Hourglass bobbin mounts (M-F) CM are designed to effectively reduce vibrations and mechanical oscillations in machinery and equipment of various types. Their characteristic hourglass shape, with a central bottleneck, allows them to absorb vibrations in both axial and radial directions, ensuring effective protection of mechanical components.
Made of natural rubber (NR) or synthetic compounds such as NR/SBR, these dampers feature a metal insert with an internal thread on one side (female) and a threaded stud on the other (male). This configuration facilitates mounting in systems that require mixed fixing, offering versatility and stability for applications that must handle dynamic loads.
The advantages of male-female hourglass dampers lie in their ability to combine simple installation with high damping efficiency. The hourglass shape ensures an even distribution of forces, reducing stress on components and improving equipment longevity.
The rubber, with a typical hardness of 50-60 Shore A, provides excellent vibration absorption capacity, while the galvanised metal inserts offer corrosion resistance, making them suitable for aggressive environments.
The male-female connection allows easy integration into complex systems, with customisation options for thread sizes and rubber compounds, adapting to different operating requirements.
These dampers find application in industries such as manufacturing, automotive, construction and agricultural equipment. They are ideal for machinery such as motors, pumps, fans and compressors, where vibration must be reduced to prevent wear and improve operational stability. The male-female connection is particularly useful in configurations that require a direct attachment on one side and a threaded connection on the other, such as in heavy machinery mounts or suspension systems. In sensitive environments, such as the food or pharmaceutical industry, FDA-compliant materials can be used, ensuring hygiene and resistance to temperatures between -30°C and +200°C.
The use of male-female hourglass dampers helps to extend the life of equipment by reducing wear caused by vibration and minimising noise, an important factor in working or residential environments. They also prevent structural damage due to repeated mechanical stress, reducing maintenance and repair costs. These dampers provide a practical and cost-effective solution for optimising the performance of machinery, ensuring reliability and comfort in environments subject to intense dynamic loads.
