Vibration isolator DVA.1-8-8-SST-M3-6-55 Z038192

Vibration Isolators – Reduction of Vibrations and Noise

Vibration isolators from the DVA.1 series are elements designed to dampen vibrations and reduce noise in machines and equipment. Their use translates to improved working comfort, increased equipment durability, and reduced negative impact of vibrations on the environment. A construction based on a combination of natural rubber and stainless steel (in the SST version) provides effective isolation in a wide range of applications.

Construction and Materials

The DVA.1 vibration isolator is characterized by a cylindrical structure with a threaded pin. The pin is made of galvanized steel as standard, and in the SST version – of stainless steel AISI 304, which ensures corrosion resistance and the possibility of use in harsh environmental conditions. The damping body is made of natural rubber NR with a hardness of 55 Shore A, providing optimal damping properties for many applications. Other rubber hardnesses are also available, but the 55 Shore A version is offered as standard.

Applications and Benefits

DVA.1 vibration isolators find wide application in various industries, including:

• Mounting of motors, pumps and fans: Reduction of vibrations transmitted to the device or foundation structure.
• Isolation of machine housings: Reducing noise generated by operating machines.
• Mounting of electrical cabinets: Reducing the impact of vibrations on sensitive electronic components.
• Automotive industry: Damping vibrations in suspension and drive components (although this particular model is not typical for this application).
• Precision instruments: Ensuring stability and measurement accuracy by eliminating the influence of vibrations.

Using DVA.1 vibration isolators brings the following benefits:

• Noise reduction: Improving working conditions and acoustic comfort.
• Increased equipment durability: Protecting components from damage caused by vibrations.
• Improved safety: Reducing the risk of failure due to resonance or material fatigue.
• Environmental protection: Reducing noise emissions to the environment.
• Corrosion resistance (SST version): Possibility of use in aggressive industrial environments.

Technical Parameters and Selection of the Appropriate Model

The selection of the appropriate vibration isolator should take into account the static load, vibration frequency and the required degree of damping. Model DVA.1-8-8-SST-M3-6-55 has the following parameters:

• Diameter: 8 mm
• Metric thread size: M3
• Rubber hardness (Shore A): 55
• Connection 1 & 2: External thread
• Height: 8 mm

Please note that a wide range of DVA.1 models with different dimensions, rubber hardnesses and materials are available, allowing you to choose the optimal solution for a specific application. Detailed technical data for individual models can be found in the manufacturer's catalogs or at distributors such as Onninen.
