Sealing principle:

  Because there is an oil film controlled by the edge of the oil seal between the oil seal and the shaft, this oil film has fluid lubrication

characteristics. Under the action of the surface tension of the liquid, the rigidity of the oil film just makes the contact end of the oil film and the air

form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft.


   The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak;

if the thickness is too small, dry friction may occur, causing wear of the oil seal and shaft; if there is no oil film between the sealing lip and the

shaft, it will easily cause heat and wear.
 

  Therefore, during installation, some oil must be applied to the sealing ring, while ensuring that the skeleton oil seal is perpendicular to the axis of

the shaft. If it is not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft and cause excessive sealing lip. Wear.

During operation, the lubricant in the housing slightly seeps out to achieve the ideal state of forming an oil film on the sealing surface.
