For vibration isolation and shock reduction, engineers choose sandwich mounts. These mounts provide optimal vibration isolation, have high load carrying capacities, and are easy to install. The options may be overwhelming if you aren’t sure which mount to choose.
From elastomers to static load, there is a lot to think about. At RPM Industrial Rubber Parts, our team is ready to walk you through the options. Give us a call at (888) 842-5668. You can also take a look at our guide on selecting the right vibration isolation mount.
Whether choosing an existing sandwich mount or designing a brand new one, there are a few things to consider first.
Sandwich mounts are made of both rubber elastomers and metal. The metal is typically aluminum, steel or stainless steel. The elastomer, however, could be one of many different kinds. Here are some of the different types of elastomer that are used in sandwich mounts:
Depending on the elastomer of the sandwich mount, the final part will end up with specific capabilities.

This is one of the most important capabilities of a sandwich mount. These parts are extremely versatile and that means they are used in a variety of applications. They need to perform in heat, sunlight, and highly toxic environments. Sandwich mounts are incredibly versatile and are used in military, agricultural, construction, mining, oil, and gas environments. The sandwich mount should be able to withstand temperatures below 0º F and above 300º F.
Here are a few other environmental factors to consider:
Fluid is an especially important factor to consider. Parts inside of an automobile or machine are likely to be exposed to some kind of hydraulic fluid or oil.
The level of resistance to these factors lies in the chosen elastomer. Natural rubber, for example, is not able to withstand extremely high temperatures. Silicone, on the other hand, has high resistance in just about each one of these categories. Understanding how an elastomer reacts to environmental conditions is extremely important to how it performs. Be sure to choose a sandwich mount that works best for the desired application.
An important consideration when choosing a sandwich mount is the installation process and static load. When you meet with our RPM Industrial Rubber Part we will help determine how the mount will be installed. Using the data points that you provide such as static load and disturbing frequency, we can tell you exactly what mount you need.
Here are some data points from our Engineering Data for Vibration and Shock Isolator Questionnaire to get you started:
Take a look at our Selecting a Vibration Shock Isolator guide and scroll to Figure 13 for the full questionnaire. Knowing the answers to these kinds of questions will help you determine which sandwich mount is best.
There are many types of isolators that may be chosen for vibration damping. Choosing which one of these to use depends on the application and vibration requirements of the machinery. They include:
Fully bonded are the most popular type of isolator. These are also known as sandwich mounts. In addition to all of the isolators that are available, sandwich mounts alone have a few different kinds:
Each of these mounts is best for a specific use. For example, bobbin mounts may be used as a vibration foot or damper while square pad mounts are best for use in compression orientations.
Take a look at our Application Selection Guide to learn what kind of mount is best for your needs.
