A spherical plain bearing has an outer ring having a concave bearing surface, and an inner ring having a convex bearing surface and a shaft-engaging surface. The inner ring is disposed within the outer ring with the concave surface engaging the convex surface. The inner ring has a lubrication groove on the convex surface and a lubrication aperture that extends from the groove to the shaft-engaging surface. A shaft is mounted in the inner ring. The shaft has a lubrication aperture that communicates with the inner ring lubrication aperture. Lubricant can be injected into the shaft lubrication aperture to flow lubricant into the bearing load zone via the inner ring lubrication aperture. In another aspect, a kingpin linkage assembly includes an axle yoke, a steering knuckle, two king pins pivotally interconnecting the axle yoke and the steering knuckle, and two bearings as described herein for engaging the kingpins.
