Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.
Demand dynamics also play a significant role in the pricing of oil seals. As global industries recover from economic downturns, the demand for machinery and vehicles tends to rise. This increased demand for oil seals can lead to higher prices if supply cannot keep pace. For example, during the economic recovery following the COVID-19 pandemic, many industries saw a surge in demand for automotive parts, including oil seals, straining the supply chains and driving prices upward. Moreover, the increasing trend toward electric vehicles, while potentially reducing some demand for traditional oil seals, has sparked interest in specialized seals for new technologies, which can also influence market prices.
