  • (1) The axial load capacities correspond to maxiumum displacements based on design limits of 250% rubber shear strain or 2/3 the isolator diameter. An isolators actual displace-ment and load capacity are dependent on the rubber modulus and number of rubber layers.

    (2) Rubber Shear Moduli (G) are available from 55 psi to 100 psi.

    (3) For analytical bilinear modeling of the Elastic Stiffness use Ke=10*Kd.
