Vibration isolator DVA.2-30-20-M8-20-55 Z030913

Vibration Isolators – Reduction of Vibrations and Noise in Machines and Equipment

The DVA.2-30-20-M8-20-55 vibration isolator 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 in many industries – from manufacturing to construction.

Construction and Application

The vibration isolator consists of a threaded pin and a molded insert with a non-through threaded hole, made of galvanized steel. The damping element is a body made of natural rubber with a hardness of 55 on the Shore A scale. This combination of materials ensures both mechanical strength and effectiveness in damping vibrations. External and internal threads allow for easy mounting in various structures.

In practice, these types of vibration isolators are used to mount components of devices, such as motors, fans, or pumps. They will also be useful wherever it is necessary to isolate elements sensitive to vibrations – e.g., electrical cabinets or precise measuring instruments. This minimizes the impact of negative vibrations on their operation.

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 guarantees corrosion resistance and long-term operation even in harsh environmental conditions.
• Easy installation: M8 threads facilitate quick and secure mounting in various applications.
• Versatility: Can be used in many types of machines and equipment – from light components to heavy structures.
• Improved work comfort: Reduction of noise and vibrations translates to better working conditions for machine operators.
• Extended equipment life: Damping vibrations reduces mechanical loads on structural elements, which affects their durability.
• Use of natural rubber: Natural rubber is characterized by high internal damping and sound absorption capacity, making it an ideal material for the production of vibration isolators.
• Resistance to weather conditions: Natural rubber retains its elastic properties over a wide temperature range (from -40°C to +80°C).

This vibration isolator has a diameter of 30 mm, a height of 20 mm, a metric thread size of 8, and a hardness of 55 on the Shore A scale.

The selection of the appropriate vibration isolator depends on the specifics of the application, the load, and the type of vibrations generated. Remember to consider these parameters when selecting the element to ensure optimal isolation efficiency.
