The composite journal bearings which have outer layer with high strength and inner layer with high wear resistance can be used as bearing materials in the industrial high-power machine. The complex layer bearing prepared by unification forming of two different mixed powders with Fe-Cu-C in outer layer and Fe-Cu-C-Ni-Cr in inner layer, and then it was sintered for 9.0ks at 1403K. The sliding property to hardening steel shaft of the complex layer bearing was invested by swing-type sliding machine. The wear properties in this bearing were examined and also estimated on the connection with the wear property of rotary shaft. Wear loss volume of complex-layer bearing is extremely lower than the single-layer bearing. However, There is a slightly difference the wear-loss volume of rotary shaft by the swing-type sliding for the complex-layer bearing and single-layer bearing.
