1. Anti -corrosion dust invasion

The cylindrical shape outside the oil seal ensures the static seal of the inner cavity. The outer edge of the rubber on the internal metal skeleton and the exposed metal skeleton edges are applied to the skeleton seal. Most of them need to be polished and electroplating anticorrosive coating. Twist spring sealing lips ensure the movement of the shaft. Static sealing stability improves the sealing lip structure of the oil seal, achieves certain characteristics, and then improves the stability of the seal. Under special circumstances, add anti -fainting lips or add multiple anti -fade lips under special circumstances to avoid external pollutants and dust invasion.

2. heat resistance

Due to design and structural reasons, the high -rotation frequency of the shaft should be sealed with high -speed wear -resistant oil sealing. The low -speed shaft uses a slow oil sealing product. The low -speed oil seal cannot be carried out at a high -speed rotation shaft. On the contrary, The temperature of the working environment at high temperature should be selected for polypropylene or silicon. Fluorine. Fluorine silicon rubber. It should also work hard to reduce the oil temperature in the fuel tank. Cold -resistant rubber should be selected in low temperature applications. The pressure of stress general oil seal products is poor. When the pressure is too large, the oil seal will deform. In the case of excessive pressure, the skeleton sealing should use the pressure -resistant support ring or increase the pressure -resistant sealing products.

3. High environmental requirements

Skeleton seal is a component that requires higher storage environment. If it is not handled properly during transportation and storage, it will affect the skeleton seal itself, and even the normal use of the entire machine. Try not to open the package too frequently before use. High temperature and high fever can cause premature rubber aging, so the skeleton seal should be avoided in the sun or under high temperature for a long time. Do not collide during transportation to avoid distorted springs falling off or oil seal deformation. To prevent corrosion, stay away from the acid -base liquid, you cannot tie the skeleton seal with a thread to prevent the sealing lip damage.
