DESCRIPTION

R & D Marine 5" x 2.44" Shear Loaded "Super Mounts". The R & D Shear Mount is a low height rectangular mounting giving the best combination of lateral stiffness. Designed for marine use, accepts propeller and engine thrust in both directions.

  • Offers a fail safe design
  • R & D Mounts are height adjustable
  • Pre-loaded to reduce movement (0.09)
  • Slotted holes in base to assist in alignment
  • Mount types to fit all applications

Note: Capacity is calculated by engine weight divided by the number of mounts used.

    Direction A- soft to isolate vibration
    Direction B- soft to isolate vibration at right angles to crankshaft
    Direction C- stiff to take propeller thrust
The R & D Engine Mounts are designed specifically for the rigors of marine applications. The mounts are stiff enough to absorb forward and reverse propeller thrust, yet soft enough to isolate drivetrain vibrations from the hull. To help increase the longevity of the mounts, all steel parts are zinc plated and pasivated to limit corrosion. The rubber component is covered by an oil shield to protect it from petroleum based products.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.
