Abstract
A frusto-conical laminated elastomeric bearing is provided wherein at least some of the layers are graded in composition so that they have a first relatively high modulus of elasticity at the inner circumference, and a second relatively low modulus of elasticity at the outer circumference, with the grading being arranged so as to provide an optimum balance of strain distribution and spring rates consistent with bearing lifetime and reduced-torque considerations.
