The choice of rubber isolators for a specific application, system, or piece of equipment or machinery depends on several factors. Making the right choice will ensure the anti-vibration device is effective and functions as intended. Choosing incorrectly will result in poor vibration and noise control, increased risk of electrical current and shock transferring between parts and less protection for the two surfaces.
Taking the time to consider the specifics of the requirements for the isolator will always be an important starting point. Working with a manufacturing company specializing in rubber isolators will also be a critical factor for quality parts which are manufactured to stand up to demanding conditions.
The Size
The size of the isolator, which will include the thickness of the rubber and the shape of the isolator, will be directly related to the weight and shape of the sides of the equipment. Another factor which will come into play is where the center of gravity will be on the equipment and where the oscillators are located with respect to the center of gravity.
In most applications, the closer to the center of gravity, the greater the load capacity of the isolator. Additionally, the forces will reduce away from that center of gravity, allowing for different options in rubber isolators to accommodate for the higher or lower forces acting upon the specific area of the equipment.
Type of Vibration
The type of equipment will have an impact on the type of vibration or current to be isolated. Testing may need to be completed to understand the range of vibration, shock and electrical issues which need to be isolated on one side of the mount.
Ambient Conditions
Understanding additional factors, such a temperature range, and humidity will be critical in selecting the ideal component. While rubber is a practical option for many environments, there may be other options to consider in extremely high or low-temperature applications.
