Vibration isolator DVA.3-75-55-M12-70 Z049833

Vibration and Noise Reduction with DVA.3 Isolator

The DVA.3-75-55-M12-70 vibration isolator is designed for effective vibration damping and noise reduction generated by machinery and equipment. Its construction, based on a flexible rubber material with a hardness of 70 Shore A, allows for the absorption of vibration energy, minimizing its transmission to the environment or substrate. This translates to improved working comfort, increased safety, and extended equipment life.

This model, characterized by a cylindrical shape and a diameter of 75 mm, is particularly useful in applications requiring the mounting of components such as motors, fans, or pumps. M12 threaded connections provide stable and secure mounting, and the galvanized steel insert guarantees corrosion resistance and durability. The DVA.3 isolator is part of a wide range of products offered by ELESA+GANTER, specializing in standard machine elements – known for their high quality and precision.

Construction and Application

The DVA.3 vibration isolator has been designed with versatility in mind. Its construction is based on a combination of a rubber damping element and a metal insert providing mechanical strength and mounting capability. The rubber hardness (70 Shore A) has been selected to provide optimal vibration damping while maintaining adequate load capacity. This makes the vibration isolator suitable for a variety of industrial and machine applications.

• Noise Reduction: Absorbs vibration energy, reducing the noise level generated by operating machines.
• Protection against Damage: Dampens vibrations, protecting delicate components from damage caused by resonant vibrations.
• Extended Service Life: Reduces dynamic loads on structural elements, which translates to a longer service life of equipment.
• Working Comfort: Improves working conditions for operators by reducing vibrations transmitted to the workstation.
• Easy Installation: M12 threaded connections allow for quick and easy installation in standard threaded holes.

Selection and Material Properties

Choosing the right vibration isolator is crucial for achieving optimal vibration damping effects. The hardness of the rubber has a direct impact on the damping characteristics – the softer the rubber, the better the damping at lower frequencies, but the lower the load capacity. In the case of DVA.3-75-55-M12-70, a hardness of 70 Shore A represents a compromise between damping and load capacity, making it a universal solution for many applications.

The rubber is characterized by high internal damping and sound absorption capacity – these properties are used in vibration isolators to effectively reduce both mechanical vibrations and airborne noise. The steel insert provides dimensional stability and resistance to static and dynamic loads. Galvanization protects the metal from corrosion, which is particularly important in harsh environmental conditions.
