An improved journal bearing includes a first groove, in the direction of journal rotation, formed in the inner surface of the journal bearing. The first groove extends axially along the length of the bearing and has opposed, open groove ends. A second groove, in the direction of journal rotation, is formed in the inner surface of the journal bearing. The second groove extends axially along the length of the bearing and has opposed, closed ends. An orifice is provided for supplying a lubricant to the inner surface of the journal bearing. The lubricant supply orifice is disposed substantially centrally along the bearing length and intermediate the first and second grooves.
