Vibration isolator DVA.4-30-17-M8-20-40 Z050435

Vibration isolators – reduction of vibrations and noise in machines and equipment

Vibration isolator DVA.4-30-17-M8-20-40 is an element designed to dampen vibrations and reduce noise generated by operating machines and equipment. Its construction based on rubber with a specific hardness allows for effective isolation of vibrations, which translates into increased work comfort, extended equipment life and improved safety. Mounted between the machine and its foundation, it absorbs vibration energy, minimizing its transfer to the surroundings.

Construction and application

This specific model, DVA.4, is characterized by a cylindrical structure and a threaded pin M8, which facilitates assembly and ensures a stable connection. The diameter of the vibration isolator is 30 mm, and the height is 17 mm. It is made of galvanized steel, which guarantees corrosion resistance and durability. Vibration isolators of this type find wide application in various industries – from agricultural machinery to precision laboratory equipment. They will work wherever vibration reduction is crucial for the proper functioning of equipment and operator comfort.

Selection of appropriate rubber hardness

The hardness of the rubber in this vibration isolator is 40 on the Shore A scale. This is a value that provides good flexibility and effective vibration damping under moderate loads. Choosing the right hardness is important – rubber that is too soft may not support the load, and rubber that is too hard will not provide sufficient insulation. It is worth remembering that Elesa+Ganter also offers other rubber hardnesses (55 or 70±5 according to Shore A), which can be ordered depending on the specific requirements of the application. This allows for precise matching of the vibration isolator to the characteristics of the vibrations and the load of the device.
