Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.
High pressure rotary shaft seals find extensive applications in several industries. In the automotive sector, they are utilized in engines, transmissions, and differentials, where they help prevent the escape of lubricants. In hydraulic applications, these seals ensure the efficient operation of hydraulic cylinders and pumps, crucial for heavy machinery and equipment.
When choosing oil seals, it is essential to consider several key factors that define their quality. First, the material selection is crucial; it should match the specific application requirements, such as temperature resistance, chemical compatibility, and flexibility. Second, the design of the oil seal, which often includes features like lips and grooves, determines its effectiveness in keeping lubricant in and contaminants out. Quality oil seals also exhibit a low rate of wear and excellent reliability over their operational life.
