Types of Rotary Shaft Seals

In the world of machinery and automotive engineering, oil seals play a crucial role in maintaining the efficiency and longevity of engines and mechanical components. Among the various sizes and specifications available in the market, the 35x72x10 oil seal is a popular choice for many applications. This article delves into the key features, applications, and importance of the 35x72x10 oil seal.

Rotary lip seals function on the principle of pressure differential. As the shaft rotates, the sealing lip exerts a force against the surface, creating a tight seal that prevents the escape of fluids. This is achieved through the elastic deformation of the lip material, which conforms to the shaft's surface. As a result, the seal maintains contact even as the shaft moves, effectively mitigating the risk of leakage.

The 20x35x7 oil seal is widely used across several sectors, including automotive, industrial machinery, and aerospace. In automotive applications, it is commonly found in various components, such as engines, transmissions, and differentials. For instance, it effectively seals crankshafts and camshafts, ensuring that lubricants do not leak and that contaminants cannot enter the engine.
