    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.
