Vibration isolator DVA.4-30-15-M8-20-70 Z050572

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

Vibration isolator DVA.4-30-15-M8-20-70 is an element designed to dampen vibrations and reduce noise generated by operating machines and equipment. Its task is to isolate the vibrating mass from the surroundings, which translates to improved work comfort, increased safety, and extended equipment life. Mounted between the machine and the foundation, it absorbs vibration energy, minimizing its transfer to the building structure or other elements.

Construction and application

This specific model, DVA.4, is characterized by a cylindrical construction and has an external M8 thread for mounting. It is made of galvanized steel, which ensures corrosion resistance and durability. Its diameter is 30 mm, and its height is 15 mm. Vibration isolators from the DVA.4 series are particularly recommended for damping impacts and positioning devices with a smaller mass – from a few to several hundred kilograms. They find application in many industries, including the production of machines, ventilation equipment, pumps, and compressors. They are also used to insulate electrical cabinets or other elements sensitive to vibration.

Choosing the right hardness – key to effective isolation

Vibration isolator DVA.4 is available with rubber with a hardness of 70 on the Shore A scale. The hardness of the rubber is crucial for the effectiveness of the isolation – it affects the ability to absorb vibration energy and adapt to a specific load and vibration frequency. Higher hardness provides greater load capacity, while lower hardness provides better isolation at low frequencies. Selecting the appropriate hardness allows for precise adaptation of the vibration isolator to specific application requirements, ensuring optimal reduction of vibrations and noise.
