  • Link and bearing for rotary coupling
    Patent number: 5186686
    Abstract: A link for use in a link-type rotary coupling. The link has an elastomeric bearing which incorporates a pair of cavities that provide discontinuities for preventing the transfer of tensile stresses in the elastomeric layers when the link is tensioned axially while permitting the elastomeric layers to accept compressive stresses when the link is compressed axially. The resulting link is durable.
