In addition to preventing leaks, the outer hub oil seal also helps to keep dirt and water out of the wheel hub. If these contaminants were to enter the hub, they could mix with the lubricant and create a sludgy, abrasive mixture that can damage the bearings and other components. By creating a barrier between the outside environment and the lubricant inside the hub, the oil seal helps to ensure smooth and efficient wheel operation.

One significant difference between dust seals and oil seals is their ability to handle pressure. Dust seals are not designed to withstand high pressures and are primarily focused on preventing contaminants from entering the system Dust seals are not designed to withstand high pressures and are primarily focused on preventing contaminants from entering the system

dust seal vs oil seal. In contrast, oil seals are designed to handle higher pressures and prevent oil from leaking out of the system under these conditions.


This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.
