Vibration isolator DVA.5-20-25-M6-55 Z031004

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

Vibration isolators from the DVA.5 series are resilient-damping elements designed to reduce vibrations and noise generated by machines and equipment. Their task is to isolate the vibrating mass from the environment, which translates to improved work comfort, increased safety, and extended equipment life. They are particularly useful in situations where it is necessary to minimize the transmission of vibrations to building structures or other sensitive elements.

Construction and application

Vibration isolator DVA.5-20-25-M6-55 consists of a galvanized steel insert with a threaded (non-through) hole and a damping body made of natural rubber. The M6 thread allows for easy mounting in many applications. This particular model is characterized by a diameter of 20 mm and a height of 25 mm, and the rubber hardness is 55 on the Shore A scale ±5. Thanks to this combination of materials and construction, the vibration isolator effectively absorbs vibration energy, minimizing its negative impact.

DVA.5 vibration isolators find wide application in various industries – from agricultural machinery, through industrial equipment, to precision equipment. They are ideal for mounting motors, pumps, fans and other vibration-generating elements. They can also be used to isolate enclosures and electrical cabinets from external vibrations.

Key features and benefits

• Effective vibration reduction: Natural rubber with a hardness of 55 Shore A provides optimal vibration damping over a wide frequency range.
• Durable construction: Galvanized steel insert guarantees corrosion resistance and long-term operation.
• Easy installation: M6 thread facilitates quick and secure mounting in various applications.
• Versatile application: Suitable for isolating various types of machines and equipment, both portable and stationary.
• Improved work comfort: Vibration reduction translates to quieter operation of machines and equipment, which improves operator comfort.
• Increased equipment life: Damping vibrations reduces mechanical loads on structural elements, which extends their life.
• Universality: Can be used both as an element isolating the machine from the ground (active vibration isolation) and isolating the machine from vibrations coming from the environment (passive vibration isolation).

The selection of the appropriate vibration isolator should take into account the vibration frequency, static load and the required degree of damping – accurate information about these parameters will allow for optimal adaptation of the element to a specific application.
