In addition to protecting the bearings from external contaminants, hub dust seals also help to retain the lubricant that is essential for proper functioning
. As dust and dirt particles infiltrate the hub, they can mix with the lubricant and form a gritty paste that can accelerate wear on the bearings. By keeping the hub sealed tight, the dust seal ensures that the lubricant stays clean and free from contamination, thus extending the life of the bearings.hub dust seal

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.
