Speed is of the essence for packaging machines: Products must be filled, reliably sealed, and prepared for shipping in the shortest possible cycles. Ideally, maintenance and unplanned downtime are rare to keep the total cost of ownership low. The list of requirements is long and applies to the packaging machine itself and its components, such […]
Linear drives (all)
Part 2 of 2: Update on electrification
In the first installment of this series, we covered the reasons why off-highway applications are primed for electrification — especially those vehicles with lots of axes that deliver relatively slow yet high-torque (or force) motion. Where the axes on a piece of off-highway or other equipment are linear, electric actuators have in some cases replaced […]
Three strategies for selecting the right electric linear actuators
By following a few best practices, machine builders can design automation systems that increase equipment availability, achieve new levels of performance, and elevate product quality. Florent Orget Actuator Product Marketing Manager Emerson As more manufacturers digitally transform and automate their production lines, they are gaining a clearer picture of their operations and machine health. And […]
Electroadhesive brakes provide stopping power for linear motion systems
How paper-thin electroadhesive linear brakes can unlock significant power and weight savings in new and legacy linear motion systems. Kirby Witte VP of Engineering ESTAT Actuation Linear motion systems must pack all the right features and components in increasingly compact designs. Brake technologies are a critical part of this puzzle, providing load holding, emergency stopping […]
Pre-loaded systems deliver precise positioning for machine tools
Redex’s patented DualDRIVE and TwinDRIVE preloading technologies now give CNC machine designers several ways to build a zero-backlash system. These approaches leverage Redex modular SRP, DRP, KRP and KRPX Series rack and pinion reducers whose output pinions are preloaded against the rack to eliminate backlash — a longstanding challenge with designs that require long axis […]
Omega Drive technology outputs linear or rotational motion
RUD’s new Omega Drive is a new chain drive with a 180° wrap angle. From the Tecdos series, it is suitable for both linear and rotational motion — capable of rotating, lifting, and lowering loads in various on and offshore settings. Applications include shifting harbor and ship cranes, relocating machinery, and solar panel sun tracking. […]
How linear motion technology is meeting the challenges of tomorrow
To meet the complex factory automation challenges of tomorrow, linear motion systems are evolving to become quicker, more economical, and more sustainable. Kevin Straub Bosch Rexroth Linear motion components are central to the functioning of a host of machines and mechatronic systems. They enable reliable guidance, precise positioning, and advanced handling capabilities. Such features are […]
Increased speed with new planetary screw assembly
New intermediate size of the proven planetary screw assembly from Bosch Rexroth achieves double the linear travel speed and cycle time at the same rotary speed New intermediate size 48×20 for high-power applications Higher transmission ratio shortens cycle times and increases productivity Quick product selection and online configuration using e-tools The ongoing trend towards electrification […]
Leadscrews in medical equipment
Leadscrews are essential to surgical robotics, patient-monitoring systems, diagnostic imaging devices, and rehabilitation equipment. By Chris Nook | Chairman and CEO • Helix Linear Leadscrews are those spiral shafts that (upon application of torque) convert rotational motion into linear motion — axially advancing and receding a mating nut to deliver accurate positioning. They’re well suited […]
Integrated linear-motion variations becoming the norm
Automation over the last several years has expanded use of electric linear actuators to leverage their technological advancements in smart homes, aerospace, defense, and industrial applications. In fact, the global linear actuator market could (in large part because of electric options) surpass U.S. $52.67B this year and grow at a compound annual growth rate through […]
