The R&D Engine Mounts are specifically designed for the rigors of
marine, industrial, commercial, and heavy equipment applications.
These engine mounts are pre-loaded to provide a dampening effect
when encountering upward or downward pressure. Most R&D mounts
are shear loaded to absorb forward and reverse thrust, yet soft enough
to isolate engine vibrations from the surface where they are mounted.
To assist in the ease of installation, the mounts have nuts to adjust the
height. The slotted holes in the base of the mount assist in alignment
and installation.
To help increase the longevity of the mounts, all steel parts are zinc
plated and passivated to limit corrosion. The threads of the stud are
rolled and reduce the possibility of shearing the stud. This technology
produces a significantly stronger thread than possible when the
material is cut away in conventional cut-thread die methods. More
specifically, the thread rolling (cold forming) process strengthens the
thread in three ways: tension, shear, and fatigue resistance. The rubber
component is covered by an oil shield to protect the rubber from
petroleum based products.
