Oil seals – often called grease, fluid or dirt seals – close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. They also stop harmful contaminants from entering machinery, particularly in severe environments. Vital components of practically every type of machine and vehicle in operation, oil seals protect all types of precision-constructed, close-fitting ball, sleeve and roller bearings
Oil seals are used to prevent lubricants or other fluids from leaking outside of theequipment or machine. The main lip shape and the contact with the rotating shaft surface produce a pumping effect that returns the fluid, thus ensuring the fluid is contained inside.
