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.
Leaders from across the construction and heavy equipment manufacturing industries gathered in Las Vegas recently for ConExpo-ConAgg 2026. The show celebrated the innovation, economic impact and workforce powering the $2.2 trillion U.S. construction sector today.

Drones are tasked with providing state-of-the-art autonomous capabilities, unique movements, automated inspection, urban delivery solutions and advanced military operations. They upgrade agricultural farming technology, provide safety and logistic solutions and report key disaster and engineering mapping. PT components such as motors, controllers, and sensors are an integral part of their core structure.

For worm gearboxes, oils are mainly used in combination with splash lubrication. Consistent lubricants, such as greases, are used less frequently and are used, for example, in gearboxes where it is not possible or difficult to seal the housing (Ref. 1). These applications include positioning gears, but also power gears with high sealing requirements, such as in the food industry. Grease lubrication has, in comparison to oil, a negative thermal effect on the worm, resulting in higher mass temperatures (Ref. 2). However, this effect becomes less relevant in the application of positioning gears, so that the advantages of grease lubrication outweigh the disadvantages in these applications.
The digital transformation is fundamentally changing the industry, and digital twins play a central role. They enable real-time monitoring of physical systems, simulation of their behavior, and informed decision-making. A dissertation from the TU Darmstadt Institute for Product Development and Machine Elements (pmd) shows how the FVA-Workbench gearbox design software can be implemented as a platform for creating digital twins of industrial gearboxes. The results demonstrate how the combination of detailed modeling, continuous real-time calculations, and engaging dashboard visualization offers an efficient and user-friendly solution for the development of digital twins.
Schaeffler continues to advance key technologies shaping the future of mobility and motion. One area of interest—humanoid robots—is where Schaeffler is developing advanced component and system capabilities for the next generation of robotics. PTE recently had the opportunity to discuss these technologies with Al Makke, engineering director, humanoid robotics, North America, at Schaeffler Group USA.
Closed Loop control systems can handle a wide range of motions with a wide range of loads if the control system and mechanics are properly designed for the task. A couple of the more difficult combinations to design for are high inertial mismatches and backlash with hard gearing. The question is not just how to make the system stable, but rather how to also get the desired performance.
How does a ball screw work differently than a lead screw. Under what circumstances would a ball screw be better for your application than a lead screw. What issues should be considered when selecting a ball screw assembly.
Napoleon Engineering Services’ “Brief Guide to Bearing Source Qualification” is the result of nearly 30 years of real-world experience guiding OEMs through the qualification process and is based on NES’ background in the aerospace and industrial sectors and its own desire to empower customers with the technical information needed to make informed supplier decisions.
Push beyond traditional 60Hz limits with advanced VFD strategies like field weakening and motor supercharging. Expand speed range, improve system stability, reduce cooling requirements, and even downsize motors. Discover how to unlock more performance and efficiency from your gearmotor design.
Spiroid Gearing delivers precision gearing for advanced mechanical systems, engineered to handle extreme torque and complex motion requirements. With unique right-angle gear solutions, our technology enhances efficiency, reliability, and design flexibility - empowering engineers to push boundaries in aerospace, defense, robotics, and industrial applications where performance and durability are non-negotiable.
The drive system choice is dependent on key motion features of your application. Lead screws offer self-locking capabilities, while ball screws require brakes to prevent back-driving. The choice between them hinges on efficiency, cost, precision, and speed, with the screw drives themselves paired with a linear guide for optimal performance.
Linear Slide Guides with a tall profile linear rail resist bending under load, thus enhancing rigidity. Their angled rail surfaces prevent debris accumulation, making them ideal for contaminated environments and cleanrooms

North American companies ordered 9,055 robots valued at $543 million in the first quarter of 2026, according to new data released by the Association for Advancing Automation (A3). Compared to the first quarter of 2025, this represents a 0.1 percent decrease in units ordered and a 6.4 percent decline in revenue. While unit orders were essentially flat, order revenue declined year over year, driven largely by a cyclical decline in Automotive OEM orders, which fell 35.1% in units and 48.2% in revenue compared to the same quarter last year. Given the size and timing of automotive programs, that decline had an outsized impact on the total market.
This week at SPS Italia, Bonfiglioli presents its full mechatronics ecosystem, integrating gearmotors, inverters, condition monitoring, predictive maintenance, and advanced automation software tools.
