– Vertical and lateral own frequencies under loads of 5 to 8 Hz.
– Maximum travel around the position under load: vertical: ± 50 mm lateral : ± 45 mm
Flexible mountings for low loads MN 50
The permitted deflection (40 to 50 mm) of the suspended mass in relation to the mounting base limits reaction under shock.No efficient vibration protection is offerred during shock.

Flexible mountings for low loads MN08 – MN09
The main role of these mountings is to isolate vibration.
The main role of these mountings is to isolate vibration. A snubber system limits the movement of the suspended mass (10 mm), however the loads developed in this case, are high.
A wide load range from 5 to 320 N depending upon the application.

Laminated bearings
Are used to absorb very high axial loads of up to 150 tons.
Conical (fig. 1) or spherical (fig. 2) units are used to absorb very high axial loads of up to150 tons.
Angular movement around an axis (Oz in the case of the conical bearing) or a centre of rotation (O in the case of the spherical bearing) are in the order of ± 10°.

Strafluid Hydraulic mountings
A hydraulic suspension can at the same time provide a low frequency damping function.
The progress in motor vehicle design and increased demand for comfort both in terms of vibration and sound-proofing has resulted inincreasingly demanding specifications for suspension systems.
PAULSTRA hydraulic mountings use an elastomer support device combined with an hydraulic system. The hydraulic system acts differentially and specifically in relation to the frequency range and the type of vibrational excitation incurred.
These mountings, due to a total integration of all components, are still compatible with standard sizes and are as easy to fit as conventional mountings.
