Hebei Hankai high temp oil seal

Rotary shaft seals, also known as oil seals or lip seals, are critical components in various mechanical systems. They are designed to prevent the leakage of lubricants, oils, and other fluids while also protecting the internal components from dust, dirt, and other contaminants. These seals play a vital role in ensuring the smooth operation and longevity of machinery and automotive systems.

1. Leak Prevention One of the primary functions of hydraulic shaft seals is to prevent leaks. Hydraulic fluids can be expensive and environmentally hazardous, making containment crucial. Effective sealing not only saves costs but also protects the environment and enhances safety.

The 20x35x7 oil seal refers to its dimensions in millimeters a diameter of 20 mm, an outer diameter of 35 mm, and a width of 7 mm. This specific sizing makes it ideal for various applications that require a compact sealing solution. The oil seal is generally made from rubber or elastomeric materials, which provide flexibility and resilience against physical wear and chemical exposure. Its design often includes a metal casing, which enhances its structural integrity while facilitating installation.

Rotary shaft seals are widely used across many industries, including automotive, aerospace, manufacturing, and consumer products. In the automotive sector, they can be found in engines, transmissions, and wheel hubs. Their primary role is to manage oil flow, thereby preventing leaks that could lead to system failures or costly repairs. Similarly, in industrial machines, these seals help maintain lubrication in bearing systems and pumps, ensuring a smooth operation.
