| Metalastik® type D series |
Metalastik® D Series Mountings are suitable for the suspension of heavy equipment or machinery where insulation against low frequency vibration is required with the additional benefit of excellent high frequency acoustic attenuation. |
|
|
| Features/Applications |
The relatively large rubber volume ensures high degrees of insulation against low frequency disturbing vibrations. Differing stiffness rates in the two horizontal modes enables suspension characteristics to be optimised by appropriate
orientation of the mountings. |
The mountings can be used in conjunction with additional bonded rubber buffers to limit movement of the suspended equipment under shock loading. |
Parts can be supplied to meet naval specification requirements and also with plain flanges for drilling by the customer. |
| Applications include : |
| • Medium speed marine propulsion engines |
| • Generator sets |
| • Gearboxes |
| • Pumps |
| • Compressors and refrigeration systems |
