BA™ & Double U Shear™
Features
Novibra® type BA and Metalastik® type Double U-Shear
mountings utilise bonded rubber in shear to permit
relatively high deflections. Provides excellent isolation of low
frequencies. (Type BA20/2 is a half section suitable for very
light loads). On rotatingequipmentapplications the soft axis
should be at right angles to the shaft. On mobile
applications the stiff axis should be aligned in the direction
of travel.
