Abstract
A bearing for carrying compressive radial loads comprising alternating bonded layers of a resilient material of a uniform modulus of elasticity and layers of a non-extensible material, all generally concentrically formed about a common center axis. The fatigue life of the bearing under torsional and compressive loads is enhanced by progressively decreasing both the length and thickness of each layer of resilient material with increasing radii, so that a substantially equal strain is carried across each layer of resilient material in response to each torsional load and the shape factor of each of the layers of resilient material remains substantially constant or increases with increasing radii.
