LORD elastomeric torsion springs provide office chairs with easy positioning and smooth, quiet motion. Our rubber-to-metal, fully bonded elastomeric springs are smaller than conventional metal coil springs and allow for a more attractive and compact chair design. Elastomer formulations, which provide gradual stiffening at high deflections, are easily adjusted to accommodate specific stiffness and damping requirements. Elastomeric torsion springs are available with an attachment arm for easy assembly or with the part in place in the chair control mechanism.
