Novibra type M - WILREP

1 M. Features Novibra type M is specifically designed to give large de- flection at low loads. Although the mount design allows high deflection, the mountings are compact in weight and easy to install. Its unique construction and the latest production methods make Novibra type M a high performance antivibration mounting having a number of advantages: Tight tolerances on dynamic stiffness rate for accurate vibration calculations. Wide load rating options, 2500 kg. Corrosion protected to cope with arduous environ- Novibra type M ments on land or marine applications (Fe/Zn8C2 as Type M is ideal for applications involving isolation of low per ISO 2081). frequency vibrations in all planes. Also suitable for shock Clear and durable product marking so that mountings attenuation due to the designed ability to offer large de- can be identified even after several years in operation.
