Sam,

Where did you get that information? Timken's website and their catalogs do not list that bearing.

Danny

Thanks Sam. I'm curious too, I checked the web and couldn't find it. Maybe I didn't look hard enough??

I believe that there is a place on our website to get bearing calculations. If not I can get most of them for you if you have a need. Just send me an email and I will find them and send them back to you via email.

Here is the link for the bearing frequency calculator on the Timken Site.

Thanks Don. I did manage to find that calculator. The problem was that the part number "15716" is not recognized and a search on the site didn't come up with anything either. Can parameters such as "*" or "/" be used for searching there?
