2. Contaminant Protection Grease seals act as a first line of defense against contaminants. Dust, water, and debris can enter the bearing assembly and potentially lead to corrosion, pitting, and other forms of wear. By keeping these contaminants out, grease seals help maintain the integrity of the bearings.

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.

In industrial machinery, skeleton oil seals are utilized in gearboxes, pumps, and compressors
. These seals protect the internal components from environmental contaminants and ensure that the lubricants remain intact, thus reducing wear and tear on machinery. The robustness of skeleton oil seals makes them ideal for high-performance applications where reliability is paramount.
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.
