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.

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.

Despite a lukewarm sustainability agenda here in the United States, global bearing manufacturers continue to be motivated by eco-friendly technologies, environmental awareness and energy efficiency regulations. Material innovation is one of the key strategies to reduce environmental impact moving forward. Concerns include energy consumption in manufacturing, waste generation, emissions from lubricants and raw material extraction. The end goal is to provide longer-lasting components with less waste.

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.

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.
Atlanta Drive Systems, Inc., Farmingdale, NJ, offers rack and pinion systems, actuators, gearboxes, servo reducers and lubrication systems for many different industries including machine tool, automation, aerospace, woodworking, material handling, robotic, food, packaging, stone and special machinery. PTE recently discussed the company’s lubrication solutions with Peter Alfano, senior applications engineer.
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.
More energy efficiency, higher performance and better controllability are the main reasons why more electric drive systems are being operated with frequency converters. However, these devices can cause high-frequency, asymmetrical interference currents, which, as a current passage through the output and fan-side bearings, can cause damage and premature failure.
Current-compensated CoolBlue toroidal cores made of Magnetec’s nanocrystalline material Nanoperm have proven to be effective protection against such conducted interference and its consequences. In addition, the Nanoperm Line Absorbers NaLA can also be used to significantly suppress symmetrical interference currents.
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.

ZF’s Commercial Vehicle Solutions division secured an order from an original equipment manufacturer in India for its next-generation AxTrax 2 LF electric portal axle. The multiyear agreement includes the delivery of several thousand units destined for the Indian domestic market as well as global exports.
Parts even smaller than the “nano” are possible with the NanoOne 3D printer from UpNano. Light particles are fired at the starting material and this process plays out over a range of thousandths of a millimeter. Three compact, high-performance motors from Faulhaber ensure the correct position. The structures that UpNano produces in the 3D printer are so small they are only recognizable under a scanning electron microscope. These structures are used in medical experiments as a framework for living cells, or as microfilters, microneedles or microlenses.
