Popis:	The authors have reported in a previous paper that the twist-roller friction drive can realize sub-nanometer positioning resolution. However, a structural difficulty of the device is that hydrostatic bearings are used to support the twist-rollers. The present paper describes how the structure of the twist-roller friction drive can be simplified by using ball bearings to support the twist-rollers. Even with this simplification, the experiments showed that the positioning resolution is less than one nanometer. The paper concludes that the twist-roller friction drive of ball bearing type facilitates the manufacture of a nanometer positioning system which can be used in a clean environment, and can take the place of the ball screw or capstan friction drive.
