Anti vibration mounts
Shim
The Mecanocaucho® height adjusting shims are used for the levelling the marine engine. They are composed of an anti corrosive steel plate in order to resist to the marine environments.
Technical characteristics
These shims avoid using the traditional height adjusting studs. The traditional levelling systems are subjected to cyclic bending moments and are exposed to eventual ruptures.
As a result of it most of the marine certification companies do not recommend to use height adjusting studs. Reference is made to DET NORSKE VERITAS (DNV) rules for ships / high speed craft –issue January 2016, Pt.4 Ch3 Sec.1 F202. This requirement is referred to rigid mounting, but is considered applicable to this topic.
