DIN 3869 Profile Sealing Ring by Material, Finish and Size

An oil seal, also known as a shaft sealing ring, rotary shaft seal, or simply a shaft seal, is a mechanical device designed to prevent fluids—such as oil or grease—from leaking out along a rotating or moving shaft. At the same time, it also prevents external contaminants like dust, dirt, and moisture from entering the machineryOil seals are installed where a shaft passes through a housing (like in pumps, gearboxes, or engines). The flexible lip of the seal is pressed against the shaft—often aided by the garter spring—to form a tight barrier. This prevents lubricants from escaping and keeps contaminants from entering the machinery.
