Anti-vibration mounts (also known as vibration isolation mounts) are used to provide a resilient break when mechanical equipment is fixed rigidly to structures such as building floor slabs. This reduces the transmission of vibrations between the equipment and the structure, which can damage it, lead to noise pollution and make it uncomfortable to work around.
Anti vibration av mounts are available in a wide range of shapes and sizes, and they come with various features depending on the application. They can be found on everything from flanged engine mounts to rubber bushings, and are made from either natural or synthetic rubber. They are designed to withstand compression and shear loads, and can also absorb radial and axial forces. Some of them can even handle impacts and have good electrical properties.

The durometer of a rubber vibration mount is the main performance indicator, determining its spring rate and axial load capacity. A lower durometer means less vibration dampening, while a higher one indicates more rigidity.
Another factor to consider when selecting a vibration mount is its resistance to hot and cold environments. Generally speaking, natural rubber can withstand high temperatures for long periods of time, while NBR can tolerate short-term exposure to low temperatures.
The weight of the machinery you want to isolate will determine how much compression a vibration mount experiences, which is a key factor when choosing its size. The higher the machine’s weight, the more vibration isolation it will require.
