Abstract
This paper describes some new technologies on Linear Motion guide for machine tools. This Linear Motion guide should be satisfied with the requirements of performances and ecological behavior requested by machine tools engineer and end-user. As for performances, static stiffness, running accuracy and good economy are major concerns for machine tools engineer. As for ecological behavior, there exist some aspects. These are "Low emission from machine to environment", "Resistability against solvents provided inside the machine" and "Human friendly characteristics".
