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

Vibration isolator DVA.1-15-20-M4-10-55 is an element designed to dampen vibrations and reduce noise generated by machines and equipment. Its construction, based on a combination of galvanized steel and natural rubber, provides effective isolation from vibrations, which translates to increased work comfort, extended equipment life, and improved safety. It is a universal solution, finding application both in industrial installations and in everyday devices.

Construction and application

Vibration isolator DVA.1 is characterized by a cylindrical construction with a threaded steel pin (galvanized) and a damping body made of natural rubber. The external thread with a size of M4 allows for easy mounting in various structures. This specific model (DVA.1-15-20-M4-10-55) has a diameter of 15 mm, a height of 20 mm, and a rubber hardness of 55 degrees on the Shore A scale. This hardness provides a good compromise between vibration damping and structural stability.

Vibration isolators of this type are widely used when mounting components of devices such as motors, fans, or pumps. They are also used to isolate machine housings, electrical cabinets, and other elements sensitive to vibrations. Thanks to them, it is possible to minimize the transfer of vibrations to the surroundings, which is particularly important in environments requiring quiet operation and precision.

Advantages and benefits

• Effective vibration reduction: Natural rubber with a hardness of 55 Shore A effectively absorbs vibration energy, minimizing its transfer to the device or foundation structure.
• Versatility: Possibility of use in various types of machines and equipment thanks to the standard M4 thread and compact dimensions.
• Durable construction: Galvanized steel provides corrosion resistance, and natural rubber is characterized by high fatigue strength and elasticity.
• Easy installation: The threaded pin facilitates quick and secure mounting in prepared holes.
• Improved work comfort: Reduction of noise and vibrations translates to better working conditions for machine and equipment operators.
• Extended service life: Vibration damping reduces mechanical loads on structural elements, which contributes to extending their service life.
• Availability of different rubber hardnesses: The ability to choose the appropriate rubber hardness (40, 55 or 70 Shore A) allows for optimal adaptation of the vibration isolator to specific application requirements.
• Temperature resistance: Natural rubber retains its properties over a wide temperature range (-40°C to +80°C).
