Linear guide systems and components transport loads along a linear axis. They provide precise movement in applications like industrial automation, robotics, assembly, and testing equipment. Linear guide rails mount on surfaces to hold and keep carriage systems evenly aligned. Ring slide guide rails facilitate smooth gliding in rotary and track system applications. Linear guide carriages and slides move medium-to-large loads at high or low speeds. Heavy-duty linear cam roller bearings support heavy loads and are suitable for applications that operate continuously, get dirty, and require a long service life. Linear bearing guide components maintain, repair, or replace linear bearings and carriage assemblies. Linear guide rail and carriage slide assemblies include a guide rail and compatible carriage. Miniature linear guide rail and carriage assemblies have compact construction for small-load applications with limited space.
