Hydraulic motor oil seals are typically made from high-quality materials that can withstand harsh operating conditions. Common materials include rubber (such as nitrile or fluorocarbon), polyurethane, and composite materials. The choice of material depends on factors such as temperature, pressure, and the type of hydraulic fluid used.
In addition to preventing oil leakage, oil seals also help to maintain proper lubrication levels within a system. By containing the oil within a specific area, the seal ensures that the moving parts are properly lubricated, reducing friction and wear. This ultimately leads to a longer lifespan for the components and overall improved performance of the system.
