It is one of the oldest brands in the industry after its founder Mr. Sun incorporated the company in 1986 following their development of the oil seals. Today, KDIK provide quality products and services to customers around the globe. KDIK products are designed and built using high-grade materials and under precision tolerances, ensuring strong, consistent performance even in demanding operating environments. It is this dedication to excellence that has made the KDIK brand the preferred choice for fleet owners to OE parts manufacturers worldwide. The automotive oil seal, officially known as "rotating shaft lip-type sealing ring", is a seemingly insignificant yet crucial component in automobiles. Its core function is to provide a permanent "bidirectional isolation" between the lubricating oil (grease) and the external environment. Its basic working principle is to maintain a very thin and stable oil film between the flexible rubber lip and the rotating shaft surface. Under the action of surface tension, this layer of oil film can not only lubricate the lip to reduce wear, but also seal the oil to prevent leakage. Core Function Oil Sealing (Main Function): Prevents the leakage of lubricating fluids such as transmission oil, engine oil, gear oil, and lubricating grease from the gaps of mechanical components. Dust-proof (protection function): Prevent external dust, sand, moisture, chemical pollutants, etc. from entering the interior of precision components such as bearings and gears. Separation medium: Used in certain areas to separate two different media, for example, to prevent the mixture of transmission oil and clutch oil. Reason for failure Normal aging: If rubber is exposed to high temperatures and oil for a long time, it will harden, crack and lose its elasticity. Installation errors: account for over 80% of the early failures. Lip scratches, installation in the wrong position, and improper use of tools result in deformation. Surface damage of the shaft: The shaft is worn, rusted, and has scratches, which leads to poor sealing. Operating conditions are extremely harsh: extremely high temperature, extremely high speed, large pressure fluctuations, and exposure to strong solvents. Sealing lip wear: During installation, no lubrication was applied, and the sealing lip was instantly abraded during the first startup.
