MOTION DESIGN GUIDE ON LINEAR GUIDES
Linear-motion systems are essential in everything from manually operated industrial drawers to advanced Cartesian robots. Mechanisms that include the former operate without power, using inertia or manual power to move loads. Components to complete the latter include ready-to-install drive and guidance designs … in the form of self-contained actuators or linear-motion machinery subsections. Some designs simply rely on the rotary-to-linear mechanism or actuator structure for total load support. However, most industrial linear designs have pneumatics, linear motors or motor-driven, rotary-to-linear mechanisms to advance attached loads, as well as rails that guide and support the loads.
In this Design Guide, the editors of Design World detail the linear rails, guide rails, linear slides and linear ways used to facilitate single and multi-axis linear motion — and the disparate ways these components support and guide load with minimal friction along the way.
