Difference Between One Single Lip Skeleton Oil Seal And One Double Lip Skeleton Oil Seal
The single lip skeleton oil seal has only a single sealing lip, and the double lip skeleton oil seal has two lips for sealing and dustproofing.
2. Use environment
Single lip skeleton oil seals are primarily used in environments with little or no dust and impurities, such as indoors or in tanks.
The double lip oil seal can be used in working environments with dust and impurities. The dust lip prevents dust and impurities from entering the cavity, so as not to damage the sealing lip and make the sealing lip lose its sealing effect.
