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.

Cartesian And Six-axis: Which System Is Best For...

As more manufacturers automate their operations to improve productivity and competitiveness, different robotic systems have become available to perform a diversity of production tasks. Cartesian systems have been a workhorse in production facilities, while systems with articulated arms — such as the increasingly popular six-axis robot — have emerged to handle more nimble tasks. Depending on the application, there are clear rationale for using a Cartesian and clear rationale for using a six-axis system. Here’s an overview of the advantages and disadvantages of each so you can select the right one based on your application needs:
