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

Vibration isolator DVA.4-50-20-M10-28-55 is an element dedicated to damping vibrations and reducing noise generated by operating machines and equipment. Its use translates to improved work comfort, increased safety, and extended equipment life. This is particularly important in applications where vibrations can negatively affect the accuracy of operation or cause damage to structural elements.

This specific model, characterized by a cylindrical design, is made of galvanized steel, which ensures corrosion resistance and durability even in harsh environmental conditions. It has an external M10 thread for mounting and a diameter of 50 mm, and its height is 20 mm. It utilizes the damping properties of rubber with a hardness of 55 on the Shore scale, which allows for effective absorption of vibration energy.

Design and application

Vibration isolators from the DVA.4 series are widely used as shock-absorbing elements (bumpers) and for mounting devices with a smaller mass – from a few to several hundred kilograms. They are ideal for mounting components such as motors, fans, or pumps. Thanks to their design, they effectively isolate vibrations transmitted from the device to the substrate or vice versa – protecting sensitive elements from external vibrations.

Selecting the right vibration isolator is crucial for achieving optimal results. It is necessary to consider parameters such as vibration frequency, element load, and the required degree of damping. It is worth remembering that rubber is characterized by high internal damping and good shape elasticity, making it an effective material for vibration isolation. Choosing rubber with the appropriate hardness (55 Shore'a in this case) allows you to adapt the damping properties to specific application requirements.
