The load limit diagram of a motor spindle serves to graphically represent the permissible operating range as a function of parameters such as rotational speed. It enables a quick assessment of the conditions under which the spindle can be operated safely and reliably without exceeding mechanical, thermal or dynamic limits. Such a diagram is a key tool for the design, selection and evaluation of spindle systems in mechanical engineering particularly in the field of machining where high demands are placed on precision, performance and service life.
The first Gear Expo featured 22 exhibitors at the 1986 Fall Technical Meeting in Chicago. It was billed as the “AGMA Fall Technical Meeting & Gearing Exhibition” and provided attendees the opportunity to learn the latest technical advances, state of gear research and gear design. The show highlighted machine tool, software and processing exhibitors to meet the ever-changing needs of the gear industry.

An innovative technology for the next generation of high-speed, high power density traction and propulsion systems has been jointly developed by Drive System Design (DSD) and Transense Technologies. David Hind, principal engineer, DSD, presented “Unlocking Powertrain Power Density with Innovative Motor Control,” earlier this year at the CTI USA Symposium 2025 in Novi, MI. The presentation built on initial simulation studies performed in MATLAB Simulink; a software tool used to design and simulate systems before moving to hardware. While simulation trials proved successful, achieving quality experimental results proved far more challenging. Hind examined these challenges and potential solutions at CTI.

Pack Expo Las Vegas, one of North America’s most comprehensive packaging and processing events is celebrating a milestone: 2025 marks 30 years since the show’s debut. Today, Pack Expo Las Vegas continues to be a global hub for industry innovation and collaboration. Show producer PMMI, The Association for Packaging and Processing Technologies, has elevated Pack Expo Las Vegas from a regional trade show to a global industry force—expanding its scale, influence, and relevance across international markets. This year, the show spanned over 1 million net square feet, featuring 2,300+ exhibitors.

The SKF Lincoln SL-6 metering device is a single-line automatic lubrication system injector. Its proven design is thoroughly updated to meet new demands on maintainability, leakage-protection and long-lasting performance even with harsh extreme pressure greases. Today’s manufacturing environment demands less maintenance time, higher productivity demands and little to no tolerance for unplanned production stops.

The path toward success in mechanical power transmission today hinges on an organization’s ability to provide smart and digital automation solutions. Customers are looking for system components boasting more performance, precision, and cost effectiveness in robotics and industrial automation applications. Schaeffler, the global technology company specializing in solutions for the automotive and industrial sectors, offers a strong and diverse product range not only for large industrial robots, but also for lightweight and collaborative robots (cobots).
The Houston Turbomachinery & Pump Symposia (TPS), still organized by the Turbomachinery Laboratory at Texas A&M University, will gather for the 52nd Turbomachinery and 39th Pump Symposium annual event from September 26–28, at the George R. Brown Convention Center in Houston.
The Bearing Show North America 2025, colocated with Lubricant Expo North America 2025 takes place March 18–20 at Huntington Place in Detroit. The Bearing Show connects the evolving needs of bearings end-users with the latest technologies serving OEM development, maintenance professionals and R&D engineers.
Automation has become a key driver of efficiency and productivity, regardless of industry. Among the most popular automation solutions are automated guided vehicles (AGVs) and autonomous mobile robots (AMRs). While both technologies automate and enhance material handling and reduce manual labor, there are key differences in their functionality, flexibility, and areas of application that set them apart.
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.
Bellows couplings are commonly used in applications requiring precise rotation, high speeds, and dynamic motion transmission. With zero backlash and a high level of torsional stiffness, they offer clear performance advantages in many servo-driven systems.
The Simplicity self-lubricating linear plain bearings are built to last, and they will often out-perform and last longer than a traditional linear ball bearing. Called the “little red bearing” by loyal customers, they have been a popular replacement for failing ball bearings. Simplicity plain bearings will not catastrophically fail.
The difference between a smooth-running drive and constant headaches? The right timing belt and pulley plus a whole lot more. Discover what works, what doesn’t, and put your design skills to the test—engineer your best system yet!

The Society of Tribologists and Lubrication Engineers (STLE) has entered into a strategic partnership with the Motion + Power Manufacturers Alliance (MPMA) to jointly develop and deliver content for the 2026 MPMA Fall Technical Meeting (FTM).
A new version of the MESYS shaft and rolling bearing analysis software is available. The bearing analysis software allows the calculation of the load distribution within the bearing as well as bearing life according to ISO 16281. It is integrated in a shaft system calculation offering additional capabilities such as modal analysis, strength calculation for shafts and interfaces to gear calculations.
