igus has developed a new lead screw configurator that allows users to quickly design their own lead screw and associated drawing without in-depth technical knowledge and CAD software. Designing a lead screw usually requires significant effort for the user, who is required to have technical drawing skills and access to a CAD program. The new […]

The LinX M-series linear motor features an integrated position […]
igus belt drive actuator lowers automation costs
New lubrication- and maintenance-free toothed belt drive actuators from igus can significantly reduce the costs of automation tasks such as pick-and-place, inspection, and assembly applications. High speeds, high load and precise positioning accuracy are not required in every application, such as format adjustment and vision system positioning. Many solutions in the market are oversize, however, […]
Festo at Automate 2019: OEM productivity-boosting solutions
Festo is showing electric and pneumatic motion-automation solutions at Automate 2019 April 8 to 11 at McCormick Place in Chicago — Booth 8151. Productivity-enhancing solutions include company-wide component interoperability and online tools for designing subassemblies that slash OEM engineering overhead and reduce delivery time. With the Festo Handling Guide Online, engineers can design single-axis or […]
When do synchronous belts need flanged pulleys?
Synchronous belts transmit power via positive engagement between profiled teeth on the belt and pulley. Although this tooth engagement (along with proper belt tension) prevents the belt from ratcheting, the belt is free to track, or move side-to-side, on the pulley. To prevent the belt from riding off the pulley, and to resist the lateral […]
Update on roller-screw actuator design and applications (with video and image galleries)
Roller screws are also called planetary roller screws or sometimes satellite roller screws for how their nut-encased rollers orbit the drive-shaft axis during operation. These mechanical rotary-to-linear devices work in an increasing number of electromechanical actuators. Satellite roller-screw geometry includes far more internal contact between load-bearing subcomponents than their ballscrew cousins, and that boosts rigidity […]
Motion Trends: Applications expand for versatile lead screws
Improvements in lead screw designs have meant screws that are increasingly competitive with other types of drive screws, including ball screws. For instance, lead screws can offer shorter lead times and better performance, all at a lower cost than other screw technologies. Quite a few lead screw manufacturers offer a range of anti-backlash options, superior […]
New 20-mm linear stepper motor now available from Nippon Pulse
Nippon Pulse now sells the the PFL20 Linearstep — its smallest linear stepper motor yet. The PFL20 is a highly efficient, high thrust tin-can linear actuator with a 20-mm diameter and a bipolar winding. PFL20 is RoHS-compliant, has a 30/60-mm effective stroke, and can reach 6 N of force at 200 pps. With 24 steps […]
Motion Trends: Ball screws pack more load capacity
Continued developments in manufacturing and materials have improved ball screw performance, with the most recent generation of ball screws having greater load densities than ever before, leading to higher load capacities. High-load ball screws are being integrated into electromechanical linear actuator systems for use in applications with higher loads and more demanding environmental conditions. In […]
What are linear induction motors?
An induction motor is one in which the current in the rotor is induced by the electromagnetic field in the stator, eliminating the use of magnets. A linear induction motor is a type of linear motor based on a rotary AC induction motor. Like permanent magnet linear motors (commonly designated as “ironless” and “iron core” types), […]
