I would like to briefly discuss some thoughts on ball bearing efficiency specifically in terms of applied load and resulting stress. I don’t want to trivialize this subject; there are textbooks written on the subjects of electrohydrodynamic lubrication (EHL), octahedral subsurface shear stress and friction losses due to elastic hysteresis. This is a just a high-level discussion on the importance of individual bearing stress on efficiency. 

Closed Loop control systems can handle a wide range of motions with a wide range of loads if the control system and mechanics 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 rather how to also get the desired performance.

The increasing cost of food and beverage machinery makes running equipment to failure not just impractical, but potentially devastating to your bottom line. However, there are solutions that can lead to significant savings, and an often overlooked one is implementing an effective lubrication program. A well-structured program delivers a trifecta of benefits: reduced downtime, a cleaner and safer work environment, and easier compliance with the stringent regulations of the food processing industry. 

Recently I’ve had a number of people tell me how much they enjoy our work here at PTE. While it’s always nice to receive “attaboys,” these recent unsolicited compliments have been both thoughtful and specific, which is especially gratifying because they validate many of the choices we make as publishers. 

At InnoTrans, SKF showcased tapered roller bearings for enhanced reliability of gearbox applications and cylindrical roller bearing units for increased longevity of freight train wheelsets.    

The Power Transmission Distributors Association (PTDA) welcomes new distributor member Eastern Sales and new associate member Proton.ai.

Global challenges and industrial competitiveness are having an impact on the training and continuous education of skilled workers and students. In addition to theoretical principles, practical knowledge is also in demand, particularly with regard to digitized and networked manufacturing processes. Virtual learning factories based on 3D simulation platforms offer interesting possibilities when it comes to Industry 4.0: The Mechatronic Simulation Wall developed by MHJ Software GmbH & Co. KG is a mirror image of real mechatronic systems and can include up to four different stations, e.g. magazine, processing, quality assurance and sorting. This type of configuration makes it possible to program each station individually, or run the entire system, which opens up a wide range of learning scenarios with varying degrees of complexity.

Mantis, a provider of warehouse management and logistics solutions, is delighted to announce the appointment of Nikos Silivestros as its new CEO. Silivestros possesses extensive experience and a proven track record of driving organizational growth and leading teams to notable achievements, particularly within the supply chain industry.

Coverage of IMTS and MINExpo International will continue on the PTE website through the end of the year and into 2025. We're excited to share the stories and new technologies discussed at both trade shows in September.
