Abstract
An aspect of the present disclosure relates to a fluid bearing and a method of adjusting the load carrying capacity of a fluid bearing. The fluid bearing may include a bore defined in the fluid bearing and a rotatable bearing including a rotatable bearing surface. Lubricating fluid in the bore may be contacted with at least a portion of the rotatable bearing surface, wherein an effective bearing surface area is provided where the lubricating fluid contacts the rotatable bearing surface. The effective bearing surface area may be altered by either increasing or reducing the area of the rotatable bearing surface which is contacted by the lubricating fluid.
