Abstract
The disclosure provides bearing sleeves or bushings made of memory shape material, and processes for installing such bearing sleeves or bushings. In one process, inner and outer surfaces of a bearing sleeve, made of a memory shape material, may be compressed at least one first temperature. A bearing may be inserted in a cavity of the bearing sleeve, and the bearing sleeve may be disposed adjacent to a surface of a structure, while the bearing sleeve is at the at least one first temperature. The inner and outer surfaces of the bearing sleeve may be expanded, at least one second temperature, to abut against the bearing and the surface of the structure.
