Abstract
A laminated bushing is formed from a metal sheet having resilient material disposed on one side by spirally winding the metal sheet about a longitudinal axis to form a spirally shaped cavity. The resilient material is disposed within the spirally shaped cavity and the metal sheet forming the spiral shaped cavity either mechanically compresses the resilient material disposed within the cavities, or the resilient material is vulcanized once the laminated bushing is formed. The spirally wound laminated bushing includes inner and outer sleeves concentric about the longitudinal axis that are movable relative to one another in direct proportion to the material deformation properties of the resilient material.
