Front hub seals are designed to create a barrier between the external environment and the internal components of the hub assembly. They help to keep lubricants inside while preventing external contaminants from infiltrating the bearings. This is vital because wheel bearings rely on grease or oil for lubrication, and any ingress of dirt or water can lead to premature wear, overheating, and ultimately, bearing failure.

One of the primary factors affecting the price of oil seals is the cost of raw materials. Oil seals are typically made from rubber, polyurethane, or various composites that provide flexibility, durability, and resistance to wear and temperature fluctuations. The prices of these materials can fluctuate based on global supply and demand, energy costs, and geopolitical events. For instance, an increase in the price of crude oil—often a precursor to escalating rubber prices—can lead to higher costs for oil seal manufacturers. Conversely, a decrease in raw material prices could result in lower prices for consumers.
