<P>PROBLEM TO BE SOLVED: To provide a sliding bearing for heavy load suitable for sliding at a high surface pressure in a swinging state, having durability, and formed to be easily manufactured. <P>SOLUTION: A bearing alloy is formed of a ferrous sintered alloy of hardened structure, and comprises a tilted groove within a tilt angle of 10 to 40° relative to a direction orthogonal to a sliding direction. The tilt groove is within the range of 2 to 8 mm in width, and the area thereof on the inner peripheral surface is within a range not exceeding 50%. A virtual line orthogonal to the sliding direction crosses both the bearing surface and the tilt groove even at any position on the inner peripheral surface of the bearing. When the bearing alloy is used, a lubricant is filled in the tilt groove. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
