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.

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.

Collaborative robots have been hugely beneficial for manufacturers of all sizes over the past 15 years, and their share of the total robot market continues to grow every year. As of 2025, hundreds of different cobot models are available from dozens of manufacturers. Today, we will discuss the differences between industrial and collaborative robots, advantages of cobots, typical cobot applications, case studies, and some specific robotic solutions.

This article is Part III in a series of articles on speed rating of bearings. Part I appeared in the September 2022 issue ("Ball Bearing Limiting Speeds"), and Part II appeared in the October 2022 issue ("Ball Bearing Thermal Speed Rating"). Bearings with Norm examines the latest in bearing technology and design.
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.
Rolling bearings possess especially low friction characteristics. They make it possible to reduce bearing friction by half, offering the construction machinery sector the opportunity to achieve significant carbon dioxide savings without imposing high development costs. This article will examine the current solutions from Schaeffler.
It’s an exciting time in the electric motor industry. In the past two years more truly innovative new technology development has occurred than in the previous two decades. We can thank the e-mobility movement for that. It’s not just cars, trucks, bikes and buses, but just about everything else that moves on wheels as well as on water and in the sky.
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.
With the goal of building a full lineup of actuators for every joint required in robot construction, Bonsystems has been developing robotic actuators and introducing the BCSA V4 Series. The BCSA Micro Series is a Cycloidal Micro Actuator designed specifically for robotic hands.
