Abstract
There are provided a spherical bearing and a method for manufacturing the same, in which both of a ball bearing section and a ball section made of metal can make light and smooth swinging and rotary motions for a long period of time without biased wear and seize-up of those members even if the solid bodies of them can contact with each other due to a discontinuous oil film under a heavy load. A resin liner that contacts the ball section of the inner member in a sliding relationship is embedded in the ball bearing section, and a resin sliding contact surface provided by the resin liner and the metal sliding surface are adjacent to each other without any gap to form a sliding contact surface at the bearing section.
