Abstract
A method includes providing a bearing housing configured to house a bearing, the bearing housing enclosing a free volume for receiving a lubricant and including a shaft in a shaft opening, filling the free volume with the lubricant, providing an exclusion seal between the shaft opening and the shaft, the exclusion seal being repeatably and non-destructively shiftable from a sealing state and a release state, the exclusion seal being shiftable from the sealing state to the release state by increasing a pressure in the bearing housing to above a first level and being shiftable from the release state to the sealing state by decreasing the pressure to below the first level; and continuously maintaining a film of the lubricant between the exclusion seal and the shaft by repeatedly causing the pressure of the lubricant in the free volume to rise above and fall below the first level.
