Abstract Since precision and productivity of machined products directly depend on the performance of a machine tool spindle such as for a machining center, the spindle is an especially important component. So, spindle bearings are always required to have high performance and reliability. Here recent trends in machine tools and their spindle bearings are presented. And then, new technology required for further development of spindle bearing for machine tools is also presented.
