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. 

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.    

Nine months into building the most powerful test bench for main bearings to date, R&D Test Systems, Denmark’s wind turbine test specialist, has completed the 3,700 metric ton foundation and is now designing and welding the test bench parts that will perform extreme test loads on main bearings for 25 MW wind turbines. With delivery in 2025, the test bench is bound for LORC’s new main bearing test facility.

AD is proud to announce that Mark Balcom, president and owner of Pooley Inc., has been elected to its Bearings & Power Transmission Divisional Board, effective August 2024.  

CCTY (Lake Zurich, IL) is a manufacturer of high-performance motion control and assemblies including spherical plain bearings, rod ends, mast guide bearings, self-lubricating bearings, tie rods, ball joints and more. CCTY is a full-service global engineering and consulting partner that helps customers quickly turn new product ideas into reality. PTE recently discussed the company’s evolution with Yaman Obaid, a mechanical engineer specializing in robotics for CCTY.

MINExpo boasts 1,900+ companies involved in the global mining industry. Opening sessions allow the industry to come together to debate global challenges, market fluctuations and the future of mining. Resources include exploration, mine site development, open pit mining, underground mining, smelting and refining, processing and preparation and reclamation. Here’s a sample of the companies exhibiting and the products/technologies they will be featuring in Las Vegas from September 24–26, 2024.

The Timken Company has issued its corporate social responsibility (CSR) report, providing an update on the company's actions to improve the lives of individuals and communities, benefit the planet and strengthen its business.

NTN, the parent company of BCA Bearings, has announced the launch of the BCA Wheel Hub with Hardware Kits product line. The initial launch of this new product line includes 27 new SKUs for popular import and domestic applications and represents coverage for over 16.3 million vehicles in operation.

Physik Instrumente (PI) inaugurated the PI Technology Hub in Karlsruhe, Germany in July. On an area of 500 sqm, the hub offers space for ten employees of the central department “Global Research” as well as ten additional places for more extensive project work and for Ph.D. students and working students. It is equipped with special laboratories to allow for hands-on experiments. The strategic proximity to the Karlsruhe Institute of Technology (KIT) and other research institutions will promote an intensive exchange and close cooperation.
