Abstract
A sound isolating bearing has concentric inner and outer housings made of steel with a concentric shim between the inner and outer housings sandwiched by layers of a resilient elastomer. The longitudinal cross section of the shim is convex on both inside and outside surfaces with the same radius of curvature to allow cocking of the inner housing relative to the outer housing about a first point on the bearing axis midway between the ends and about a second pivot point outside the bearing in a plane midway between the bearing ends perpendicular to the bearing axis.
