Sealing element

What are the main factors that cause oil seal leakage? The main cause of oil leakage is that the oil seal is not tight. When the shaft is worn to form a groove, even if the new oil seal can not be sealed, it is because the contact pressure between the oil seal lip and the shaft drops, resulting in a small interference between the diameter of the oil seal lip and the shaft diameter after installation.

Now, taking the crankshaft oil seal of S195 diesel engine as an example, the main reasons for its loose sealing are analyzed as follows:

① Poor quality of oil seal manufacturing;

② Poor quality of shaft or bearing;

③ Improper use and maintenance;

④ Improper installation;

⑤ Improper storage and adverse effects caused by environmental pollution.
