Rubber dampers

Rubber dampers for effective reduction of vibration, noise and impact

Rubber dampers are key machine elements for effectively reducing vibration, impact and noise in a wide range of industrial applications. By absorbing mechanical loads, they protect machinery, extend component service life and improve operational safety and reliability. Our range includes high-quality rubber dampers in various shapes, dimensions, threaded versions and types from renowned manufacturers such as Dichta, Elesa and BEA, meeting the requirements of mechanical engineering, the automotive industry, agricultural machinery and many other fields.

What are rubber dampers and how do they work?

Rubber dampers, often also referred to as vibration dampers, rubber vibration dampers or rubber mounts, are elements made of elastomer (most commonly NBR rubber) bonded to one or two metal threaded connections. Their purpose is to absorb vibration, reduce mechanical shocks and prevent vibration transmission between two structural elements.
The elastic rubber part acts as a damping medium that effectively reduces the dynamic forces generated during machine operation. This reduces loads on the structure, improves equipment stability and extends the service life of the entire system.

Why use rubber dampers?

Industrial machines, electric motors, pumps and compressors generate vibration during operation, causing wear, noise and material fatigue. Rubber dampers effectively reduce these negative effects and enable smoother and more reliable equipment operation.
Their main advantages include:

• effective vibration damping,
• noise reduction,
• protection against mechanical shocks,
• reduced machine wear,
• greater structural stability,
• extended component service life,
• lower maintenance costs,
• greater operational safety.

These properties make them a standard solution in modern machine design.

Where are rubber dampers used?

Rubber dampers are used virtually anywhere vibration or mechanical shocks need to be prevented from passing between individual machine components.
The most common applications include:

• electric motors,
• pumps,
• compressors,
• fans,
• generator sets,
• generators,
• conveyor systems,
• industrial machines,
• CNC machines,
• air-conditioning units,
• cooling systems,
• automotive industry,
• agricultural machinery,
• construction machinery.

Their use improves operating comfort, reduces structural loads and increases equipment reliability.

Different types of rubber dampers for different requirements

Because individual applications have different requirements, numerous versions of rubber dampers are available.
Our range includes various types, such as:

• ST-1,
• ST-2,
• ST-3,
• ST-4,
• ST-5,
• GN 454,
• FD-M,
• FD-F,
• DH,
• SS,
• CM/P,
• elastomer buffer.

The individual types differ in mounting method, dimensions, load capacity and area of use, so it is important to select the appropriate model for the requirements of the application.

How to choose the right rubber damper?

When selecting the appropriate vibration damper, several factors must be considered, because an incorrect choice can reduce damping efficiency or shorten the service life of the element.
The most important criteria are:

• equipment weight,
• magnitude of dynamic loads,
• vibration frequency,
• mounting method,
• thread size,
• damper diameter and height,
• operating environment,
• operating temperature.

A correctly sized damper provides optimal vibration absorption and stable machine operation.

Advantages of NBR rubber in vibration dampers

Most rubber dampers in our range are made from high-quality NBR rubber, which offers excellent mechanical resistance and a long service life.
Advantages of NBR material include:

• good resistance to oils,
• resistance to fuels,
• high mechanical strength,
• good elasticity,
• wear resistance,
• long service life,
• reliable operation under industrial conditions.

These properties make NBR one of the most commonly used elastomers for industrial vibration dampers.

Why is damper quality important?

Lower-quality dampers may lead to faster rubber ageing, cracking, loss of elasticity and consequently poorer vibration damping. This can result in increased bearing wear, cracks in the structure, higher noise levels and more frequent machine failures.
High-quality rubber dampers provide stable long-term operation even under high dynamic loads and demanding industrial conditions.

Ten most frequently asked questions:

1. What are rubber dampers and what are they used for?
Rubber dampers, also known as vibration dampers, are machine elements made of elastomer and metal fastening elements whose purpose is to reduce the transmission of vibration, impact and noise between two mechanical components. They are used to protect machines, equipment and structures from harmful dynamic loads and help extend the service life of mechanical assemblies.
2. Where are rubber dampers most commonly used?
Rubber dampers are used in many sectors, including mechanical engineering, the automotive industry, agricultural machinery, and the production of electric motors, pumps, compressors, fans, generator sets, conveyor systems, air-conditioning units and industrial production lines. They are suitable anywhere vibration must be reduced and structures protected against mechanical loads.
3. How do I choose the right rubber damper?
When selecting a rubber damper, the equipment weight, vibration magnitude and frequency, mounting method, damper dimensions, thread size and operating conditions must be considered. A correctly selected damper effectively absorbs vibration, improves machine stability and prevents premature component wear.
4. What is the difference between the different types of rubber dampers?
Different types, such as ST-1, ST-2, ST-3, ST-4 and ST-5, differ mainly in shape, mounting method, dimensions, load capacity and area of use. Some models have a thread on both sides, others have a thread and a bore, while some are intended for special applications. The choice depends on the machine design and the requirements of the individual application.
5. What material are rubber dampers made of?
Most rubber dampers are made from high-quality NBR rubber, which provides good resistance to oils, fuels, wear and mechanical loads. Thanks to its excellent elasticity, it effectively absorbs vibration and retains its properties even during long-term use in demanding industrial environments.
6. How do rubber dampers reduce noise and vibration?
The elastic rubber part absorbs the mechanical energy generated during machine operation and prevents it from being transmitted to the structure. This reduces both the noise level and vibration intensity, improves equipment stability and reduces the load on bearings, bolts and other mechanical elements.
7. Are rubber dampers suitable for demanding industrial conditions?
Yes. High-quality rubber dampers are designed for demanding industrial environments where they are exposed to continuous vibration, mechanical loads and various environmental influences. When correctly selected and installed, they provide a long service life and reliable operation even under intensive use.
8. How often should rubber dampers be inspected or replaced?
It is advisable to inspect vibration dampers regularly as part of machine maintenance. If cracks, deformation, loss of elasticity or damage to metal fastening components are observed, replacement is recommended. Timely replacement helps prevent machine damage and reduces the risk of unplanned production downtime.
