Given yo...Hi CJames K, and thanks for the feedback! Given your level of understanding on the topic... we have not taken what you would consider a deep dive into shaft alignment... though we have hit on the topic in 3 or 4 lighter posts like the following one comparing dial and laser alignment (http://www.couplinganswers.com/2014/12/shaft-laser-alignment-3-benefits-over.html). Regarding testing, we actually do quite a bit of testing in our test lab to simulate all types of environments... but spider life (or any coupling life) is notoriously difficult to predict because (as I'm sure you know) so many environmental factors (which generally are not static) come into play. If you are a reliability guy... we certainly advocate laser or dial indicator alignment (http://www.couplinganswers.com/2014/10/top-reason-for-coupling-failure.html), and if you are an OEM or end user and would like further follow up with one of our application engineers, please don't hesitate to holler (http://www.lovejoy-inc.com/support/).Elliot Wilsonhttps://www.blogger.com/profile/14658081557842619631noreply@blogger.comtag:blogger.com,1999:blog-569855068731833923.post-6298980231767805482015-11-25T10:00:39.708-06:002015-11-25T10:00:39.708-06:00This site is great!

Have you ever obtained vibration data to support determining life of a spider when there is some amount of misalignment, i.e. "if vertical ips p/k is above 0.1 ips, your life is estimated at....?". Mignt not be possible but there might be enough data to try. On the flip side, you can always take more data than you have answers for! haha.

When subject to misalignment, the elastomeric flexing "spider" is designed to accommodate it (to its catalog ratings), but, in doing so, absorbs energy which is then transferred into heat. By minimizing shaft misalignment, you will minimize the amount of heat generated in the coupling... allow your system to run more efficiently... and likely get more life out of your elastomeric flexing "spider" element.
