Industrial sliding
Introduction
A linear motion slide or linear slide (also known simply as guide, slide and linear motion bearing) is a bearing designed to allow the movement of an object in a given direction. There are many different types of rectilinear motion sliders.
Motorized linear carriages, such as those in early electric typewriters, All linear slides provide bearing-based linear motion, whether ball bearings, dovetail slides, linear bearings, magnetic bearings, or fluid bearings. X-Y tables, various machine slides, and other advanced slides use linear motion bearings to provide motion along the

Un rodamiento generalmente se compone de un anillo exterior en forma de manguito y varias filas de bolas retenidas por jaulas. Estas jaulas se mecanizaron originalmente a partir de elementos macizos, aunque se reemplazaron rápidamente por piezas estampadas más ligeras. Presenta un movimiento suave, baja fricción, alta rigidez y larga vida útil. Son dispositivos económicos y fáciles de mantener y de reemplazar. Thomson Industries[1] (actualmente propiedad de Altra Industrial Motion[2]) se considera que fue el primer productor de lo que ahora se conoce como un rodamiento de bolas lineal.
Los rodamientos de elementos rodantes se fabrican en dos formas: correderas de rodamientos de bolas y correderas de rodillos.[3].
Ball bearing guides
Also called "ball sliders," they are the most common type of linear sliders. They allow smooth and precise movement of a linear displacement with respect to a single axis, with the help of ball bearings housed in the linear base, with self-lubricating properties that increase their reliability. Ball bearing slide applications include precision instruments, robotic assembly, electrical cabinets, high-end appliances and clean room environments, primarily serving the manufacturing industry, but also the furniture, electronics and construction industries. For example, the furniture industry widely uses ball bearing drawer slides.
Commonly constructed of materials such as aluminum, hardened cold-rolled steel, and galvanized steel, ball-bearing slides consist of two rows of balls contained by four rods and located on either side of the base, which support the carriage through the smooth linear movement of the balls. This low friction linear motion can be driven by a drive mechanism, inertia or manually. Ball bearing guides tend to have a lower load capacity for their size compared to other linear guides because the balls are less resistant to wear and abrasion. Additionally, they are limited by the need to fit into the housing or drive systems.
