Vibration isolator DVA.2-10-15-SST-M4-10-55 Z038197

Vibration Isolators – Reduction of Vibrations and Noise

Vibration isolators from the DVA.2 series are elements designed to effectively dampen vibrations and reduce noise in machines and equipment. They are used wherever it is necessary to isolate vibration-sensitive elements or limit their transmission to the environment. The construction based on a combination of natural rubber and stainless steel (in the SST version) ensures durability and reliability in various working conditions.

Construction and Materials

The DVA.2 vibration isolator consists of a threaded pin and a molded insert with a non-through threaded hole. The standard version has elements made of galvanized steel, while the SST version is characterized by the use of AISI 304 stainless steel, which increases corrosion resistance and allows for use in environments requiring high hygiene or exposure to aggressive substances. The damping body is made of natural rubber NR with a hardness of 55 Shore A (other hardnesses are also available). The hardness of the rubber affects the damping characteristics – soft rubber better absorbs low-frequency vibrations, and hard rubber – high-frequency vibrations.

Applications and Benefits

DVA.2 vibration isolators find wide application in many industries, including:

• Mechanical Engineering: Damping vibrations of engines, pumps, fans and other mechanical devices.
• Food Industry: Isolation of production machines from the building structure, minimizing the risk of vibration transmission to products.
• Construction: Reduction of noise and vibrations generated by HVAC equipment (heating, ventilation, and air conditioning).
• Electronics: Protection of precise electronic devices from damage caused by vibrations.
• Automation: Damping vibrations of industrial robots and other automation equipment.

Using DVA.2 vibration isolators translates into a number of benefits:

• Noise Reduction: Reducing the noise level generated by machines and equipment improves working comfort and meets acoustic safety standards.
• Protection Against Damage: Damping vibrations reduces the risk of mechanical damage to machine and equipment components, extending their service life.
• Improved Accuracy: Isolation from vibrations increases the accuracy of measuring and control devices.
• Increased Work Comfort: Reducing vibrations transmitted to the operator improves work comfort and reduces the risk of occupational diseases related to vibration exposure.
• Structure Protection: Reducing the load on the building structure caused by vibrations of machines and equipment.

This specific model – DVA.2-10-15-SST-M4-10-55 – is characterized by a diameter of 10 mm, a height of 15 mm and an M4 thread. The construction of AISI 304 stainless steel and a rubber hardness of 55 Shore A ensure high corrosion resistance and optimal damping properties for a wide range of applications.
