3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.
what is the function of oil seal

The hub axle seal's primary function is to keep the axle lubricated. The lubricant, often a type of grease or oil, is crucial for reducing friction between moving parts. Without proper lubrication, the components can suffer from overheating and excessive wear, potentially leading to significant damage and costly repairs. Additionally, the seal prevents water and dirt from entering the axle assembly, which can cause rust and corrosion, further jeopardizing the integrity of the axle.
