Abstract
A self-lubricating journal bearing includes an arcuate bearing plate having a concave bearing surface. A plurality of lubricant plugs are positioned in apertures in the surface of said plate and are adapted to engage a rotating journal supported on said bearing surface for providing lubrication between said journal and said bearing plate. The lubricant plugs comprise an oil and polymer lubricating composition. The apertures and plugs are arranged to provide continuous lubrication over substantially the entire bearing surface as the journal rotates thereon, and coolant grooves are cut into the bearing surface of said bearing plate in a generally X-shaped pattern for channeling liquid coolant between the journal and the bearing plate.
