A linear-motion bearing or straight slide is a bearing made to give cost-free motion in one direction. There are many different sorts of direct motion bearings.
Mechanized linear slides such as maker slides, XY tables, roller tables and some dovetail slides are bearings relocated by drive devices. Not all straight slides are motorized, as well as non-motorized dovetail slides, sphere bearing slides as well as roller slides give low-friction direct movement for tools powered by inertia or by hand. All direct slides supply direct motion based upon bearings, whether they are sphere bearings, dovetail bearings, linear roller bearings, magnetic or fluid bearings. XY Tables, direct stages, machine slides as well as various other sophisticated slides use linear movement bearings to provide movement along both X and Y multiple axis.
