<span> skeleton oil seal is a dynamic sealing element, </span><span> The existence of "critical oil film" is a sufficient and necessary condition for oil seal sealing, and a leak-free seal is not allowed and impossible. Because the existence of the lubricating oil film is essential to ensure that the edge of the oil seal lubricates the friction lock, the existence of the lubricating oil film makes a certain amount of leakage inevitable. For rotary oil seals, in the process of use, if a small amount of leakage occurs within 50 to 100 hours of the initial operation is allowed. With the extension of operation time, the leakage will gradually stop, often such oil seal life is longer. Within the effective service life, a small amount of leakage is allowed, otherwise, it must be handled in accordance with the following common failure causes and troubleshooting methods of the oil seal. </span>
