Seals in industrial equipment play a pivotal role in preventing fluid (liquid or gas) leakage and keeping external contaminants out. They ensure the reliability and efficiency of the equipment across various applications. Specifically, they are utilized in components that undergo relative motion, such as shafts and bearings. Oil seals, for instance, prevent lubricant leakage and contaminant entry, typically employed in rotating shafts. O-rings, on the other hand, are extensively utilized for static and low-speed dynamic sealing. Oil seals hold an irreplaceable significance in industrial equipment. They not only prevent lubricant leakage and contaminant entry but also significantly extend equipment life, improve operational efficiency, and enhance reliability. Proper selection and maintenance of oil seals are crucial for ensuring efficient and stable operation of industrial equipment.
