What are rubber vibrations mounts?

Rubber anti-vibration mounts, rubber vibration dampers and rubber isolation mounts are all used for the same purpose that is isolation of high frequency noise and vibration. In any industry a large machine such as a pump, compressor or industrial engine produces noise and vibrations. These vibrations can cause damage to equipment, prematurely wear out machines and create unsafe working conditions. Eventually this can affect the product quality and can even bring plant production to a complete stall. To protect your machinery, from such damage, rubber isolation mounts are necessary. These devices help reduce the amplitude and frequency of the vibration created by the machinery.

A properly sized rubber anti-vibration mounts will significantly reduce the vibration, shock and noise created by the machine thus increasing the life span of the machine.  These vibration rubber mounts creates a resilient connection to the machine and transfers the energy from the machine onto the mount which thus dampens the vibrations and shocks. Vibration damping mounts are commonly made with an elastomeric such as natural rubber which is bonded to a metal. This rubber vibration mount is then attached to a machine such as a generator that helps lower the natural frequency of the machine below the disturbing frequency, all without affecting the performance of the machine.

While an inappropriate sized mount might reduce the higher frequency vibration or noise, but the lower frequency conditions may amplify, resulting in worsening the condition. Hence it is important to select the right anti-vibration mount for your application.

Vibration mounts come in a wide variety of range. So, depending on your application in use one must accordingly select the right vibration mounts. For instance marine engine mounts are used as rubber vibration isolators in industrial applications such as diesel generators and engines. While, rubber cylindrical mounts also known as rubber bobbin mounts are used in light weight applications for isolation of shocks and vibrations.

The Common applications of rubber vibration mounts are pumps, roll mills, CNC machinery, military equipment, washing machines, industrial engines, HVAC systems, Aviation equipment, compressors, shipping containers, defense equipment and much more.

Vibration damping and isolation are the need of the hour

The rubber anti-vibration mounts and isolators have become a standard requirement as more and more people are becoming aware of the adverse effects of vibration and noise. Today, the isolation mounts are being widely used in refrigeration plants, compressors, HVAC equipment, diesel generators, fans, motors, pumps, presses and CNC machines etc. The elastomer can be natural rubber, neoprene or other compound depending on the requirement of resistance to ageing, compression set, water and oil. Let us take a look at the variety of the anti-vibration mounts and rubber hangers available.

Rubber grommets: The rubber grommet isolators provide the economical vibration isolation for light loads. The rubber bushings and rubber grommets are ideally suited for computers, disc drives, sensitive lab equipment and precision instrumentation.

Rubber bobbins: The rubber cylindrical mounts are also known as bobbin mounts and are used to curb both active and passive vibrations. The rubber dampers are effective in structure-borne noise control. A variety of combinations involving the stud and threaded hole at the two ends of the cylinder are available.

Rubber fan mounts: To prevent the transmission of vibrations from a fan motor to travel to the chassis, on which it is mounted, requires a rubber isolation mount to be put into place. The anti-vibration fan mount can be made from silicone and other rubber compounds in order to decouple the fan from the case and also attenuate the unwanted vibration.

a coil spring and carbon steel bases are ideally suited for mounting of HVAC equipment like fans, AHUs, pumps, and motors. The rubber in shear isolators is also used for HVAC applications where a higher degree of stiffness is required in the horizontal plane and good isolation in the vertical plane. Thus, the rubber in shear vibration isolators provides a cost effective engineered solution for HVAC equipment mounting.

Hard rubber mounts: The hard rubber mounts are desired for high reliability and fine quality requirements. The hard rubber anti-vibration mounts are custom built and find the usage in automobiles, machinery and household electrical appliances etc.

Rubber hangers: The anti-vibration hangers are used for false ceiling suspension, HVAC ducting and piping suspension, and equipment suspension. The rubber hangers are primarily made from polymer material while the spring hangers make use of metal springs.

Anti-vibration motor mounts: The equipment like hexacopters and multi-rotors make use of the anti-vibration motor mounts to attenuate the vibration and noise from motors and props. The flight controller sensors function properly only when the rubber anti-vibration mounts significantly dampen the motor vibrations.

Andre HVAC International Inc. is a leading supplier of rubber isolation mounts, rubber bushings, and HVAC rubber mounts to name a few. AHI uses the best of material to provide a long service life and enhance the life of the equipment. Whether you are replacing a worn out mount or going in for a new application, AHI has the right anti-vibration mounting to give you the desired vibration isolation and noise reduction.


What are rubber mounts and why are they considered to be better vibration isolators than the rest?

Anti-vibration rubber mounts are critical components in a number of heavy machinery and industrial equipment’s. These rubber dampening vibration mounts help dampen the high frequency noise levels and vibration while safeguarding fragile components from external vibrations. Rubber isolator mounts are an efficient, low cost option, offering a reasonable degree of isolation efficiency. These rubber mountings come in single of double deflection and are effective isolators in standard non-critical applications. While for more critical applications, one can consider using rubber hangers or spring hangers or mounts for vibration isolation.

Selecting the right anti-vibration rubber mounts is critical to tackle the problem of vibration What are rubber mounts and why are theyconsidered to be better vibration isolators than the rest?and noise. One should determine the machine’s RPM and use the Rubber Mount Isolation Efficiency Chart to work out the dynamic natural frequency required, according to the desired isolation efficiency. Also, it would be quite beneficial if one refer to the Rubber Mount Selection Guide to determine the static deflection required, depending on the various dynamic factor of the rubber mount that are to be used.

A high quality rubber anti-vibration mounts are scientifically designed resilient material. They are designed in a way to offset the high frequency noise and absorb the vibration and shock through the rubber when under load while maintaining lateral stability. This design eliminates the shape factor that is usually associated with elastomeric pads. It also provides positive grip to machine foot and foundation when under load. It can be used in any shape/ size/ thickness/ number of layers. These rubber in shear mounts or rubber isolation pads are ideal for isolating the vibration and shock while also effectively reduce the structure borne noise.

These rubber mounting come in a variety of single and double deflection rubber in shear ANDRE-RubberHangers-RHM-Series (1)hangers that are perfect for not only heavy machines but also very practical to install in almost any type and size of equipment such as machine tools, generating sets, compressors, pumping sets, instrument panels etc. It is very effective for protecting precision equipment’s and instruments from external sources of vibration and shock caused by operation of heavy machines, mechanical handling equipment, forging hammers and even passing traffic.

Rubber anti-vibration mounts are typically used in a wide variety of applications that include the following

  • Air conditioning equipment’s,
  • Guillotines,
  • Grinders, headers,
  • Heating and ventilating equipment,
  •  Inertia blocks,
  • Instruments panels,
  • Impact machines, laboratory equipment’s and machine tools,
  • Pumps, printing machines, presses,
  • Textile machinery and transformers and many more of such applications.
