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.

Evaluation of an internally spring preloaded four contact ...

In a conventional spindle bearing the rotation causes a centrifugal force F c on the balls and the inner ring which results in a radial expansion of the inner ring ( Updelta x_{rad} ) and a movement of the balls. This leads to changing contact angles resulting in an axial displacement of the inner ring ( Updelta x_{ax} ).The changed contact angles cause a …
