Abstract：To solve the problem that cylindrical roller bearings were easily worn under heavy load conditions, a doublelayer metal composite inner ring cylindrical roller bearing was designed. Taking the contact between the composite inner ring and the roller as example, the maximum contact stress of a single roller and the bearing inner ring was obtained based on Hertz contact theory and Boussinesq theory. The mechanical model of combined layer composite material was used to calculate the doublelayer metal composite equivalent elastic modulus of inner ring. The contact model between inner ring and single roller was established, and the finite element simulation method was used to explore contact stress and elastic deformation for different material thickness. Through contact friction test, the contact widths were verified with different material thicknesses of composite inner ring. The results show that the contact deformation of doublelayer metal composite between inner ring bearing roller and inner ring is increased with reduced contact stress, which is helpful to reduce the wear of cylindrical roller bearing.
