Linear-motion bearing. A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings. Motorized linear slides such as machine slides, XY tables, roller tables and some dovetail slides are bearings moved by drive mechanisms.
Screw driven, ball guided positioning linear slides are designed for robust applications that demand high thrust along with high-precision accuracy and stiffness. This configuration of drive and guide is just one of several pre-assembled, ready-to-install linear slides available to mechanical motion engineers.
