Anti vibration mounts are specialized components used to isolate equipment from shock, vibration, and noise. In industries such as automotive, HVAC, and heavy machinery, excessive vibration can lead to equipment failure, reduced performance, and safety concerns. In this guide, we’ll explore everything you need to know about anti vibration mounting systems.
What Are Anti Vibration Mounts?
Anti-vibration mounts, also known as vibration isolators or shock mounts, are mechanical devices designed to reduce or isolate vibrations in machinery, equipment, and structures. They serve to minimize the transmission of vibrations from one component to another, thereby preventing damage, reducing noise, and improving the overall performance and longevity of the system.
Why Is Anti Vibration Mount Important?
Anti vibration mounts offer several key benefits:
Reduce Noise and Vibration Transmission
Their primary purpose is to absorb and isolate vibrations generated by machinery, preventing the transfer of those vibrations to surrounding structures or equipment. This reduces noise levels and protects against damage from excessive vibrations.
Extend Equipment Lifespan
By minimizing vibrations, anti-vibration mounts help prevent issues like loosening of bolts, loss of production, malfunctions, and premature wear and tear on machinery components like gears and bearings. This extends the overall lifespan of the equipment.
Improve Performance
Anti vibration mounts stabilize equipment, ensuring smoother operation, higher precision, and better overall performance.
Improve Production Quality
Vibrations can negatively impact the performance of machinery by causing misalignment, resonance, or reduced accuracy. Sensitive equipment like CNC machines, CMMs, and other precision instruments require minimal vibrations for accurate measurements and high-quality output. Anti-vibration mounts facilitate this by isolating vibrations.
Enhance Worker Safety and Comfort
Excessive vibrations can lead to operator fatigue, mistakes, and even accidents. Mounts reduce vibration exposure, improving worker health, safety, and productivity.
Comply with Regulations
Using anti vibration mounts helps fulfill OSHA regulations on anchoring fixed machinery and controlling vibration exposure as per ergonomic guidelines.
Versatility and Durability
Available in various materials like rubber, thermoplastic elastomers, and metal-rubber combinations, anti-vibration mounts are durable and suitable for diverse industrial applications across different load capacities.
What Materials Are Used to Make Anti Vibration Rubber Mounts?
Anti-vibration mounts are typically made from the following materials due to their excellent vibration damping and shock absorption properties:
Rubber
Rubber, particularly natural rubber and synthetic rubbers like nitrile (Buna-N), styrene-butadiene (SBR), and neoprene, are widely used for manufacturing anti-vibration mounts. Rubber’s inherent elasticity and ability to dissipate vibrational energy make it an ideal choice.
Thermoplastic Elastomers (TPE)
TPEs are a family of rubber-like materials that combine the properties of thermoplastics and elastomers. They offer good vibration isolation capabilities along with durability and resistance to environmental factors.
Silicone Rubber
Silicone rubber is another popular material for anti-vibration mounts due to its excellent thermal stability, resistance to aging, and ability to maintain its properties over a wide temperature range.
Rubber-Metal Combinations
In some cases, rubber is combined with metal components like steel to create anti-vibration mounts with enhanced load-bearing capacity and durability, such as wire rope mounts or sandwich mounts.
Visco-Elastic Polymers
Specialized visco-elastic polymers like Sorbothane are also used in high-performance anti-vibration mounts due to their unique ability to dissipate vibrational energy over a wide temperature and frequency range.
The choice of material depends on factors such as the operating environment, temperature range, load requirements, and the desired level of vibration isolation.
Types of Anti Vibration Mounts
Types of Anti Vibration Mounts
Using the correct type of anti vibration mount helps extend equipment life and minimize the effects of vibration, noise, and shock. We provide a variety of custom rubber mounts to suit different applications, from light-duty machines to heavy industrial systems.
Cylindrical Mounts (Rubber Bobbin Mounts)
Used for noise damping and effective vibration absorption in a wide range of applications. It can isolate both passive and active vibrations. Made of premium quality natural rubber and steel metal.
Conical Mounts (Rubber Cone Mounts)
Help isolate vibration and shock in machinery. That can carry high loads and provide stable vibration/noise reduction. Offer protection against extreme loads in tension, compression, and excessive forces.
Bushing Mounts (Center Bonded Bushings)
Made of bonded rubber and metal. Minimize static and dynamic vibrations. Suitable for high-frequency noise and vibration reduction while supporting high loads.
Sandwich Mounts
Provide support and rubber isolation for instruments and engine suspension. Reduce noise, vibration, and enhance equipment longevity. Used in automotive, railways, construction equipment, and heavy vehicles.
Rubber Levelling Mounts
Don’t need to be fixed to the supporting structure. Suitable for outdoor ACUs, axial/radial fans, motors, pumps, and compressors.
Spring Mounts
Used for low-frequency vibration damping in slow-speed rotating equipment. That can have individual, multiple open springs or encased spring designs. Spring mounts offer excellent vibration isolation across a broad frequency spectrum and are commonly used in HVAC equipment, generators, compressors, and heavy machinery.
Bell-Shaped Elastomer Mounts
Suitable for machinery with radial vibration and high-frequency applications. Ideal for equipment prone to starts and stops.
Rubber Hangers
Used in ventilation and AC systems to absorb suspended load vibrations. Adjustable for sloping ceilings.
Rubber Pads
Rubber pads are simple yet effective anti-vibration solutions used to isolate machinery or equipment from surfaces such as floors or platforms. They are placed beneath the equipment to absorb vibrations and prevent them from transmitting to the surrounding environment.
Enclosed Captive Mounts
Designed with a built-in enclosure to limit excessive movement during operation. These mounts are ideal for applications with high shock loads or mobile equipment where safety and stability are critical. Commonly used in off-road vehicles, marine engines, and military-grade machinery.
Air Spring Mounts
Use compressed air to isolate low-frequency vibrations in sensitive equipment. They offer excellent height adjustability and load compensation, making them suitable for high-precision machines, testing systems, and laboratory instruments. Ideal for applications requiring superior vibration isolation across a broad frequency range.

How to Choose An Anti Vibration Mounting?
Choosing the right anti vibration mount is essential to protect your equipment and ensure smooth operation. Here are six practical steps to guide your decision:
- Determine the Equipment Weight and Number of Mounts
First, find out how heavy your equipment is and how many mounts you will use. Divide the total weight by the number of mounts to understand how much load each mount must support. This helps you choose mounts that can carry the load safely and evenly.
- Understand the Required Static Deflection
Static deflection is how much the mount compresses under the equipment’s weight. More deflection means better vibration absorption, especially for machines with low-frequency vibrations. Check the mount’s specifications to find the right deflection level.
- Know the Operating Speed (RPM) or Frequency
The machine’s operating speed affects vibration patterns. Knowing the RPM helps you select mounts that reduce vibrations effectively and avoid resonance that can cause damage.
- Verify the Load Is Within the Mount’s Working Range
Each mount has a load capacity range. Too much weight can crush the mount (bottoming out), while too little load reduces vibration isolation efficiency. Always choose mounts rated for your equipment’s actual load.
- Select the Mount Type Based on Your Application
Different mount types fit different needs. Consider your equipment’s size, installation space, and vibration type when choosing.
- Consider Installation and Adjustment Needs
Some mounts are easier to install and adjust than others. For uneven floors or sloped ceilings, adjustable or leveling mounts may be necessary to ensure proper isolation and balance.
