Hebei Hankai dust lip seal

wheel bearing hub seal.
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.

For instance, aggressive driving, such as hard stops and fast accelerations, can generate significant heat in the brake drums. Similarly, driving downhill or towing heavy loads can increase the thermal load on the brakes, pushing temperatures higher. In these situations, it is vital for drivers to be aware of their braking performance and heat generation.
