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.

For the effective isolation of vibration and noise on different machines with rotating movements, like:

• compressors
• combustion engines
• generators
• converters
• pumps
• industrial / marine gen sets
• fans

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.
