Hebei Hankai 70 90 10 oil seal

high temperature shaft seals.
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.

2. Production Method The manufacturing method can significantly impact FRP pipe pricing. Techniques such as filament winding, hand lay-up, and centrifugal casting are employed to produce FRP pipes. Filament winding, while more expensive due to its complexity and labor intensity, results in stronger and more uniform products, often justified by higher costs.
