cassette oil 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 those whose pain stems from muscular issues rather than structural problems, this relaxation can be particularly beneficial. It allows for a greater range of motion and can facilitate easier movement throughout the day.
