Baldor Motor Basics: Factors that Determine Industrial Electric Bills
A good deal of confusion exists regarding
the factors that determine an industrial
electric bill. The following information
is presented to help sort out the various items on which billing is based, and to offer suggestions on measures to help control and reduce electric utility bills.
Rolling Bearing Service Life Based on Probable Cause for Removal - A Tutorial
A bearing service life prediction methodology and tutorial indexed to eight probable causes for bearing failure and removal are presented - including fatigue. Bearing life is probabilistic and not deterministic. Bearing manufacturers' catalogue (L10) bearing life is based on rolling-element fatigue failure, at which time 90% of a population of bearings can be reasonably expected to survive, and 10% to fail by fatigue. However, approximately 95% of all bearings are removed for cause before reaching their L10 life. A bearing failure can be defined as when the bearing is no longer fit for its intended purpose. For a single bearing, you can only predict the probability of a failure occurring at a designated time - but not the actual time to failure.

Harvesting Knowledge (Publishers Page)
The season of harvest is upon us. And I don't mean crops, although here in the U.S. Midwest, there's plenty of that going on, too. No, what I mean is knowledge, because in addition to being the end of the growing season, the transition between summer and fall also marks the busiest time of year when it comes to trade shows, conferences and industry gatherings.
