I am wanting to build a "small" cnc chucker lathe from the ground up.
I have the spindle out of one of the 5C indexers, with a 45mm OD. I just got in some pillow block bearings (http://www.vxb.com/Merchant2/merchan...ategory_Code=), and they look like they might work with some preloading, but I have no data on the precision of the bearings. For that price, I am only expecting the lowest grade. :-/
Questions:
1) Anyone familiar with these 45mm pillow block bearings? They are simple deep groove type. Any preload/RPM suggestions? I would like to see around 3000rpm.
2) Are there taper roller bearings available anywhere with a 45mm ID? From what I understand these would be optimal, but I cannot find any anywhere!!
Thanks-
Colin
