=Introduction= 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, X-Y tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand. All linear slides provide linear motion based on bearings, whether they are ball bearings, dovetail bearings, linear roller bearings, magnetic or fluid bearings. X-Y tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
=Challenges= Static structures are not sufficient for reproducing most useful objects.
Bearings introduce backlash unless preloaded.
=Approaches= Bearings allow frames a variety of motion in relation to each other and other components.
To use the captive hex holes, insert bolts from the inside of the linear bearing, pointing out toward the frame. <gallery> Linear bearing notes.jpg|Notes Linearbearing1.jpg|Linear bearing Linearbearing2.jpg|Linear bearing Linear bearings 1.jpg|Linear bearing Linear bearing 2.jpg|Linear bearing Linear bearing 3.jpg|Linear bearing Linear bearing 4.jpg|Linear bearing Linear bearing 5.jpg|Linear bearing Linear bearing 6.jpg|Linear bearing Linear bearing 7.jpg|Linear bearing Linear bearing 8.jpg|Linear bearing Linear bearing 9.jpg|Linear bearing Linear bearing 10.jpg|Linear bearing Linear bearing 11.jpg|Linear bearing Linear bearing 12.jpg|Linear bearing Linear bearing 13.jpg|Linear bearing Linear bearing 14.jpg|Linear bearing Linear rail mount.jpg|Linear bearing rail mount Fabricated linear bearing.jpg|Fabricated linear bearing </gallery>
