description PROBLEM TO BE SOLVED: To provide an aluminum based bearing alloy with excellent fatigue resistance, non-seizuring property and wear resistance and enhance its rollability by preventing an intermetallic compound produced by added elements from becoming acicular. SOLUTION: The aluminum based bearing alloy comprises Sn of 3.5 to 20 wt.%, Si of 0.5 to 4.5 wt.%, Mn of 0.01 to 2 wt.%, and V and/or Mo of 0.01 to 2 wt.%, with the rest being substantially Al. Sn, Si, Mn and the like are added to Al to enhance the fatigue resistance, non-seizuring property and wear resistance of the bearing alloy. The addition of various elements to Al results in a higher probability of a brittle acicular intermetallic compound forming within a matrix, while the addition of V and/or Mo prevents the intermetallic compound from becoming acicular but instead forms it into solid. The intermetallic compound is solidified to maintain the toughness of the bearing alloy and achieve high strength.
