1. the production method of a sliding bearing, this sliding bearing has:

  • parent, it is cylindric, is formed by metal;

    Sliding layer, the surface that it is formed on this parent has the bearing surface that slides with shaft component,Said parent has the surface of contact that rotates or slide with mating component at outer circumferential face,Said sliding layer forms to both ends of the surface from the inner peripheral surface of said parent;

    The bearing surface of said sliding layer that is formed at the inner peripheral surface of said parent is the radial bearing surface that supports the radial load of said shaft component;

    The bearing surface of said sliding layer that is formed at the both ends of the surface of said parent is the axial axis bearing surface that supports the thrust load of said shaft component respectively;

    The production method of said sliding bearing is characterised in that, comprising;

    By Fe is that the sintering metal material forms said parent, and the surperficial percent opening that makes inner peripheral surface and the both ends of the surface of said parent is 20%~

    50% operation;

    Make the operation of porous silica immersion lubrication agent;

    Allotment forms the operation of glide material composition as resin, the oiling agent of substrate material, the porous silica that in above-mentioned operation, has flooded oiling agent and enhancing material;

    Thereby the glide material composition that will in above-mentioned operation, form embeds and forms in the inner peripheral surface of said parent and the operation that both ends of the surface form said sliding layer.
