Abstract
A link apparatus includes a tubular member that retains 90% of ultimate tensile strength at a temperature of up to 329.44° Celsius (625° Fahrenheit). Two conical adapters are joined to ends of the tubular member. One threaded shank of a rod end is threaded into a right hand threaded base of one conical adapter, and a threaded shank of another rod end is threaded into a left hand threaded base of the other conical adapter. Each rod end has a bearing assembly disposed therein including an outer race, a ball disposed therein, and a low-friction liner disposed between the outer race and ball for mitigating moment loading on the tubular member. The cross-sectional area of the tubular member is at least as great as the cross sectional area of the rod ends. The tubular member is tensionable by rotation relative to the rod ends.
