wheel hub seal. This noise is caused by the lack of lubrication in the wheel hub, which can lead to metal-on-metal contact and damage.
In addition to reducing friction, hydraulic piston oil seals also help maintain the cleanliness of the hydraulic fluid. By sealing the piston chamber, these seals prevent dirt, debris, and other contaminants from entering the system and causing damage to the hydraulic components. This is particularly important in industries where hydraulic systems are exposed to harsh environments or heavy use.
