An improved bearing provided with either one or two or more of an oil groove, oil indentation, oil indent pattern and the like formed in the internal surface of a semi-circular cylindrical bearing or semi-circular bearing component. The sum of the lengths, measured on the internal surface, of the formed oil groove, oil indentation or the like appearing in any cross section of main loaded area in the axial direction being made to be 5- 50% of the width of the bearing enables a smooth swinging or rocking motion of the shaft by allowing an oil film or the like to always be formed on the main loaded area while preventing early fatigue failure. |
