Backing Bearings (Z-Mill) for Highly Precise Rolled Products

Z-High mill rolls; Back-up bearings; The combination of high pressure and tension makes the mill capable of rolling material thin and flat. "Backing bearings in the middle of the roll are subject to heavier loads than those at the ends of the roll. As the middle bearings wear more than the others, they should be replaced more often."

General | Proper bearings for a mill spindle rebuild?

Angular contact bearings seem to be interesting although I suspect I might want to combine it with another bearing type to ensure it can handle all types of loads. And from what I gather, ordinary ball bearings won't support thrust loads that might arise from heavy milling although from what I can tell this is exactly what this mill already uses.

Bridgeport Mill spindle bearing replacement

I've been rebuilding my 1958 BP for a couple months now. This is a very low budget BP for use in my garage so when it came to replacing the spindle bearings I really didn't want to pay $300 for bearings on a mill that I only spent $350 for to begin with. So I found a "pair" of angular contact bearings on ebay for lowly sum of $40 shipped.
