Do you know what the sealing principle of Buy skeleton oil seal products is? Let's have a simple understanding together!
Due to the presence of an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has fluid lubricating properties. Under the action of the surface tension of the liquid, the rigidity of the oil film just makes the oil film and the air contact end form a meniscus, which prevents the leakage of the working medium and thus 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 the oil seal and shaft to wear; if there is no oil film between the sealing lip and the shaft, it is easy to cause heat and wear. 

Therefore, when installing, it is necessary to apply some oil on the sealing ring, and at the same time ensure that the Buy skeleton oil seal products are perpendicular to the shaft line. Excessive wear of the lip. During operation, the lubricant in the casing seeps out a little, so that it is ideal to form an oil film on the sealing surface.
The above is a brief introduction to the relevant knowledge of the sealing principle of Buy skeleton oil seal products.
