A numerical method is given for solving rolling contact problems with traction force and differential slip. The theoretical basis of differential slip is described in a manner such that the physical meanings of the problems can be understood directly. Based on the slipping velocity, the amount of wear was calculated. The following results were obtained. (1) The component of frictional pressure perpendicular to the rolling direction never vanishes, so the contacting bodies are microscopically slipping on the area neighboring the trailing edge, including the pure rolling line. Proceeding along the trailing edge, the sliding direction changes gradually from -90°to +90°. (2) The shape of the contact area of the upper body is slightly different from the one of the lower body because of the small difference in elastic deformation at the leading edge.
