Damper bearings represent the latest type of journal bearings, designed and manufactured to further minimize vibrations in rotating systems.
In this type of bearing, oil acts as a spring cushion to absorb system vibrations, which reduces the peak amplitude of equipment oscillations and stabilizes the system at higher rotational speeds.
The damping coefficient of tilting-pad bearings is lower than that of fixed-profile bearings. Therefore, they do not provide sufficient damping to prevent system instability.
Based on research and studies conducted on the operational performance of these parts, Paanir Company has introduced the damper bearing as the latest addition to its product line.
Advantages of squeezed film damper bearings:
- Controls both synchronous and sub synchronous vibrations.
- Significantly reduces the first critical amplitude.
- Provides smooth operation when passing through critical speeds.
- Maintains the shaft centered within the bearing.
- Reduces force transmission from the bearing to the foundation.
- Protects the machine against sudden forces caused by unbalance.
