3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.
what is the function of oil seal

In the automotive industry, for instance, dust wiper seals are crucial in maintaining the cleanliness of hydraulic cylinders, steering systems, and suspension components. They protect these systems from road debris, dust, and moisture, ensuring smooth operation and reducing maintenance needs They protect these systems from road debris, dust, and moisture, ensuring smooth operation and reducing maintenance needs

Oil seals come in various designs depending on the specific requirements of the machinery. The 20x30x7 oil seal, for example, is a standard radial shaft seal that is installed along the shaft to prevent oil from leaking out or contaminants from entering the machinery. This type of seal is commonly used in engines, gearboxes, and other rotating equipment where the sealing of fluids is essential.
