A linear-motion bearing or linear slide can be a bearing designed to provide free motion within a dimension. There are many types of linear motion bearings.

Motorized linear slides including machine slides, XY platforms, roller tables and a few dovetail slides are bearings traveled by drive mechanisms. Not all linear slides are power-driven, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear move for equipment powered by inertia or by hand. All linear slides provide linear motion influenced by bearings, whether they are ball bearings, dovetail bearings, linear roller bearings, magnetic or fluid bearings. XY Furniture, linear stages, machine slides and also other advanced slides use linear motion bearings to give movement along both X and Y multiple axis.
