Glass-fibre reinforced polyamide based (PA) technopolymer, black colour, matte finish.
Polyurethane-based rubber (PUR), natural colour, hardness 50 Shore A.
Glass-fibre reinforced polyamide based (PA) SUPER-technopolymer, with hexagonal socket and regulation hexagon.
Thanks to the property of the SUPER-technopolymer stem, high rigidity and mechanical resistance are obtained in addition to natural resistance to corrosion.
Have been designed to damp vibrations, shocks and noises produced by moving bodies or non-balanced vibrating masses of equipment and machines which can cause:
The levelling feet are supplied unassembled to make carriage and storage easier. The components (base and stem) are supplied in separate packing: less volume taken and better protection from scratches and dirt.
To order bases and stems separately, see:
The maximum static load value shown in the table indicates the static load for a specific load of 0.4 N/mm2 to which the damping element can be subjected in order to have optimal vibration absorption.
The table shows also the values (l2) of elastic deformation with a load of max 0.6 N/mmÂ² in case of a dynamic load.
The effectiveness of the damping depends on the ratio between the disturbance frequency of the machine and the natural frequency of the damping foot.
The natural frequency of the base depends on the material, the geometry, and the specific load [N/mm2] to which it is subjected.
The specific load is obtained by dividing the applied load by the support area of the damping element.
Once the specific load is known, the natural frequency of the foot can be obtained from the graph in figure 1.
The damping starts when the ratio between the disturbance frequency of the machine and the natural frequency of the damping foot is greater than âˆš2. The greater the difference between the interference frequency of the machine and the natural frequency of the foot, the greater the damping (see figure 2).
