Linear guides and rails provide a smooth, precision, guiding surface on which the rolling element of a linear bearing rides.
 

Linear bearings are available in many configurations, with differing attributes such as stiffness, smoothness of motion, profile height, cost, material, and rolling element type. Some of the more common types include crossed roller bearings, linear motion (LM) guides, bushing style bearings (plain bearings or with balls), needle roller bearings, roller bearings, splined shaft bearings, and various guide wheel configurations.
Material choices for linear guides and rails include aluminum, polymer or plastic, stainless steel, or steel. Material features include corrosion resistance, case hardened, thru hardened, and not hardened. Important dimensions to consider include guide width or diameter and guide length. Features common to linear guides and rails include continuously or intermittently supported, end-supported, clean room ruse, pre-drilled holes, self-aligning, and vacuum compatible.
