3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.

One of the main benefits of using a hub dust seal is the protection it provides for the bearings inside the hub. Bearings are critical components of any machinery, and they are particularly vulnerable to damage from dust and other contaminants. By using a hub dust seal, you can help to extend the lifespan of your bearings and reduce the need for costly repairs or replacements.

The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.
