25x38x7 oil seal.
The primary function of axle hub seals is to retain lubrication. Proper lubrication is essential for the smooth operation of moving parts, reducing friction and wear. Without effective sealing, the lubricant can leak out, leading to inadequate lubrication of the gears and bearings, which may cause premature wear and eventual failure of the components.
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.
