VIBRATION DAMPING V017
In an O-ring mechanical seal the dynamic elastomer provides a damping effect. Metal bellows seals do not have a dynamic elastomer so they have to be provided with some other method of providing damping
The most common solution is to let the rotating seal face holder bounce off the shaft or sleeve.
- Damping is important in metal bellows seal designs. The elastomer acts as a vibration damper in O-ring type seals.
- The vibration can chip carbon faces, destroy anti-rotation drive lugs, and open the lapped seal faces.
