According to a recent study by Deloitte, the aerospace and defense industry stands at a pivotal crossroads as it enters the latter half of the decade. Forces that have shaped the sector in recent years—digital transformation, supply chain volatility, talent constraints, and geopolitical events—are converging with new catalysts such as agentic AI, emerging vehicles and the rapid evolution of autonomous systems. On the defense side, budgets are a key focus, with a growing emphasis on enhancing mission readiness. At the same time, defense priorities are shifting to accelerate the fielding of AI-enabled systems and collaborative combat aircraft. “Speed to field” is becoming the unifying metric across portfolios.

Consider the following scenario: guided by vision sensors, a robot spots a product on a moving conveyor, determines its exact position and, in one fluid motion, picks it up and places it into a waiting assembly, carrier tray, or shipping container. What human operators once found tiring—or at least tedious, the robot performs flawlessly, hour after hour, even long after its flesh-and-blood coworkers have gone home for the evening.

Operating for long hours, under extreme loads, in high temperatures and dusty environments, ongoing wear is a significant challenge for open gears. This can lead to unplanned downtime and reduced equipment life—creating a barrier to effective operations. Leading mining and cement companies use advanced grease technology and technical inspections to help prevent open gear failure, optimize service life and ensure the smooth running of their operations.

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.

Motion + Power Technology (MPT) show brings together the gear and power transmission industries for a unique balance of education, new technologies and networking opportunities. The show takes place October 17-19,2023 in Detroit.
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.
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.
Selecting a drive, whether for a new application or to replace an existing one, doesn’t have to be a traumatic experience. The key to success lies in asking a logical sequence of thoughtful questions.
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!
Discover how Regal Rexnord’s Bauer™ PMSM gear motor helped a transportation company streamline inventory, cut energy use, and save $80,000 annually. Learn how this scalable solution delivers financial, operational, and sustainability gains across facilities.
The robust performance of the robot welder at Centerline Brackets led the Florida-based manufacturer to an exceptionally rapid return on investment, achieved in less than three months. The Universal Robots' collaborative robot dramatically cut production time and addressed labor shortages while ensuring consistent weld quality for heavy-duty brackets.
