1. Common materials for oil seals are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc.

2.Oil seals are required in all parts of the body that contain liquid lubricating oil and connected to the outside. Some are rubber and some are metal, most of them are steel reinforced rubber.

3.Tight seal of oil seal is the main factor causing oil leakage. When the shaft is worn and grooved, even if the new seal can not be sealed, it is because the contact pressure between the seal lip and shaft decreases, resulting in too small interference between the seal lip diameter and shaft diameter after installation.
