Oil seals, also known as lip seals or rotary shaft seals, are critical components used to prevent the leakage of fluids, such as oils and lubricants, from rotary shafts or around stationary components. They serve a dual purpose keeping contaminants out and ensuring lubricants stay in, thereby ensuring the efficient functioning of machinery.

Rotary lip seals are employed in a wide array of industries, including automotive, aerospace, manufacturing, and agriculture. In automotive applications, they are commonly found in engines, transmissions, and wheel hubs, where they play a vital role in ensuring the longevity and efficiency of the vehicle. In hydraulic systems, these seals prevent fluid leakage, ensuring that equipment operates smoothly and effectively.

Wiper oil seals often feature a unique design that includes a lip that contacts the shaft or surface it is sealing against. This lip creates a dynamic seal that adapts to the movement of the shaft, maintaining a tight enclosure even as the equipment operates. The design often includes an additional wiper or dust lip, which helps remove contaminants that come into contact with the seal, further enhancing its protective capabilities.
