Abstract

A rolling-element bearing includes a first rolling-element bearing ring configured to be mechanically connectable to a stationary component, a second rolling-element bearing ring configured to be mechanically connectable to a rotating component and at least one porous body disposed between the first rolling-element bearing ring and the second rolling-element bearing ring and configured to hold a lubricant. The at least one porous body is mechanically coupled to the second rolling-element bearing ring and configured such that during rotation of the second rolling-element bearing ring the at least one porous body substantially rotates with the second rolling-element bearing ring, and, due to this rotation, releases an amount of the lubricant. The at least one porous body is further configured to absorb at least a portion of the released amount lubricant when the second rolling-element bearing ring is stationary.
