PROBLEM TO BE SOLVED: To prevent the damage of a bearing when an unexpected impact load and a large load are applied (at high-loading) by enlarging a bearing capacity and reducing plane pressure when the unexpected impact load and the large load are applied (at high-loading).SOLUTION: A rolling bearing is a radial needle bearing which is arranged between a rotating shaft 1 and an outer ring 2 which can relatively rotate with respect to each other, and arranged in a double-row. A rolling body 8 which is assembled in a center row is larger in diameter than rolling bodies 14, 20 which are assembled at left and right rows, and the rolling bodies are assembled with positive clearances a, b and b.SELECTED DRAWING: Figure 1 |
