Our precision spindles use ABEC-7 cylindrical roller shrink-fit to the spindle and angular contact for thrust loads. ... They also came up with a very tidy and extra-rugged purpose-built unit consisting of opposed steep angular contact bearings with very thick raceway rings, 2344(00)/SP, specifically to be used in conjunction with the above ...

Angular-contact ball bearings consist of rolling balls between concentric grooved races. This type of bearing is useful for withstanding combined loads (radial and axial). The greater the angle, the higher the load capacity of the bearing in an axial direction. Angular-contact ball bearings are one of the most common spindle bearings. Radial or ...

Used to be back then and before some bearing manufacturers made precision double row angular contact bearings that somehow where assembled preloaded and ready to install. Early Logan lathes used similar bearings along with I suspect round dials Monarch 10EE's(for the rear bearing), essentially they were specials and have not been made for ...

My only experience with swapping bearings comes from my G0704 spindle which I took from tapered roller bearings to angular contact bearings. I found that I didn't have the precision and cleanliness in my home shop to easily do the retrofit. Afterwards, I found the performance to be slightly improved but nothing to write home about.
