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.
On the other hand, metal and plastic oil seals are chosen for applications where high temperatures, pressure, or chemical resistance are important. These materials offer excellent durability and reliability in challenging environments, making them ideal for heavy-duty machinery and industrial equipment.
Once the old seals are out, the cylinder should be thoroughly cleaned to remove any debris or residual oil that could interfere with the new seals' performance. Inspecting the cylinder for damage, such as scoring or scratches, is also critical at this stage.
