Novibra® type SAWNovibra® elements type SAW are heavy duty mountings for static and shock loads in compression. Provides high isolation in the horizontal shear direction.
Typical fields of application are:• Crushers • Vibratory rollers• Edge runners • Screens• Mills • Other very heavy • Hoppers and feeders machines and • Grinders equipment
FeaturesNovibra® type SAW mountings consist of a cylindrical shaped rubber section with integrally bonded interleaf metal plates bonded to two square heavy duty outer metal fixing plates. Designed for large compressive forces with minimum deformation, while providing low shear stiff-ness rates.
The combination of a stable low installation height, high compressive strength and low shear stiffness makes Novibra® type SAW a versatile high performance antivi-bration mounting. Ease of installation due to 4 clearance holes in each fixing plate.
By connecting 2 SAW-elements in series, i.e. one on top of the other, an increased isolation efficiency is achieved in both shear and compression planes. Where larger de-flections are required in the vertical plane, Novibra® type SAW mountings are mounted at a calculated angle config-uration to provide the optimum spring rate.
Shear loads only. See separate diagram for shear load.

FeaturesRectangular SAW mountings are also known as ’Sand-wich’ mountings because they feature a rubber section sandwiched between plates of metal. This arrangement allows a large difference between the compression and shear stiffnesses, thus providing the potential to ’tune’ a mounting system by rotating the mountings. These mountings are commonly installed in a ’Vee’ formation to utilise this feature.
The Rectangular SAW Mountings has the following fea-tures:• Available with plate or stud fixings.• Can be loaded in compression or shear, or a combination
of both, for example in a ’Vee’ arrangement.• Can be manufactured with or without interleaves to
change the ratio of shear to compression stiffness.

FeaturesThe metal interleaf incorporated (17-1392) in the design provides a higher compression to shear stiffness ratio, thereby increasing the load capacity in the compression or combined compression and shear modes.
The 17-1780 engine mounting features a void in the rub-ber section to allow the use of a central snubber device.
