Hebei Hankai high pressure lip seal

In addition to preventing fluid loss, oil seals also protect machinery from external contaminants such as dust, dirt, and moisture. These particles can cause significant damage if they enter the inner workings of equipment. The presence of a well-functioning oil seal eliminates this risk, fostering a clean operational environment.

Finally, the 7% relates to the material composition and the durability of the seals. Oil seals are typically constructed from various compounds, including elastomers and polyurethane, each tailored for specific environmental conditions. A 7% threshold can indicate the percentage of material degradation that is acceptable over a defined lifespan. High-quality seals are engineered to endure extreme pressures and environmental challenges, maintaining their integrity even as their material composition undergoes wear.

Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.

Oil seals, often referred to as rotary seals or oil slingers, are devices used to seal rotating shafts or components in equipment that contain fluids, such as oils or greases. These seals are typically made from rubber, polyurethane, or other synthetic materials, which provide excellent resilience and wear resistance. The primary function of oil seals is to contain the lubricant within the system while simultaneously keeping contaminants out, thus maintaining optimal performance.
