Wind turbine gearboxes are subjected to a wide variety of operating conditions, some of which may push the bearings beyond their limits. Damage may be done to the bearings, resulting in a specific premature failure mode known as white etching cracks (WEC), sometimes called brittle, short-life, early, abnormal or white struct
Slow speed operation of fan systems within the air handling industry is generally performed due to two reasons: a coast down operation is required for hot (induced draft) fans to cool down before shutdown (often by using a turning gear), and operational efficiency improvements can be achieved during non-peak periods by slow s
Bearings used to support main spindles on machine tools must be capable of higher speed and greater rigidity. This is true in that any main spindle that turns together with a tool or work piece mounted onto it is one of the critical machine tool components that directly affects machining efficiency and accuracy of the machine
Siemens has announced the official launch and general availability of the Siemens Additive Manufacturing (AM) Network, following pilots and successful implementations with customers and partners, including Decathlon, Siemens Gas & Power, Siemens Mobility, HP and Materialise. The Siemens AM Network provides an advanced clo
AD’s president of the industrial and safety Division–U.S. Marisol Fernandez was honored with the Impact Award at the October 2019 Industrial Supply Association’s Women Industrial Supply Executives or W.I.S.E. Summit. This award honors commitment to advancing the development and influence of women in the industrial channel.
Mechanical guiding systems, such as crossedroller bearings, work well for most motion control applications; however, when precision, angular repeatability, and geometric performance (runout, straightness) are critical or where submicron bearing rumble is problematic, air bearings are recommended. An air-bearing stage is a rotary or linea
In the area of clamping and locking, Winco offers numerous toggle clamp versions for any conceivable application. To better meet specific customer needs, the toggle clamp product range now also includes a wide range of new developments and improvements as well as an expanded selection of accessories. The sta
This article takes a look at alternative-material, non-metal bearings, and it turns out the first bearings of that type - wood, in this case, were the norm - not an alternative. Bearings make the world go ’round. Much like gears, bearings are used in practically anything you can think of—from toys to tit
What is the recommended method of gripping a spinning shaft (with up to 130 hp of rotational energy) to install pre-tension thrust bearings and conventional thrust bearings (load = hundreds of pounds) when the shaft cannot have any high points because it must pass through an area of tight clearances to assemble? Will snap rings still wit
In vehicles, the transmission from the steering wheel to the wheels is often carried out by a rack and pinion drive. In standard industrial rack and pinion drives, the angle between the pinion axis and the rack is 90°. Due to installation conditions in the vehicle, however, the axis angle between pinion and rack usually has t
The Robotic Industries Association (RIA), part of the Association for Advancing Automation (A3), has announced that North American robot unit orders are up 5.2% through the third quarter, compared to 2018 results. So far this year, North American companies have ordered 23,894 robotic units, valued at $1.3 billion. &
Passenger transport today moves significantly faster than ever before, often operating on separate tracks especially designed for high-speed trains. Accordingly, high-speed rolling bearings are very important components in the bogies of trains today. Maximum train speeds currently reach 380 km/h (236 mph) in the latest high-s
American Bearing Manufacturers Association (ABMA) Standard 9 and ISO 281 give equations for calculating the basic dynamic radial load rating for ball bearings. These equations are based on a number of assumptions, many of which are not valid for thin-section bearings. (Thin-section bearings are described in ABMA standard 26.2
The ROBA-brake-checker module by Mayr Power Transmission is not only able to monitor and supply safety brakes without the use of sensors—it also supplies data, and therefore provides intelligent safety. At the SPS 2019 in Nuremberg, the company is presenting new designs of the module (Hall 4, Stand 278). This opens up new possibilities
Today’s industrial operations run on information to meet production targets, to reduce waste and energy usage, to improve processes, and more. But information is only effective if workers can readily access it and easily understand it. Modern HMI software can give workers the information they need, in the time, place and format that the
