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

Vibration isolator DVA.4-20-30-M6-18-55 is an element designed to dampen vibrations and reduce noise generated by machines and equipment. Its construction allows for isolating the vibrating mass from the environment, which translates to improved work comfort, increased device life, and reduced risk of damage resulting from vibrations. This is particularly important in applications where precision and noise minimization are key.

Construction and application

This specific model, with a diameter of 20 mm and a height of 30 mm, features a cylindrical design and an external M6 thread. It is made of galvanized steel, which ensures corrosion resistance and durability in various environmental conditions. The DVA.4 vibration isolator is primarily used for mounting components such as motors, fans, or pumps, as well as an element for absorbing impacts and shocks. Therefore, it works well both in industry and in home or workshop applications.

Characteristics and benefits

Choosing the right vibration isolator is crucial for the effectiveness of vibration damping. The DVA.4 model has a rubber hardness of 55 on the Shore scale, which provides optimal damping properties for a wide range of loads and vibration frequencies. This hardness allows for effective absorption of vibration energy, minimizing its transfer to the device structure or foundation. Additionally, the use of rubber as a damping material provides corrosion resistance and high fatigue strength – features important for long-term operation.

• Effective noise reduction: Reducing the noise level generated by operating machines improves operator comfort and meets safety standards.
• Protection against damage: Damping vibrations minimizes the risk of damage to structural elements caused by resonance or material fatigue.
• Extended device life: Reducing dynamic loads translates to a longer service life of machines and equipment.
• Easy installation: The external M6 thread facilitates quick and secure installation in standard threaded holes.
• Corrosion resistance: Galvanized steel ensures durability even in harsh environmental conditions.
• Optimal hardness: A hardness of 55 Shore'a provides good damping properties while maintaining adequate stiffness.

The selection of the appropriate vibration isolator should take into account the vibration frequency, load, and required degree of damping – detailed information on selection can be found in the technical documentation of Elesa+Ganter Polska.
