In this century’s complex, ever- changing world of manufacturing, such capabilities as hardware and software expertise, effective location and distribution, business savvy and yes, even luck, are some of the cardinal requirements for running a successful business.

Last week in our bearing shaft and housing fit discussion, we covered the IT chart — along with the shaft and housing charts — just to understand t...

Previously we discussed how to determine your cup interference fit based on thermal expectations. Then we discussed how the bearing cup contracts a...

Engineers typically learn that the bearing L10 life can be estimated using the so called “C/P method” — or the “basic rating life” of the bearing, a method rooted in the 1940s. Major developments have since led to the “modified rating life,” released in ISO 281:2007, which includes the aiso life modification factor. In this paper a succession of equations used for bearing life ratings are reviewed, and current bearing life rating practices are discussed in detail. It is shown that — despite the introduction more than 30 years ago of the adjustment factor of the basic rating life, and the standardization in 2007 of the aiso modification factor — use of these improved calculation methods are not practiced by all engineers. Indeed — many continue referring to the old model as a way of seeking compliance with existing, established practices.

The next step in our aluminum housing series is to determine where the cup interference is going. If we press a cup with 100µm interference into a ...

The interference fit that cups should have in an aluminum housing seems to be a subject that comes across my desk in regular intervals. Of course, ...

It seems preposterous in the whimsical, wireless world of today, but in 1977 cinema’s greatest visioneers came together and decided the pinnacle of robotic technology in the future would be a motorized trash can.
