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 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.

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 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.

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.

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.
This study presents a simulation method for considering complex wheel bodies in an analytical tooth contact model. The wheel body is considered using reduced FE stiffness. Reduction points are defined over the width and linked with the analytical gear.
For cylindrical wheel bodies, comparative calculations show fewer deviations from the expected results with the new method. This is due to the additional degrees of freedom in the FEM model. In the calculation with cylindrical wheel bodies, bending due to axial force in tooth contact could also be verified in addition to the deformation in tooth contact and the influence of the shaft-bearing system.
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.
The mining industry relies heavily on efficient and reliable equipment to process large volumes of ore and mineral resources. One critical component in this ecosystem is the grinding mill, which plays a pivotal role in comminuting materials to prepare them for further processing. Grinding mills, particularly the large semi-autogenous (SAG) and ball mills, often operate under challenging conditions that demand precision, durability, and adaptability. A key technology enabling these mills to operate safely and efficiently is the hydraulic inching drive system.
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 Chair of Production Engineering of E-Mobility Components (PEM) of RWTH Aachen University has entered the two-year “NAFTech” research project funded by the German Federal Ministry for Economic Affairs and Energy. Together with the Institute of Electrical Energy Conversion (IEW) at University of Stuttgart and the Chair of Manufacturing Automation and Production Systems (FAPS) at FAU Erlangen, the PEM team will be developing an electric motor as a traction drive that does not require the use of rare-earth elements and will still offer a great degree of compactness, efficiency, and high torque density.
Turntide Technologies (Turntide) will unveil the Turntide Axial Flux Electric Drive Unit (EDU) during CONEXPO-CON/AGG (CONEXPO). This Axial Flux EDU provides electric and hybrid system manufacturers of any size with a configurable, proven and scalable platform that can remove months, if not years, of component-level testing, decreasing time and cost to market.
