In addition to keeping oil inside the hub, the rear hub oil seal also prevents debris from entering the hub. Dirt, dust, and other contaminants can cause damage to the hub bearings and other components if they are allowed inside. The oil seal creates a tight seal around the hub, keeping these harmful particles out and preserving the integrity of the hub assembly.

Another important function of a dust seal is to prevent leakage of hydraulic fluid. If dust and dirt particles are allowed to enter the cylinder, they can create small gaps and openings that allow fluid to escape

hydraulic cylinder dust seal. This can result in a loss of pressure and reduced performance of the hydraulic system. Dust seals help maintain the integrity of the cylinder by sealing off any potential entry points for contaminants, preventing leaks and ensuring the proper functioning of the system.

Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.
