VD/VA Oil Water Seal FKM/NBR Rotary Water Seal

VA/VD water seal is a kind of made of pure rubber axial lip seal, it is often used for metallurgical machinery rolling roller axial end face seal of the head, water seal on the ontology of shaft neck hold tension makes its fixed on the axis of rotation axis neck, at the same time use its lips curved around the performance and the sealing of the pressing force of seal, To prevent water and impurities in the process of roll running into the roll rotation lubrication sealing body, to protect the requirements of the work roll axis lubrication sealing device. Water seal use of it in the rotation process of exists in the external cooling water flow of the centrifugal force, impurity and dust from the cooling water block in a sealed cavity, at the same time to prevent oil leakage inside the sealed cavity.
