![]() Since greater efficiency can only be accomplished by increasing deflection, when double deflection was needed, two mountings were bolted together. As foolish as it seems now, we cemented a rubber pad to the baseplate to provide friction. Both the base plate and the upper tapped washer were exposed and they corroded. The general configuration of our N mountings was known, but all mountings were manufactured as at the right and seldom taller than 1”. Super W pads feature unique waffle pockets which allow for greater deformation of the material, providing excellent isolation performance. When loaded conservatively, the load deflection curve is similar to the straight line shear. This sub-base should be 12 (305mm) thick and 12 (305mm) longer and wider than the mechanical equipment above it. Compression mountings are less expensive for a given capacity and when overloaded, there is still a cushion. When floors or roofs are lighter than 4 (102mm) solid concrete, it is desirable to introduce a localized mass under the vibration mountings in the form of a sub-base. When overloaded, the mountings would bottom out. The deflection can be used directly in the frequency equation after dynamic stiffness correction. Unfortunately, shear mountings could and did fail because of bond failure between the rubber and metal. Shear loading curves are straight line similar to steel springs.

Mountings were circular or sold in long strips, so the capacity could be controlled by size and durometer, or durometer and the cut off length. Waffle Vibration Isolator Pads - Grainger Industrial Supply When it comes to Waffle Vibration Isolator Pads, you can count on Grainger. Up until the 1950’s most rubber mountings were designed to take the load in shear. At SoundAway, we offer the 1 x 4 x 4 TriCore rubber foam pads for reducing vibrations from compressors, generators, pumps, & more.
