20x35x7 oil seal. By sealing out these harmful particles, the oil seal helps to maintain the cleanliness and integrity of the mechanical system, prolonging its service life and reducing the need for costly repairs and replacements.
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.
