Hourglass bobbin mounts (F-F) CF are devices designed to effectively reduce vibrations and mechanical oscillations in a wide range of industrial and mechanical applications. Their hourglass shape, characterised by a central bottleneck, provides excellent vibration absorption capacity in both axial and radial directions.
Made from high-quality materials, such as natural rubber (NR) or synthetic compounds such as NR/SBR, and equipped with metal inserts with internal threads on both sides, these dampers guarantee simple and safe assembly. The female-female connection allows for easy integration into systems that require screw or bolt fastenings on both ends, offering a versatile solution for vibration control.
The advantages of female-female hourglass dampers lie in their ability to combine flexibility and strength. The hourglass shape allows an even distribution of forces, reducing stress on mechanical components and improving the overall stability of the equipment.
The rubber used, with a typical hardness of 50-60 Shore A, offers excellent damping capacity, while the galvanised metal inserts guarantee corrosion resistance and long life, even in harsh environments. In addition, a choice of rubber compounds and thread sizes allows the product to be tailored to specific needs, making it ideal for applications that require a balance between rigidity and flexibility.
These dampers find application in many sectors, such as the automotive industry, agricultural machinery, ventilation systems and heavy equipment. They are particularly useful in configurations requiring support of dynamic loads, such as motors, pumps, compressors or machinery subject to oscillatory movements. The female-female connection makes them ideal for installations where two elements need to be bolted together, ensuring a stable attachment without compromising damping effectiveness. In sensitive environments, such as the food or medical industry, FDA-compliant materials can be used, ensuring safety and resistance to extreme temperatures (-30°C to +200°C).
The use of female-female hourglass dampers helps to improve equipment life by reducing wear and tear caused by vibration and minimising operating noise, a crucial aspect in working or residential environments. They also prevent structural damage due to repeated mechanical stress, reducing maintenance costs. These dampers provide a practical and efficient solution for optimising the performance of machinery, ensuring reliability and comfort in environments subject to high dynamic loads.
