Va Type Water Seal-Va Water Seal Seal Ring for Shaft

     The VA water seal is an axial lip seal made of pure rubber. It is often used for the axial end face seal of the head of the roll shaft of metallurgical machinery. On the journal of the shaft, at the same time, the sealing pair formed by the bending performance of the lip and its pressing force on the seal is used to prevent water and impurities from entering the rotating and lubricating sealing body of the roll during the operation of the roll, so as to protect the rotating shaft of the roll. Requirements for proper functioning of lubricating seals. The water seal utilizes the fluid centrifugal force of the cooling water that exists outside during the rotation process to block the impurities and dust in the cooling water from the sealing cavity and prevent the leakage of grease inside the sealing cavity.

 Features

1. Pure rubber elastomer material without metal parts;

2. The design work is reduced, and there is no installation and processing requirements;

3. The requirements for shaft matching surface processing, surface accuracy and hardness are cancelled, and the shaft surface does not need to be hardened;

4. Simple and reliable installation and disassembly;

5. The surface contact pressure is small, so the friction force is small, the friction loss and friction heat are small, and the service life is long;

6. It has both sealing and dustproof functions.
