PROBLEM TO BE SOLVED: To provide a half-split bearing in which abrasion resistance is improved and an oil film is surely formed under boundary lubrication where it is difficult to form the oil film.SOLUTION: A half-split bearing 1 is formed arcuate along a direction where an object to be slid swings. The half-split bearing 1 comprises: a porous layer 4 formed from a Cu-Sn based alloy on a surface of a metal substrate 3; and a sliding layer 2 covering the porous layer 4 with a resin material 5 containing at least polytetrafluoroethylene and carbon fibers. On a surface of the sliding layer 2 where the object to be slid is supported so as to be slid, an oil film is formed by retaining oil, and an uneven surface 6 is formed with a height enough to retain the oil capable of forming the oil film, against abrasion caused by sliding the object to be slid. |
