  • 6. Proper installation is key to effective oil seal performance.

  • To install an oil seal properly, the shaft must be undamaged. This is so the oil seal can do its job properly on the one hand, and to prevent it from being damaged during fitting on the other. In addition, it is very important to lubricate the shaft, the sealing lip and the bore with plenty of grease. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. The oil seal may also come into contact with the keyway, thread or other grooves when sliding over the shaft. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.

  • Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.

  • Features and Benefits of the 35x47x7 Oil Seal
  • Oil seals are fundamental components in the operation of machinery, providing a vital barrier between the internal lubricated areas and the external environment. These seals are specifically designed to prevent the leakage of oil or other fluids from the sealed chamber, while also preventing contaminants from entering. The rubber material used in their construction plays a crucial role in determining the performance, durability, and longevity of these seals.

  • No single physical property of rubbers is responsible for the successful performance of an oil seal or ‘O’ ring. The ultimate tensile strength, breaking elongation, modulus, shore hardness, creep and stress relaxation in tension and compression loads are all important physical properties that characterize a seal or ‘O’ ring. Compression strength and set together with stress relaxation or decay are important for effective sealing. The difference in these properties in a swollen seal is highly critical. An optimum swelling value in a fluid medium is a desirable feature. De-swelling decreases the seal pressure against the wall of the housing where the seal is fixed, leading to leakage. Over swelling minimizes the physical properties of the rubber. Seals made of polysulfide rubbers have extreme fuel resistance but undesirably high compression set. The effect of temperature on the seal is an important factor. Swelling under stress can increase at higher temperatures and a suitable compounding technique should be adopted to reduce this effect.

  • Despite its simplicity, the role of oil seal rubber is critical in industries ranging from automotive to aerospace, from manufacturing to food processing. Its effectiveness lies in its ability to adapt, protect, and endure in a multitude of environments and conditions. As technology advances, so does the development of more specialized and advanced rubber compounds, further solidifying the position of oil seal rubber as an indispensable element in modern industry.
