  • Confused about spindle bearings for Bridgeport...

    2014-11-12 · The 4-bearing stack might do some good if you are planning to do a whole lot of work requiring extremely high lateral spindle stiffness, but I suspect for 99.6% of all other work, it's a waste of money and bearings. Don't downgrade the bearing accuracy to ABEC 5, though, that's just asking for disappointment down the road.
