  • Bearing assembly and method and lubrication grease
    Patent number: 6677283
    Abstract: Disclosed is a bearing assembly that includes a bearing insert that engages a bearing housing at an interface. In accordance with the invention, the interface is lubricated with a lubricant that provides sufficient lubrication such that the breaking housing torque required to initiate relative movement of the outer portion and housing is no greater than 130% of the moving housing torque required to maintain relative movement of the outer portion and housing. The lubricant preferably is a fatty acid, such as stearic acid or palmitic acid. In accordance with highly preferred embodiments of the invention, the lubricant comprises a grease composed of a base lubricating oil that is thickened with a fatty acid that is substantially uniformly dispersed therein.
