Step By Step Guide To Choosing Anti-Vibration Mounts

With so many anti-vibration mounts on the market, it’s hard to know which is the best for your machinery to ensure smooth running, prolong lifespan and reduce the risk of damage. Machinery vibration from equipment can be transferred to the supporting structure and travel large distances to be emitted as noise elsewhere in a building or structure. Rubber mounts prevent the transfer of these vibrations the machines generate. As a leading specialist in anti-vibration mounts, we offer our extensive expertise using a step by step guide to help you choose the correct rubber mounts.

  1. Identify the total weight (kg) of the equipment/machinery and the number of mountings that’ll be required.

The larger the total weight, the larger the mountings or the higher the number of mountings needed to reduce the machine vibrations.

  1. Calculate the weight of each mounting. Make sure to consider that the weight on the machinery may not be evenly distributed.

For example, if the machinery weighs 340 kg, the equipment would require rubber mounts with a weight of 85 kg each if 4 mounts were purchased to evenly distribute the weight. Check the center of gravity to ensure an even distribution of load as different mounts may be required in different locations.

  1. Measure the running speed of the machinery.

Calculate the normal running speed of the machinery, referred to as the forcing frequency and also the lowest operating speed (normally at idle).

  1. Determine the static deflection of the mounting.

Static deflection is simply the amount that a mount compresses under the weight of the equipment. The more static deflection, the more work the mount has to do. For example, if a spring is 10 cm high when unloaded and compresses to 9 cm when carrying the weight of the equipment the static deflection is 1 cm.  This is how static deflection is calculated.

  1. Based on the load per mounting, select a suitable mounting type to give the required static deflection.

    Take into account specific application requirements and the reduction in vibration required. Graphs showing vibration isolation against deflection can be used to determine the levels of vibration reduction – contact us for guidance/details.

  2. Ensure all connections and services to equipment, like the exhausts, pipework and ducting are flexible in order for the machinery to move freely.

Anti-vibration mounts have a number of benefits and offer great overall value for money. They not only serve to protect the machinery by reducing the impact of machines power, but also benefit the life of equipment, vehicles and structures. Without rubber mounts on the machinery, the sheer impact of the vibrations can cause weakening and even result in failure. It is therefore crucial to not only protect your equipment but also the well-being of the workers using the machinery with suitable mountings. The mounts are easy to install and are available in a variety of sizes, designs and load capabilities.
