Sandwich Mount - Trelleborg IAVS

Sandwich Mount

Sandwich Mount Product Range

This range of mountings is suited to the suspension of heavy equipment and machinery and is extensively used as a flexible mounting for large medium speed diesel marine propulsion units. The ratio of compression to shear stiffness rates can be varied by incorporating rigid interleave plates in the rubber section, thereby enabling the overall suspension properties to be optimized to isolate the major disturbing vibrations.

The mountings are usually installed in a vee arrangement and when correctly positioned, afford a high level of vibration isolation whilst at the same time keep movements of the suspended equipment, under the action of external forces, to a minimum.

Applications

Technical Specification

N.B. In many cases, the horizontal shear stiffness rates will reduce under compressive forces
