Abstract
Apparatus and methods provide for a bushing that compensates for thermal expansion and contraction to maintain a preload on a corresponding structure at various operating temperatures. According to embodiments described herein, a bushing may include two bushing components coupled to a load compensation sleeve between the two bushing components. The load compensation sleeve may have a coefficient of thermal expansion (CTE) greater than the two bushing components and the corresponding abutting structure. The configuration of the bushing components and load compensation sleeve, along with the corresponding CTE characteristics, maintains the preload imposed by the two bushing components on the structure throughout operations at various temperatures.
