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.
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.
Mark your calendars for March 19–21, 2024, as the Bearing Show—colocated with Lubricant Expo—descends upon Huntington Place in Detroit. As North America’s premier exhibition and conference dedicated to bearings, this free-to-attend event promises to be a groundbreaking convergence of industry leaders, technological advancements, and invaluable networking.
With an “all-hands on deck” approach to maintenance today, engineers require the latest tools and technologies in the form of new software/apps to make MRO tasks easier. Turns out, technology is allowing your smartphones, tablets and computers to track bearing reliability and performance with an emphasis on sustainability, longevity and analysis.
Manufacturing, chemical processing, food and beverage, construction, mining, oil and gas, agriculture, and power generation industries all employ the use of turbomachinery. Reliability and minimizing downtime are critical in these applications. Rolling bearings are integral to the operation of pumps and compressors and must be able to withstand moderate to heavy loading and harsh operating environments. A wide variety of ball, roller, and needle bearings can be found in these machines; however, this article will focus on the most common type of bearing used, the deep groove ball bearing.
Vesconite contributes to a communication satellite launch
February 7, 2023
Vesconite Bearings, through its supply of marine rudder bearings to the MN Colibri charter vessel in June, is proud to be associated with an exciting communication satellite launch that took place in September 2022. The MN Colibri has historically transported launcher components, including communications satellites, for various heavy-lift space launch vehicles, and outfitted with the Vesconite rudder bearings allowed it to transport the Eutelsat Konnect VHTS satellite, which is regarded as an important addition to global telecommunications infrastructure.
IMPCO Machine Tools, Lansing, Mich., received orders for five microfinishing systems to be delivered to the OEM plants in Mexico and the USA. Order total is $3.5 million. Each robot-loaded system is designed to microfinish the bearing diameter to millionths of an inch (1 µm) on a family of 300 mm rotor shafts used in the drivetrain of electric vehicles.
NTN, the parent company of BCA Bearings, has announced the addition of 16 new product SKUs to the BCA aftermarket product line. BCA’s March 2022 release includes wheel hub assemblies and repair kits for a number of import and domestic applications and represents premium coverage for over 6.9 million vehicles in operation.
