A rotary shaft seal, also known as a lip seal or radial seal, is a device that creates a barrier between two environments the area where the rotating shaft operates and the external atmosphere. In high-pressure applications, these seals are engineered to withstand significant operational pressures, often exceeding several thousand psi. They are utilized in applications such as hydraulic pumps, turbines, and engines, where preventing fluid loss is critical.

Oil seals are integral components in various mechanical systems, contributing to enhanced performance, reliability, and longevity of machinery. As technology advances, the design and materials used in oil seals continue to evolve, enabling them to meet the increasing demands of modern applications. Proper maintenance and timely replacement of oil seals are crucial for preventing potential failures and ensuring optimal performance. Therefore, understanding their importance and functionality is essential for anyone involved in machinery maintenance and operations. The proper application of oil seals can save businesses significant costs in repairs and replacements while promoting smoother and more efficient operation.

The designation 20x35x7 refers to the dimensions of the oil seal. The numbers represent the inner diameter (20 mm), outer diameter (35 mm), and the thickness (7 mm) of the seal. The design of an oil seal is critical, as it must fit precisely to ensure a proper seal and prevent the ingress of dirt, dust, or moisture. The choice of material used for these seals often includes rubber compounds that enhance flexibility and resilience. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone, each chosen based on the specific application and operating conditions.
