ABSTRACT:
A laminated bearing comprises a plurality of alternating and bonded together layers of elastomeric material and substantially nonextensible material. Each of the layers is a frustroconically shaped annulus that has a pair of frustroconically shaped side surfaces and is concentrically disposed about a common axis extending lengthwise of the bearing. The side surfaces of adjacent layers are bonded to each other such that the larger diameter end of each layer is disposed adjacent to the larger diameter end of another layer. Together, the larger diameter ends of the layers define an annular surface of the bearing. The annular surface formed by the ends of the layers defines, in radial section, an angle with respect to a line which lies normal to the side surfaces of the layers. The direction of the angle or inclination, with respect to the normal line, is toward the smaller diameter ends of the layers with increasing distance along the normal line away from the common axis. Preferably, the angle is about 9.degree..
