摘要：

A bearing assembly including a load-carrying shaft, an electrically non-conductive sleeve fitted over the shaft, and a surrogate shaft surface made from a corrosion resistant metal surrounding the non-conductive sleeve. The bearing assembly electrically isolates the load-carrying shaft from an underwater structure. This isolation prevents carbonates from building up in the void space between the metallic surrogate shaft surface and a bearing. A rotor or slider subassembly may be included in the bearing assembly. A bearing may be affixed as part of the rotor or slider assembly located between the slider and the surrogate shaft surface.
