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

Vibration isolator DVA.2-20-20-M6-18-70 is an element designed to dampen vibrations and reduce noise generated by operating machines and equipment. Its construction, combining galvanized steel with natural rubber, provides effective insulation, protecting both the equipment itself and the surroundings. Installing this type of vibration isolator translates into extending the service life of machines by reducing dynamic loads on structural elements.

Construction and application

This particular model is characterized by a threaded pin and a molded insert with a non-through threaded hole, which facilitates assembly and ensures a stable connection. Made of galvanized steel, it is resistant to corrosion, which increases its durability even in harsh environmental conditions. The DVA.2 vibration isolator finds application in many industries – from the machinery industry, through automotive, to construction. It is used for mounting engines, pumps, fans and other elements generating vibrations.

• Construction: combination of a steel pin and an insert with a rubber damping element.
• Material: galvanized steel provides corrosion resistance and mechanical strength.
• Rubber hardness: 70 Shore A – provides optimal vibration damping while maintaining adequate stiffness.
• Thread: M6 facilitates mounting in standard threaded holes.
• Diameter: 20 mm – dimension important when selecting for specific applications.
• Height: 20 mm - compact dimensions allow for use in limited space.

Selecting the appropriate rubber hardness (70 Shore A in this case) is crucial for effectively damping vibrations of a specific frequency and amplitude. Too soft rubber can cause excessive deflection, and too hard rubber – insufficient damping. These types of vibration isolators allow you to isolate the device from the substrate or vice versa - isolate the substrate from vibrations generated by the device (active and passive vibration isolation).
