Wheel bearing grease seals, often referred to simply as grease seals, are fitted between the stationary and rotating parts of a wheel bearing assembly. They create a barrier that prevents grease from leaking out while simultaneously keeping dirt, dust, moisture, and other contaminants at bay. Typically made from durable materials such as rubber or synthetic compounds, these seals are engineered to withstand high temperatures and pressures, which can occur during operation.

4. Oil and Gas Industry In drilling operations and machinery that process petroleum products, high-pressure oil seals are critical to preventing leaks and ensuring the safe operation of equipment under intense pressures.

Moreover, these seals can take various forms, such as single lip, double lip, or even labyrinth seals, depending on the specific application requirements. Each design has its own advantages; for instance, double lip seals provide an added layer of protection against fluid leakage and contamination.

4. O-Rings Though often used in static applications, specifically designed O-rings can serve as effective shaft seals in hydraulic systems. Their circular shape allows them to compress and create a tight seal under pressure.
