Many devices, conventionally, utilize a housing filled with fluid or lubricant and shafts passing through the wall of the housing to drive or be driven by an external component. Internal to the housing is a gear set or other mechanical device that modifies the rotational energy, torque or speed supplied from one shaft to another shaft. Such devices must be fluidly sealed from the external environment to ensure that contaminants do not enter the housing nor does fluid leak from the housing to the external environment. However, with the use of rotating shafts in such an arrangement, it is difficult to seal the housing as the rotation of a shaft with respect to a fixed housing wall requires some space between. To aid in fluidly sealing this space, fluid seals are positioned between the shaft and wall. Typical fluid seals are donut-like with a through bore to press against the seal area of the shaft and have an outer surface that engages with an aperture formed in the housing. As a result, the shaft rotates and slides against the fluid seal and the fluid seal presses against the seal area of the shaft to form a barrier between the inside of the housing and the external environment. However, as rotation of the shaft against the seal is resisted by friction, energy is lost to heat due to this resistance. Moreover, the seal and shaft can be worn and damaged due to this friction. As a result, seals and shafts must be replaced which increases labor and maintenance costs and creates downtime.

Oil seals
are mainly used for gear box, motors, automobile, engines, pumps, wheel, etc. The primary purpose of using oil seals is to prevent leakages from a rotating shaft. Oil seals are also useful when it comes to preventing oil leakages due to dust intrusion from external air. Not only do they prevent leakages of lubricants, but they are also helpful in preventing chemicals, water, and gas from gaps in the equipment.
