Heat and attrition are generated by the parts moving against each other. The sealing function can only be ensured if an intentional defined leakage of oil is able to exit for seal lubrication, preventing seal wear and possible failure, while a tight static seal between shaft and sealing lip must be assured when the shaft is stationary.
Oil seals close spaces between fixed and moving parts and protect all kinds of ball and roller bearings. They keep rotating shafts and bearings from pollution and corrosive materials, and also prevent lubricants, oils, and liquids from leakage. An oil seal can have a single lip, double lip and even triple lip, so single lip seal is one lip to seal around the shaft, double lip seal is two lips sealing around this, and triple lip seals have three lips to seal.
Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.
There are a wide range of oil seals to select from for any number of uses, so this guide will break down the most common seals to help you choose the right one for whatever piece of machinery you are working on.
Successful assembly first requires careful preparation. By following a few simple steps, you significantly increase the chances of a flawless assembly.
Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.
