Vibration isolator DVA.4-30-17-M8-20-55 Z030977

Vibration damping and noise reduction with DVA vibration isolator.4

The DVA.4-30-17-M8-20-55 vibration isolator is an element designed for effective vibration damping and noise reduction in machines and equipment. It is a key solution wherever operator comfort, safety and equipment life are a priority. The construction based on rubber with a specific hardness allows for the absorption of vibration energy, minimizing its transfer to the environment or sensitive components.

Construction and application

This vibration isolator is characterized by a cylindrical shape and an external M8 thread, which facilitates installation and integration with various structures. A diameter of 30 mm and a height of 17 mm ensure stability and efficiency. Made of galvanized steel, it guarantees corrosion resistance and durability even in harsh environmental conditions. Vibration isolators from the DVA.4 series are widely used as shock absorbers, cushioning pads and for mounting smaller mass devices. They are perfect for mounting motors, pumps, fans or other components generating vibrations.

Choosing the right rubber hardness

The rubber hardness on the Shore A scale is 55, which is a compromise between vibration damping and the load-bearing capacity of the element. Choosing the right hardness is crucial for optimal operation of the vibration isolator - the higher the hardness, the greater the load capacity, but the less vibration damping, and vice versa. Other rubber hardnesses (40, 70±5) are also available, which can be ordered for specific applications. This allows you to adapt the properties of the vibration isolator to specific application requirements.

It is worth remembering that the correct selection of a vibration isolator takes into account the frequency of vibrations, the load and the required degree of damping. Elesa+Ganter offers technical support in the selection of appropriate insulating elements.
