A Rubber Isolator, otherwise referred to as a Vibration Isolator, commonly takes the form of a flexible elastomeric or steel spring element, and is designed to reduce the transmission of undesirable or harmful vibration from machines and other sources of vibration.

The vibration reduction, or “isolation efficiency” depends on the amount the isolator is compressed or stretched in its loaded condition – this is commonly referred to as the isolator “static displacement” where greater displacement leads to better isolation.
