Vibration isolator DVA.5-40-20-M8-70 Z050599

Vibration Isolators – Reduction of Vibrations and Noise

The DVA.5-40-20-M8-70 vibration isolator is an element designed to effectively dampen vibrations and reduce noise generated by machines and equipment. Its construction is based on a combination of a galvanized steel insert and a rubber body, which provides effective isolation from the substrate or other structural elements. Mounting is done using an M8 metric thread, and the whole is characterized by compact dimensions – diameter 40 mm and height 20 mm.

This type of vibration isolators finds wide application in many industries, where vibration reduction is crucial for improving working comfort, increasing machine durability, and minimizing the risk of damage. They are ideal for mounting motors, pumps, fans, as well as for isolating enclosures and electrical cabinets. By absorbing vibration energy, they contribute to quieter operation of devices and reduced mechanical stress on their components.

Construction and properties

The DVA.5-40-20-M8-70 vibration isolator consists of a galvanized steel insert with a threaded (non-through) hole and a body made of natural rubber with a hardness of 70 degrees on the Shore A scale. The hardness of the rubber has a significant impact on the damping properties – higher hardness means greater stiffness and better handling of larger loads, while lower hardness provides better isolation at smaller loads. Choosing the appropriate rubber hardness allows you to adapt the vibration isolator to specific application requirements.

The construction with an internal M8 thread enables easy and secure mounting in threaded holes. The steel insert provides mechanical strength and corrosion resistance (thanks to galvanizing), while the natural rubber is characterized by high internal damping and sound absorption capacity. This selection of materials guarantees long-lasting and reliable operation in various environmental conditions.

Application and benefits

By choosing DVA.5-40-20-M8-70 vibration isolators you gain:

• Effective vibration damping: Reduction of transmitted vibrations protects machines from damage and extends their service life.
• Noise reduction: Reducing the noise level generated by devices improves operator comfort and meets safety standards.
• Easy installation: M8 thread allows for quick and easy installation without the need for additional tools.
• Durable construction: The combination of galvanized steel and natural rubber provides resistance to corrosion and long-term operation.
• Versatile application: Possibility of use in various industries and for isolating various types of equipment (motors, pumps, fans, etc.).
• Protection against damage: Shock absorption protects delicate machine components from mechanical damage.
