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.
NASA’s successful Artemis II mission represented the first crewed lunar mission since Apollo 17 in 1972 as well as a major leap forward in humanity’s return to deep space exploration. The mission launched on April 1, 2026, and lasted approximately nine days, one hour and 32 minutes.

The belt and chain market is heavily driven by intralogistics, automation and infrastructure growth in 2026. Manufacturers are looking at areas like electrification, sustainability and supply chain resilience to meet stricter performance expectations. PTE recently sat down with Kyo Oh, vice president and general manager at AMMEGA Group Power Transmission and Fluid Power Solutions, to discuss the U.S. belt market from a power transmission perspective.

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.

Gear drives are fundamental in most processing operations, connecting the prime mover to the driven equipment and ensuring that the system has enough torque to effectively move product. Correctly specifying and selecting the proper gear drives for critical applications leads to reliability, greater uptime and profitability.
The Danish company FLSmidth wants to be in constant dialogue with their customers in the mining and minerals industry to develop individual and pioneering solutions for better productivity as well as the responsible and efficient use of natural resources. As the drive is the heart of the crusher, the bevel gear is one of its most important components, making gear quality crucial to the design and manufacture of reliable crushers. This means that FLSmidth wants to use only the best and most reliable partners to supply those gears.
Greetings 2026! As expected, EV demand has waned following some deregulation and tax credits being dropped as of September 2025. For us industry folks, this is simply reality catching up with the narrative. On the plus side, 2025 was a very good year for global vehicle sales–the best since 2019 (Ref. 1). A good economy can forgive many blunders. As gearbox designers, our work continues as our EV offerings are likely a permanent part of our product lineup, even if at a reduced volume.
In a belt drive system, the motor, belts, pulleys, and sheaves all receive engineering attention during design and specification. The motor base typically does not. It is the overlooked component, selected on frame size and bolt pattern, specified late in the process, and treated as a passive structural element, something that holds the motor in place and sets belt tension at installation.
