I don’t know about you, but the recession of 2008-2010 sticks in my mind like a bad penny. Since that time, I am never able to simply say ...

There is often a lively debate early in a program when we are discussing the pros and cons of laser welded ring gears vs. bolted ring gears. Just 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.

I don’t recall a single bearing class where someone didn’t want to know what the largest bearing ever made was. From my stint as a bearing engineer...

For Mark Findlay of UK specialist driveline consultancy Drive System Design, reducing gear noise to suit the low noise levels in an electric vehicle cabin has meant throwing away the rule book.

A reader asks: I have heard that new axles no longer need a break-in period. True or false?

It's not a show title that rolls off the tongue, but the Industrial Automation North America and MDA NA @IMTS 2014 show nevertheless may well be one to remember.

Finding picture books for kids old enough to appreciate them can be a daunting task. There are, of course, the usual suspects--celebs, athletes, boy bands, girl bands, and so on, but not much of substance. That's where David Janosz Jr. enters the picture.

This paper summarizes the chemical, metallurgical and physical aspects of bearing steels and their effect on rolling bearing life and reliability.
