Leakage Rates

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.

The complexity of the manufacturing process also plays a significant role in determining the price of oil seals. Production involves several steps, including material preparation, molding, and quality control. High-precision seals that are engineered for specific applications typically come at a higher price point due to the advanced technology and expertise required in their production. Manufacturers with stringent quality control measures may also incur higher operational costs, which can be passed on to consumers through increased prices.
