VA VS VL VEType rotary shafts rubber seal Rotating sealring

Short Description:

Water seal is a kind of axial lip seal made of pure rubber, it is commonly used for metallurgical machinery roller shaft head axial face seal, water seal relies on its body to the journal tension to fix it on the journal of the rotation shaft, while using its lip curvature performance and its urgency on the seal force of the sealing pair, thereby preventing water and impurities from entering the roll rotation lubrication sealing body during the roll, in order to achieve the normal operation requirements of the rotary shaft lubrication sealing device to protect the roll rotational shaft lubrication sealing device. The hydroseal uses the fluid centrifugal force of the cooling water present outside during the rotation process to keep impurities and dust in the cooling water out of the sealing chamber while preventing grease leakage inside the sealing chamber.

Product Features

1.  Pure rubber elastomer material without metal parts;
2. Alleviate the design work, no installation and processing requirements;
3. The requirements of shaft matching surface processing and surface accuracy and hardness are canceled, and the shaft surface does not have 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 less, and the service life is long;
6. It has both sealing and dustproof functions.

VA water seal installation

VA type water seal installation does not need to design installation chamfer. The V-shaped water seal is elastic and can be stretched and pushed onto other parts. The V-shaped ring can be stretched by up to 20%, so it is easy to install.

In many cases, V-shaped water seals can be installed with a simple tool that turns the shaft and pushes or centers the V-shaped water seal to the correct installation position with a bladeless tool.

If replacing the V-shaped water seal involves the time-consuming operation of removing several other parts, you can cut the V-shaped water seal into two parts, place them in the appropriate position, and then connect the two parts with adhesive materials and tools. Note that the connection cannot be stretched.
