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.
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.

UGRacing is the University of Glasgow’s Formula Student team. Since its inception in 2005, the team has been working to compete at Formula Student UK (FSUK). Over the last decade, the team has grown to over 150 members across ten disciplines. With a strong focus on knowledge transfer and iterative design, the team has worked year after year to develop new technologies and a more refined package. In 2022, the team saw a culmination of all their hard work when they placed first overall in FSUK with their final internal combustion vehicle. The following switch to an electric powertrain brought new challenges. Through the constraint of a new powertrain architecture, the team has explored and innovated drivetrain concepts which, in future years, will improve vehicle performance.
Future electric and hybrid electric vertical takeoff and landing vehicles will require high-efficiency and lightweight electric motor-driven propulsion systems. One key to designing an optimum electric motor-driven propulsion system, is to have a method for estimating the mass and efficiency of a gearbox for different power levels, motor speeds, and propeller speeds. Understanding the trade space for gearbox mass and efficiency allows the overall optimization of the propulsion system.
Between trade shows including MINExpo and CES 2025, we’ve been treated to a great deal of new technology in areas like mining, agriculture, construction and heavy industrial components. Liebherr has modified its component portfolio to include digital measurement, electrification and maintenance-free technologies. Liebherr’s component product segment offers advanced solutions for slewing bearings and slew drives that meet the rising demands across a variety of applications and industries. These components are future-ready and play a vital role in making operations much more efficient.
Closed-loop control systems can handle a wide range of motions with a wide range of loads if the control system and the mechanics of the system 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 also how to get the desired performance.
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.
Design engineers are always on the lookout for efficient and reliable application solutions. While standard products often suffice, some challenges demand a custom approach. Custom machine couplings, critical for torque transmission between a machine's driving and driven components, require careful consideration of specific requirements to guarantee optimal performance and unwavering reliability.
Precision elastomer insert couplings offer vibration damping, easy installation, zero backlash transmission, and electrical isolation. Fitting a wide variety of drive applications including lift systems, conveyors, pumps, linear actuators, and high performance general power transmission.
