Features:
Novibra RA and EF 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 Novibra RA and EF type provides a degree of isolation of 75% - 85%. For better isolation, the alternative Novibra RAEM or Novibra M can be chosen.
It's unique constructino and the latest production methods make Novibra type RA and EF a high performance mounting having a number of advantages:
- Rubber features are ustilized effectively combining compression and shear
- Wide Load rating options, 40-2100 kg
- Corrosion protected to cope with arduous environments on land or marine applications (Fe/Zn8C as per ISO 2081)
- Fitted as standard with an integral fail-safe design device with resilient stop, making Novibra RA and EF ideal for use in mobile or marine applications. The Novibra RA/EF mounts can accommodate occasional shock loads to 5 g reference to the weight in hardness 60 degree IRH. The mount will withstand shock loads up to 2 g without plastic deformation.
- 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.
