Abstract
A main-load side bearing metal piece on which a heavy load is imposed is coated on an inner surface thereof with a thin overlay having a uniform thickness. Meanwhile, a non-load side bearing metal piece is coated on an inner surface thereof with an overlay having a uniform thickness greater than that of the overlay formed on the inner surface of the main-load side bearing metal piece. With this construction, the bearing metal piece shows excellent load carrying capacity and fatigue resistance because the overlay formed on the inner surface thereof is thin, while the non-load side bearing metal piece shows excellent foreign matter embeddability and conformability because the overlay formed on the inner surface thereof is thick. Moreover, since there are formed the overlays each having a uniform thickness in respective inner surfaces of each of the bearing metal pieces, and therefore it is possible to reduce the manufacturing cost.
