Vibration isolator DVA.3-20-25-M6-55 Z030941

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

The DVA.3-20-25-M6-55 vibration isolator is an element dedicated to damping vibrations and reducing noise generated by operating machines and equipment. Its use translates to improved work comfort, increased safety, and extended equipment life. This is particularly important in industrial environments, but also in applications where precision is key.

Design and application

This specific model, DVA.3, is characterized by a cylindrical design and an internal M6 thread on both sides. The diameter of the vibration isolator is 20 mm, and the height is 25 mm. It is made with steel inserts, galvanized to ensure corrosion resistance, making it suitable for use in various environmental conditions. The non-through threaded hole allows for stable mounting in the structure of the device or machine.

Vibration isolators of this type are widely used for mounting components such as motors, fans, or pumps. Thanks to their construction, they effectively absorb vibrations, preventing their transmission to the surroundings or other structural elements. This, in turn, minimizes the risk of mechanical damage and reduces noise levels.

Choosing the right hardness – the key to effectiveness

The hardness of the rubber in this model is 55 on the Shore A scale. This is an intermediate value that provides good damping properties while maintaining adequate load capacity. Choosing the rubber hardness is important – the softer the rubber (lower Shore value), the better the vibration damping, but the lower the load capacity. Conversely, harder rubber offers greater load capacity at the expense of slightly worse damping. Other rubber hardnesses (40, 70 ±5 according to Shore A) are also available, allowing you to adapt the vibration isolator to specific application requirements.
