Form factorThe form factor is a geometric measure for the shape of an elastomeric bearing defined as the ratio of the loaded area and the area of sum of the perimeter surfaces.
definition: form factor=
for a rectangular shape: q=
The form factor has an influence on the deflection and the static load limit respectively.
Elastic Sylodyn-bearings are considered asfull surface bearing: form factor > 6strip bearing: form factor between 2 and 6point bearing: form factor < 2
Influence of the form factor on the deflection at the static load limit for a homogeneous materialreference value: form factor q=3
Influence of the form factor on the static load limit for a homogeneous materialreference value: form factor q=3
