oil for wheel hub
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.


Brake drums are typically made from cast iron due to its strength, durability, and thermal conductivity. They are designed to withstand the extreme conditions associated with heavy braking, such as high temperatures and significant wear and tear. Over time, however, brake drums can become warped or worn, leading to reduced braking efficiency.
