Abstract
A flexible tension bearing connector includes a cylinder having a base portion supporting a central rigid spacer therein having an outer spherical surface facing away from the base portion and a center of curvature at the axis of the cylinder. A nipple has an internal spherically shaped surface contiguous to the spacer in a mating relation. An elastomeric bearing has an end inner ring which has a cylindrical center bore to receive the nipple and an end outer ring captured inside the cylinder. An intermediate elastomeric section has spherical geometry centered at the center of curvature of the spacer. The bearing encircles the nipple with annular planar bearing surface facing away from the spaces in a plane normal to the cylinder axis. A stop on the nipple contacts the annular planar bearing surface to transfer through the bearing to the cylinder any forces which would urge the bearing away from the spacer.
