The camshaft journal bearings including a pair of end camshaft journal bearings positioned adjacent the ends of the camshaft body, respectively. At least one inner camshaft journal bearing positioned intermediate the pair of end camshaft journal bearings, the each end camshaft journal bearing having a lubricant transfer device formed in it for receiving lubricant from an external supply and for transferring lubricant into the hollow interior; and at least one radial hole (11a-e) formed in the camshaft body for each the inner camshaft journal bearing for providing lubricant from the hollow interior to the inner camshaft journal bearing.
