Schaeffler has provided tips and guidance for engineers on how to select the most appropriate rolling bearings for their application requirements. Rolling bearings are critical components in rotating machinery, production systems and vehicles. Mechanical design engineers often have to specify and select suitable rolling bearings. Even simple shaft systems subjected to radial and axial loads running at defined speeds can still place large demands on the rolling bearings. The adjacent housing, for example, influences the shaft and the design of the bearings. Other factors, such as temperature or sealing requirements, are also important. The designer therefore has to find an appropriate method of supporting the shaft by using rolling bearings in such a way that the loads involved, the speeds required, the adjacent construction and environmental conditions, are all taken into account in order to ensure a reliably functioning shaft system. In some cases, the designer may be able to use his...

Keithley Instruments will broadcast a free, web-based seminar entitled 'Tips, Tricks and Traps for On-Wafer Probing' on Thursday 28 January 2010. This one-hour seminar will demonstrate the best practices for on-wafer probing and how to identify and solve common problems. Those who attend this seminar will learn: how to cable for accurate low-current DC measurements, accurate CV measurements and ultra-fast and pulsed IV measurements; the benefits of using Keithley-supplied cables and accessories to perform DC, CV and ultra-fast and pulsed IV measurements; proper grounding and guarding techniques; selecting the proper types of interconnect cables; and how to troubleshoot interconnect problems. The event will conclude with a text-based question-and-answer session. The Tips, Tricks and Traps for On-Wafer Probing seminar is recommended for test engineers and test engineering managers with a basic understanding of wafer probing. The content is appropriate for engineers working with ...
