There's not that many cup and cone size combos really. If you have the cup outside dia. and the cone inner dia where it goes on the spindle, a common bearing set can likely be matched up. If you have a seal and bearing place to go to, the catalog or computor should have the sizes. The bearings come in sets, A set, B set, and so on. I just don't have the measured sizes for you, sorry. An older parts guy quite often can rhyme this stuff off from memory. Not sure what a guy could find on the internet, on the subject. With a little searching, you might be able to save yourself a few bucks. Sniper
