Vibration isolator DVA.1-20-25-M6-18-70 Z050492

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

The DVA.1-20-25-M6-18-70 vibration isolator is an element designed to dampen vibrations and reduce noise generated by operating machines and equipment. Its construction, based on a combination of galvanized steel and natural rubber, effectively isolates vibrations, protecting both the equipment itself and the surroundings. Mounting vibration isolators translates to extending the lifespan of machines and improving work comfort.

This specific model is characterized by a cylindrical structure, threaded external connections (both ends), and a diameter of 20 mm. The metric thread size is M6, and the total height of the element is 25 mm. The natural rubber used, with a hardness of 70 Shore A, provides good flexibility and effective vibration damping over a wide frequency range.

Application and benefits

Vibration isolators from the DVA.1 series find wide application in various industries, including:

• Mounting electric motors, pumps and fans – reducing vibrations transmitted to the device structure or foundation.
• Isolation of machine housings – minimizing noise and vibrations emitted to the environment.
• Mounting precision elements – protecting delicate components from damage caused by vibrations.
• Damping impacts and shocks – cushioning sudden dynamic loads.
• Isolation of electrical cabinets - reducing vibrations transmitted from the environment to sensitive components.

Selecting the appropriate vibration isolator is crucial for achieving optimal damping effects. It is necessary to consider parameters such as: vibration frequency, static load and the required degree of vibration reduction. If in doubt, it is worth consulting a specialist or using the technical data available from the manufacturer.

Construction and materials

The DVA.1-20-25-M6-18-70 vibration isolator consists of a threaded pin made of galvanized carbon steel and a damping body made of natural rubber (NR). The combination of these materials provides high mechanical strength and effective vibration damping. The rubber hardness of 70 Shore A guarantees good resistance to abrasion and aging, which translates to a long service life of the element. Galvanized steel protects against corrosion, allowing the vibration isolator to be used in various environmental conditions.
