Vibration isolator DVA.5-15-20-M4-70 Z050590

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 use translates to improved work comfort, increased safety, and extended equipment life. They are particularly useful in situations where it is necessary to isolate the device from the substrate or minimize the impact of vibrations on the surroundings.

Design and application

The DVA.5-15-20-M4-70 vibration isolator consists of a galvanized steel insert with a threaded (non-through) hole and a damping body made of natural rubber. The internal M4 thread allows for easy mounting in the device structure. This particular model is characterized by a diameter of 15 mm and a height of 20 mm, making it suitable for applications requiring compact solutions. Rubber hardness at 70 on the Shore A scale provides good resistance to loads and effective vibration damping.

DVA.5 vibration isolators find wide application in various industries, including:

• Mounting electric motors and pumps
• Isolation of fans and compressors
• Damping vibrations in precision equipment
• Noise reduction in machine housings
• Mounting vibration-sensitive elements, such as control cabinets

Characteristics and benefits

The use of DVA.5 vibration isolators translates into a number of benefits:

• Effective vibration reduction: Minimizes the transfer of vibrations to the device structure or substrate, improving stability and work accuracy.
• Noise reduction: Dampens sounds generated by operating machines, creating a more comfortable working environment.
• Extended service life: Reducing dynamic loads on structural elements leads to their longer use.
• Easy installation: The threaded hole allows for quick and convenient installation without the need for additional tools.
• Corrosion resistance: Galvanized steel provides protection against atmospheric influences and corrosion.
• Availability of different rubber hardnesses: Allows you to match the damping properties to specific application requirements (available hardnesses 40, 55 or 70 ± according to the Shore A scale).

Selecting the appropriate rubber hardness is crucial for optimal isolation efficiency – the greater the load, the higher the rubber hardness should usually be. It is worth remembering that rubber is characterized by high internal damping and the ability to absorb sound, making it an ideal material for this type of application.
