What should be dimension of press fit on this shaft?
Our "engineer" bought a bearing and bar of precision ground rod. It
easily slipped through the bearing and since it had screws to lock it down all was find untill. Untill i read the literature that came with the bearing and it said to have a "Press Fit" if using their bearing for "heavey loads" I just guessed that the 6,000 + lbs we were going to support qualified. After doing some calculations our "engineer" said i was right. So he ordered some bar stock that has to be machined. I told him to look it up in Machinerys Handbook for the tolerance but he got it all wrong. When i tried to find it in there i found the newer additions were a little confusing. So all i want to know is if our bearing is 1.5000 what should the shaft be turned down to. The width of bearing is about two inches. Thanks Rosco |
