For precision Miniature Ballscrew, PMI has reduced the Diameter of ballnut and used the special circulation system, to satisfy more stability and high precision requirement.  
  Space Saving  
  External circulation system, it don't need to have at least one end with complete thread to the end of Ballscrew for Ballnut assembly to screw shaft. And the special design of ballnut, so the size of ballnut is same as internal circulation system of ballnut, Space saving.  
  By way of 3D Spline designed pathway for circulation system, and has enhanced the smooth circulation of ball ,that can reduce the wearing and increase the life of ballscrew.
