Machinery Installation Vibration Isolation Noise Control

NOVIBRA TYPE RA

Novibra RA uses the rubber profile in shear and compression obtaining good vertical flexibility with the advantage of horizontal stability. For normal speeds of approx. 1500 rpm the RA type provides a degree of isolation of 75-85%. For even better isolation, the alternative RAEM or M can be chosen. Its unique construction and the latest production methods make Novibra type RA a high performance mounting having a number of advantages.

Advantages


 Rubber features are utilized effectively combining compression and shear.

• Tight tolerances on dynamic stiffness rate for accurate vibration calculations.

• Wide load rating options, 40-2100 kg.

• Corrosion protected to cope with arduous environments on land or marine applications (Fe/Zn 8C as per ISO 2081).

• Stronger base metal withstands high shock loads without deformation.

• Fitted as standard with a shock-proof device (up to 5 g) with resilient stop, making RA ideal for use on mobile or marine applications.

• Clear and durable product marking so that mountings can be identified even after several years in operation.

• Domed shape cover to protect against oil contamination.
