Abstract
A rolling-element bearing for a device lubricated with a fluid includes first and second bearing rings defining an interior therebetween in which rolling elements support the first ring for rotation relative to the second ring. A pumping device is located at the interior for pumping the fluid into and/or out of the interior when an element of the rolling-element bearing rotates and the rolling-element bearing is at least partially submerged in the fluid. The pumping device may be a ring having vanes that is attached to the first bearing ring or to a cage of the bearing.
