Moore #3 spindle bearings - Practical Machinist
A vert mill spindle uses a pair of angular contact at the nose, and a single spherical bearing at the back end. The Moore design is much stiffer, allowing the use of longer bars before chatter sets in, and just better for using a single point tool, including a fly cutter.
