Vibration isolator DVA.2-15-10-M4-10-70 Z050515

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

The DVA.2-15-10-M4-10-70 vibration isolator is an element designed to dampen vibrations and reduce noise generated by machines and equipment. Its construction, combining galvanized steel with natural rubber, provides effective insulation and extends the service life of the equipment. This is particularly important in applications where vibrations can affect work comfort, accuracy of operation, or operator safety.

This model is characterized by a combination of a threaded pin with a molded insert with a non-through threaded hole. This construction enables stable mounting and effective vibration damping in various configurations. The vibration isolator is used in mounting components of devices, such as motors, fans or pumps, as well as in isolating from external vibrations – e.g. when mounting electrical cabinets.

Construction and properties

The DVA.2-15-10-M4-10-70 vibration isolator is made of high-quality galvanized steel, which ensures corrosion resistance and durability. The damping element is made of natural rubber (NR) with a hardness of 70 degrees on the Shore A scale ±5. The hardness of the rubber affects the damping characteristics – higher hardness means greater stiffness and better handling of static loads, while lower hardness provides better damping of low-frequency vibrations.

This vibration isolator has a diameter of 15 mm and a height of 10 mm, which should be taken into account when selecting it for a specific mounting space. It has an external and internal metric M4 thread, which facilitates its integration with various structural elements. Rubber hardness at 70 Shore A provides optimal damping properties for many industrial applications.

Choosing the right rubber hardness is crucial for effective vibration damping and ensuring optimal performance of the insulation system. It is worth remembering that rubber is characterized by high internal damping and the ability to absorb sound, which translates into quieter operation of machines and equipment. In addition, rubber is a corrosion-resistant material and is characterized by high fatigue strength over a wide temperature range (-40°C to +80°C).
