Choose Linear Motion Guides and Actuators to...


As companies strive to move goods rapidly, accurately and efficiently, they’re breaking with conventional distribution methods and investing in automated storage and retrieval systems for their operations. These new, automated systems include shuttles that pick and place products, stacker cranes that run on both a horizontal and vertical axis and vertical warehouses that store and move materials on different shelves using automated mechanisms.

Ball Screw Versus Belt-Driven Actuators: Which Is...


When a machine design calls for a motor-driven linear actuator, choosing between a ball screw or belt-driven unit will depend on how its characteristics align with your application’s goals. That means carefully comparing the advantages and disadvantages of each to avoid specification errors and ensure optimal performance. The main trade-off designers need to address at the outset is actuator speed versus repeatability. The comparison should also include various loads and forces the actuators must handle along with the application’s stroke requirements. Those factors are presented here along with other considerations as you begin to evaluate linear actuators for your application, using Rollon actuators as examples.
