ABSTRACT:
A rotatable shaft has an extended vertical length radially supported by a lubricant impervious bearing. Lubricant is transferred upward to the shaft bearing surface by capillary attraction from an absorbent washer surrounding the bottom of the bearing. A wick conveys the lubricant to the washer from a lower lubricant reservoir. A seepage barrier is further included having a wick extending across the open end of an upright support column and against the shaft at the outer end. The wick returns any lubricant discharged from the end of the support column to an absorbent retainer.
