Product description


GN 451.2 vibration isolation mounts, also known as vibration mounts, anti-vibration mounts, vibration bobbins or rubber bumpers, are suitable for the elastic mounting of machine units such as motors, compressors and pumps.

These rubber mounts are simple and economical construction elements. Their resilience and their broad range of different sizes and dimensions allow these mounts to be used in many applications that require vibration isolation.
