Vibration Isolators – Reduction of vibrations and noise in machines and equipment

Vibration isolator DVA.4-10-15-M4-10-55 is an element designed to dampen vibrations and reduce noise generated by machines and equipment. This is particularly important in working environments where operator comfort and safety are crucial, as well as for extending the lifespan of the machines themselves. Mounting vibration isolators between a vibrating machine and its foundation (active vibration isolation) or the substrate (passive vibration isolation) allows for isolating vibrations and minimizing their negative impact.

Construction and application

This specific model, DVA.4, is characterized by a cylindrical design and is widely used for damping impacts and positioning devices with lower mass. It has an external M4 thread, which facilitates mounting in various applications. It is made of galvanized steel, which ensures corrosion resistance and durability. This vibration isolator finds application in many industries, e.g. in the production of machines, industrial equipment, and in construction – e.g. when mounting ventilation or air conditioning elements.

Material and properties

A key feature of this vibration isolator is the use of rubber with a hardness of 55 on the Shore scale. The rubber is characterized by high internal damping, sound absorption capacity and good shape resilience. A hardness of 55 Shore'a provides a compromise between vibration damping and the load-bearing capacity of the element. Choosing the right rubber hardness is crucial for effective vibration isolation – the higher the frequency of vibrations, the harder the rubber should be. It is worth remembering that rubber does not corrode and is characterized by high fatigue strength, which translates into a long service life of the vibration isolator. The diameter of the vibration isolator is 10 mm and its height is 15 mm.
