Oil seal is also known as rotary shaft seal. They are often called grease, fluid or dirt seals. Oil seal is an integral part in any rotating and moving part assembly. They close spaces between stationary and moving components in mechanical equipment. In most applications, the seal is either partially or temporarily immersed or is simply exposed to splashing lubricant, particularly in engines, transmissions, gearboxes or axles. They are vital components of almost every type of machine and vehicle in operation. An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts. This is mainly achieved by the sealing element.
Sealing ring is used, in case of adequate lubrication by the medium to be sealed, preferably where shafts pass through walls in mills and large gearboxes in heavy machinery manufacture. Particularly robust static part Lasting radial contact pressure Highly wear-resistant
