ring remains static in its housing while the other, in rotation, ensures the sealing by creating friction between the two components in contact. The mating surface material of the friction ring is lapped to a width of approximately 2.5 mm.
The metal friction rings are conically designed with a perpendicular angle, so that when the seal rings come in contact there is a wedge-shaped gap perpendicular to the axis, which encourages the flow of lubricant towards the seal surfaces. Additionally, the friction exercised over time causes the friction surfaces to continually move towards the
inside diameter of the seal, which provides resistance to significant wear and thus extends its longevity.
