The paper describes a nano-bearing that is composed of carbon nanotubes analyzed by molecular dynamics simulation. To describe multiwall carbon nanotubes, Tersoff potential is applied for atoms in a basal plane of tubes and the Morse potential is for interlayer tubes, whose parameters are newly developed based on the equilibrium interlayer distance, the interlayer cohesive energy and the Young's modulus in the interlayer direction of graphite. The research shows the excellent possibility and properties of the nano-bearing composed of zigzag tubes It works on the wide range of temperature from 0K to 3000K, with high rotation speed and accuracy and in an ultra-high vacuum without any lubricant.
