In addition to their durability, metal oil seals also offer excellent sealing capabilities, helping to prevent the escape of oil and other fluids from equipment. This is crucial for maintaining the proper lubrication of moving parts and ensuring that machinery operates efficiently. By creating a tight seal between mating surfaces, metal oil seals help to reduce friction and wear, extending the lifespan of components and reducing the need for maintenance.

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.
