Realizing the High Precision Load Handling Benefits of Rodless Electromechanical Actuators
Electromechanical rodless linear actuators can offer better load handling in smaller spaces than rod-style actuators, but realizing those benefits requires careful attention at the specification level. Whether you are replacing a failed actuator, looking for better performance or building a new application from the ground up, success depends on how precisely you specify application requirements.

Hannover Messe 2019
Manufacturing Integration and Industrial Intelligence Take Center Stage in Germany

Gears, Fluid Power and Electric
The American Gear Manufacturers Association has evolved its trade show. What was formerly Gear Expo is now the Motion + Power Technology Expo (MPT Expo), an event intended to represent the entire motion and power transmission supply chain. As part of the expansion of the show’s scope, AGMA has partnered with the NFPA (National Fluid Power Association) to include a fluid power pavilion and additional educational sessions.

Heavy Industry and Smart Technology
Heavy industry. The phrase conjures images of mines and steel mills, of huge caverns underground, of cavern-like factories, of oldline companies operating heavy-duty machines for hightorque work. That's the image of heavy industry. Today, though, there's also another image. It's of an operator walking a steel mill's floor, looking at his smartphone or his tablet.

Design Investigations and Indications for Acoustical Optimized Gear Meshes Using Plastic Gears
When it comes to a steel-gear mesh, there are several common standards and design rules on how to reduce noise emissions in the mesh. But if plastic gears are involved, this is no longer the case. The topic of this presentation is to highlight some of the differences between metal-and-plastic gear meshes, i.e. which design strategies can be stated as valid for metal as well as plastic and which are not?

Improperly Testing Belt Tension Can Easily Damage Small Motors
Most of us want to just instinctively squeeze a belt between a pair of pulleys to test the belt tension. What is not as instinctive is just how much force such a procedure can put on the shaft -- often significantly past the manufacturer's rated limits for small motors. This can cause damage to both the shaft and the bearings.

Everything is Connected (Publishers Page)
The theme of this issue is integration. Mechanical components are being developed with embedded sensors. The components are talking to each other, sending information to the cloud and producing terabytes of big data to help manufacturers better understand their processes, predict problems and control costs.

Ask Pneuman (Power Play)
Escape Rooms have been popular in recent years for their challenging game play, group participation and unique time constraints. Teams have X amount of time (typically 60 minutes) to solve puzzles, ponder riddles and dissect clues in order to escape a variety of themed games. Here's an escape room with a fluid power twist.
