CNC Spindle Parts Shaft & Housing? Possibly DMG Mori Seiki ??

Not sure exactly what these are, if I get any info in the future I will update the listing.

Numbers I could find on the 2 main housing parts: Nr. 630 / 39929790 / 3362328 / 60.12 

There are no numbers on the shaft, but it does seat in the one end of the housing piece so I am guessing they go together. (see pic)

It looks like the parts are new, but there are a few scuffs scratches here and there. These were in a box lot from a local CNC auction. They were with a DMG Mori part that was still wrapped up and new. The part they were in the box with had the part numbers: 2319C0301 2R090231C 2R0902301C on the packaging (that part is being sold separate). Not sure if they all go together or not, but I listed that part as well separately.
