For years, the cycloidal reducer (Figure 1) has proven its performance in a variety of applications, from robotics to wastewater treatment. Along with involute gearing, the cycloidal mechanism has its place in the mechanical power transmission world. It is well known for its high torque density, high integer ratio per stage, and shock load handling capabilities. Its poke-yoke assembly refrains from introducing any errors during assembly and allows the unit to operate with low maintenance. Despite these advantages, the reducer may have a variable angular speed at its output shaft, in large part due to manufacturing imperfections.

Testing is a powerful tool for improving equipment reliability and reducing the risk of costly, unplanned downtime. When a bearing fails, it’s important to figure out why. Without an investigation or testing to determine the cause, there is a greater likelihood that the same problem will happen again. That’s why SKF Global Labs and Testing plays such a critical role in helping customers maximize the performance and service life of their rotating equipment.

Airports where hundreds of airplanes take off and land around the clock require perfect planning and coordination—and the tailor-made drive technology to process thousands of passengers and their baggage securely, every day. The growing focus on capacity and security issues, as well as shorter ground times, are presenting major challenges for the airport industry.
In the highly competitive gear manufacturing industry, Master Power Transmission (MPT) recognized the need for innovation. To achieve this, MPT partnered with Ready Robotics, undertaking a transformative journey into advanced automation through their Automation Readiness Assessment (ARA).
As industries adopt more automation, the demand for reliable and efficient pneumatic systems, which power everything from robotic arms to air-powered tools, continues to rise. However, despite their widespread
use, these systems often suffer from hidden inefficiencies. Here, Chris Johnson, managing director at SMB Bearings—Oxfordshire, U.K.) explores how an overlooked component, industrial bearings, can improve the
efficiency of pneumatic technologies.
The trade show circuit has offered a wealth of e-mobility and motor technologies recently. From IMTS and Pack Expo to MINExpo and CES 2025, there are plenty of disruptors in the motor segment for power transmission components. One area—in particular—is the aerospace industry where vertical takeoff and landing (VTOL) rotorcrafts continue to redefine aerial transport, variable frequency drives (VFDs) support aircraft performance, stepper motors provide passenger comfort and software enables engineers to optimize electric motor design.
